AlmaLinux TimeZone Places Associative Array Tutorial
Have you been waiting for more “heads up” regarding issues we’ll have moving from a PHP (of a version starting with a 5) to a PHP (of a version starting with an 8)? Join the crowd?! But so far, it hasn’t been that bad. That is, until we started into looking at the PHP TimeZone functionalities. Going back to a previous time of referencing this, at the recent Google Charts Geo Chart Region Picker Conditional Positioning Tutorial, associative array based codelines like …
<?php
$ourtz=new DateTimeZone($zzbit);
$ourtzgl=$ourtz->getLocation();
$versus=str_replace('"' . '' . '"];', '"' . $zzbit . '","' . '' . '"];', $versus);
$yourgl=explode(',',('' . implode(',',$ourtzgl)));
//$versus=str_replace('"' . ' ' . '"];', '"' . $ourtzgl[latitude] . '","' . ' ' . '"];', $versus);
//$versus=str_replace('"' . ' ' . '"];', '"' . $ourtzgl[longitude] . '","' . ' ' . '"];', $versus);
$versus=str_replace('"' . ' ' . '"];', '"' . $yourgl[1] . '","' . ' ' . '"];', $versus);
$versus=str_replace('"' . ' ' . '"];', '"' . $yourgl[2] . '","' . ' ' . '"];', $versus);
?>
… worked and meant codelines avoiding associative array logic, in favour of numerically indexed array thinking, like above (thanks to implode) were not needed then, on CentOS, but are needed now, in a redesign, on AlmaLinux, in the changed TimeZone Places (the old way) (and TimeZone Places (the new way)) tz_places.php PHP code.

Google Charts Geo Chart Region Picker Conditional Positioning Tutorial
Because of the work at Curl HTTP Request Methods Tool Tutorial we can now …
- conditionally (depending on the existence of the Google Charts Image Charts API) …
- determine the positioning of Region Picker functionality elements
… further to yesterday’s Google Charts Geo Chart Region Picker Alignment Tutorial.
We start with non-mobile improving the positioning for the “letter breadcrumbs” and “middle dropdown” elements …
var imagechartthere=true;
function checkimagechart(iois) {
var eaconto = (iois.contentWindow || iois.contentDocument);
if (eaconto != null) {
if (eaconto.document) { eaconto = eaconto.document; }
if (eaconto.body.innerHTML.replace('Not Found','Error 404').replace(/^\<br\>\<\/p\>/g, 'Error 404').indexOf('Error 404') != -1) {
imagechartthere=false;
document.getElementById('myh3').style.left='' + eval(eval('' + screen.width) * 7 / 10) + 'px';
document.getElementById('myh3').style.top='' + eval('' + document.getElementById('myh3').getBoundingClientRect().bottom) + 'px';
setTimeout(function(){
document.getElementById('tdleft').style.backgroundPosition="right center";
}, 60000);
}
}
}
//
// and then later ...
//
setTimeout(function(){
if (!imagechartthere && document.getElementById('myh3')) {
document.getElementById('more').style.left='' + eval(-170 + eval(('' + document.getElementById('myh3').style.left).replace('px',''))) + 'px';
} else {
document.getElementById('more').style.left='' + eval(eval(360 * lastiizoom / 2) + eval('' + document.getElementById('more').style.left.replace('px',''))) + 'px';
}
}, 3000);
… working via the “client pre-emptive iframe” feeling …
<iframe style="display:none;" src="/PHP/http_methods.php?url=https%3A%2F%2Fchart.googleapis.com%2Fchart" onload="checkimagechart(this);"></iframe>
… along with making the opacity toggling of the country background SVG slightly more pronounced in the changed regions_via_countries.html Region Picker.
Did you know?
Ignoring the kludginess of codelines …
ipbit=ipbit.trim();
setTimeout(function(){ ipbit=ipbit.trim(); }, 5000);
… how do you think we arrived at the need to write the second line of code for our Region Picker? Goo … anyone, anyone? … guffaw
Sir, could you repeat the question?

… positioning, useful within the realms of what is going on on the right hand side.
But now we’re wanting some horizontal integration, linking commonalities of left and right regarding the country of interest, as a user’s eyes scan across the webpage, at pivotal times.

… all feature the great [element].scrollIntoView() way to programmatically scroll, rather than use (the sometimes ignored) window.scrollTo([left],[top]); or location.href=’#[elementID]’; approaches. It has the advantage of not altering location.hash (if you see that as a plus). We’d rather not add complexity, so, yes, we prefer the [aCountryElement].scrollIntoView(); call approach, at those pivotal times. This accounts for the left hand side of the webpage agreeing to the right hand side’s vertical scroll position. But what about the other way around? There, we started applying a CSS padding-top property to relevant right hand side elements (via DOM [element].style.paddingTop=[pixelsToExtendDown]px;), at pivotal points in the programming flow.
And on double clicking a right hand side button to start creating those background Geo Chart SVG based “images” we turn on a progress cursor, at least for non-mobile platforms, because the user needs patience here, in the changed regions_via_countries.html Region Picker.

