PHP Intl Class Peer to Peer Serverside Tutorial

PHP Intl Class Peer to Peer Serverside Tutorial

Sometimes, in programming …

• you’re stringent … especially regarding security matters, but most of the time, when we organize the programming rules, so to speak, we prefer it when …
• you’re flexible

… and so, back with GraphViz via PHP on AlmaLinux Require Once Tutorial when we used a …

• require_once … PHP calling paradigm (we’re not going to change it, because it is still fine) … we’re wondering now, why we didn’t use an …
• include … paradigm, because the arrangement was optional

… as per …

The include (or require) statement takes all the text/code/markup that exists in the specified file and copies it into the file that uses the include statement.

Including files is very useful when you want to include the same PHP, HTML, or text on multiple pages of a website.

… as with the optional nature of today’s PHP include paradigm call of a new i_eg_js.php piece of PHP we’ve decided should …

• not only “back up” yesterday’s clientside i_eg.js (tweaked today to fix possible caching issues) external Javascript (introduced in yesterday’s PHP Intl Class Peer to Peer Tutorial) … but quite literally …
• rewrite that clientside i_eg.js external Javascript … “when the need arises”

Can’t “when the need arises” be contentious?

… we hear you ask. Good question! We could jump the gun, before code is properly ready using PHP glob to look for files existant under the ./i_*eg.php file specification, and match them to what we have in the i_eg.js external Javascript, adding new entries when a mismatch is found. But that is where “local knowledge” can come into play (and the other aspect to “local knowledge” here is that the suite of PHP intl class using web applications