GeoJson World Countries Drag and Drop Makeover Nuance Tutorial
Nuance alert! We’re not sure if you noticed, but if you tried out the Drag and Drop functionality in the World Countries web application of yesterday’s GeoJson World Countries Drag and Drop Makeover Tutorial you may have noticed …
- for a country with lots of TimeZone places, like Brazil, you could get a decent Google Chart Geo Chart map up … but if you were to click the “Map?” link down the bottom of that iframe …
- it would fail to show a Google Chart Map Chart for that country’s TimeZone places
This fix, believe it or not, is interesting, perhaps only in an “internal use only” sense, we grant you. But our solution got us delving even more into hashtagging data, so that the solution we came up with was a hybrid whereby …
- stayed with PHP $_GET[] (ie. address bar ? and & argumented) data (versus using PHP $_POST[] methodologies) … but …
- where it came to the &data=[most of the data] part, other than its first character, we hashtagged the rest
… so that the logic flows as per usual, but we intervene at places and flesh it out via location.hash (client side only) means. We won’t bore you too much with all the places of intervention except the receiving map.php’s “easiest to get” intervention …

At first …
- we wanted the first popup window content be aligned to the top and left … and then …
- we thought it would be good to also, in “Drag and Drop land”, relevant countries nearby to the user’s drop point TimeZone Places be showing below that (and it panned out the best way to show this, for us, was via an iframe pointing at another incarnation of the tz_places.php webpage, because it could have GET arguments iso, iso2, iso3 etcetera to point at ISO 2 letter country codes, which we made more readily available (via a new data-cc global data attribute applied to the select option subelements presented) for the changed external Javascript countries.js we decided should get into the mix via a new Javascript function …

GeoJson World Coastlines Drag and Drop Tutorial
The primary aim of today’s work, onto yesterday’s GeoJson World Drag and Drop on iPad Tutorial iPad integration is to …
- add similar drag and drop logic into our World Coastlines GeoJson web application … and along the way, also for the World Countries web application …
- hold off involving the (pretty kludgy looking) vertical scrollbar of our drag and drop pin’s underlying HTML iframe …
<iframe scrolling=no frameborder=0 name=iftr id=iftr style=display:none; srcdoc="<body style=background-color:transparent;><p id=mg title='Wikipedia country page below via drag and drop to world map' draggable='true'>📍</p><br><br><div id=myh1></div><script type='text/javascript' src='./countries.js?rand=321156747657' defer></script></body>" data-src=></iframe>
… until the first drag operation starting, calls on …
parent.document.getElementById('iftr').scrolling='yes';
… proving a Javascript DOM control of the “scrolling” attribute works (as we weren’t sure, having never done this before)
It’s worth beavering away at a guinea pig web application until (just about complete) satisfaction (for now) before having a parallel set of code changes happening simultaneously, we’ve always found.
So, what happened in “external Javascript land”? No need for a “regions.js” here, as parent.document.URL can be scrutinised in that “external Javascript land” to discover which web application is the parent, and act accordingly. So changed were our changed external Javascript countries.js in …

- our GeoJson World Countries web application Drag and Drop logic worked on an iPhone … but …
- our GeoJson World Countries web application Drag and Drop logic did not work on an iPad
They’re both iOS! And usually the smaller iPhone has the problem and the larger iPad is okay when there is an odd scenario happening. So, what gives? Well, the odd thing is, it was just rearrangements of code and iframe srcdoc usage …
<iframe frameborder=0 name=iftr id=iftr style=display:none; srcdoc="<body style=background-color:transparent;><p id=mg title='Wikipedia country page below via drag and drop to world map' draggable='true'>📍</p><br><br><div id=myh1></div><script type='text/javascript' src='./countries.js?rand=321156747657' defer></script></body>" data-src=></iframe>
… that ended up helping us fix the issues. Figure this, on iPad our emoji pin could not be made visible down the bottom left of iPad screen but could be made to work in the title elements section?! Of course, we might have been having a bad day, but in our defence, even debugging in Safari via …
- iPad Safari web browser invocation …
- Apple white lead from iPad to MacBook Air …

We often turn to what we like to call …
- “long hover” (ie. on non-mobile, wait for a long while after the onmouseover event initiation to see whether the user is still hovering) … and today, a bit like that, is the new, for us …
- “long drag” (the user waits a long time between the drag initialization and the drop event)
… and because we found “dawdling” on a drag and drop fairly unnatural, we think this “long drag” idea “has legs”, in that it works well as a deliberate act made by a user, knowing at the end they benefit from their actions. For us, with our GeoJSON Map web application, yesterday, with GeoJson World Drag and Drop Pin Tutorial, the drag and drop led to …
- Wikipedia country information webpage … and today, we allow a “long drag” get you to …
- Google Maps drop position information webpage … if the “long drag” is for 10 or more seconds …

GeoJson World Coastline Function Noun Naming Tutorial
We’re working on an extension to yesterday’s GeoJson World Coastline Rivers Quiz Tutorial‘s Rivers Quiz functionality within our GeoJson World Coastlines web application, and have …
- settled on an approach … but …
- not yet finished on deployment issues
… but it is this approach we wanted to talk about today.
Our approach borrows from Object Oriented Programming (OOP) the idea that …
- just as with OOP thinking class names are like nouns and the methods within that class are like verbs … we, with our approach …
- help readability of our non-OOP functional code by including those nouns and verbs, as well as ideas like use of plurals to indicate array involvement, with our Javascript function naming
… we can best illustrate to you via showing you new functions and variables and modified code to show you this approach in code …

… function) would suffice, or if we would end up using …
- Ajax call
… to access this data, and were a bit surprised the former method was all fine. Of course there are snazzy inbuilt Javascript hierarchical calls you can make to process the data, but we find, with GeoJSON data, in the client realm (where we’re keen to stay with today’s work (though PHP serverside can, of course, be purloined to do all this work, should you have that available)), of Javascript, we just need very basic string functions …
- split (versus PHP explode)
- index (versus PHP strpos)
- substring (versus PHP substr)
- replace (versus PHP str_replace)
- push (versus PHP array_push)

There are a few interesting aspects to today’s extension of functionality onto yesterday’s GeoJson World Countries Plotted Airports Tutorial‘s GeoJson World Countries web application …
- where to modularise … we think “data collection” commonality is a good reason, and so we make these changes to intair.php
- making an (“animated emoji”) button dual purpose on top of originally being a single purpose button …
<sub title='Show Nearby Airports' onclick='doair=how(true,this); twothousand*=2; this.title=this.title.substring(0,4) + String.fromCharCode(105) + String.fromCharCode(110) + String.fromCharCode(103) + this.title.replace(this.title.split(String.fromCharCode(32))[0] + String.fromCharCode(32), String.fromCharCode(32));' data-type=9992 style=cursor:pointer; id=portsub>✈</sub>
… working with the intairsuffix global variable that could add a new GET argument where both the “port” label in &port=[value] and that [value] can affect behaviour from the intair.php PHP helper tool above …
var intairsuffix='', zhra=null, zhrb=null, kklat=0, kklong=0, doair=false, vsll=[-999.0], answered=true;
function how(atr, isub) {

Onto yesterday’s GeoJson World Countries TimeZone Times Tutorial GeoJson World Countries web application’s capabilities we want to add zooming, that doesn’t rely on web browser functionality (which continues to work).

Some readers might be aware of our “theory regarding adverbs” and “web applications” on the net …
- the most catered for adverb relates to the “where of life” … and the second banana is …
- the “when of life”
… and, further to yesterday’s GeoJson World Countries SVG Overlay Safari Error Tutorial‘s emphasis on the “where of life”, today we add in a bit of the “when of life”, something right down the line of the remit of TimeZone talents.
Seriously though, a lot of us dream of the rest of the world on a world map, and wonder what time it is in other parts of the world. Phone call to relatives? A reminder SMS call? Email a game collaboration? It could all be part of life’s rich tapestry!

What deducible data item needs to be determined for these Geo Charts to work?

Which leaves us with why any of this helps functionality within our changed countries.php web application you can also try below?
- Geo Chart can zoom into a country view …
- Geo Chart can involve emoji (🏠 &127968;) or image (SVG) circle based symbology for the “User Clicked Place” and nearby TimeZone places respectively …
- all these symbols can be clicked to open popup windows containing TimeZone Place Wikipedia webpages of relevance …
- an emoji national flag (eg. Zambia “ZA” could be used to derive 🇿🇦 🇿🇦 flag emoji) derived from those ISO-2 character codes can supplement the GeoJson (more ISO-3 character based) names presented in the underlying data, in the Geo Chart title …
- contextualizing the accompanying Map Chart … and …
- vice versa regarding hovering over symbology (which works on Map Chart, but not Geo Chart) …
- within the Map Chart iframe a “Geo” link can glean a “zoomed out” world Geo Chart view of your TimeZone places

Know your GeoJson! Yes, pretty obviously, any two GeoJson datasets might display the same in that “map plotting” sense, but one might have different and/or more “intelligence” than the other. Often, an XML has more “intelligence” than equivalent HTML (barring the use of global data attributes, that is), as today’s Corollacorollary.
And so, moving on from yesterday’s GeoJson World Coastline TimeZone Tutorial, today, we present a new GeoJson admin 0 countries we download, and upload as “countries.geojson” data set, again via the excellent HTTP://geojson.xyz/ repository, thanks.
From it, we do get a different JSON additional “intelligence” …
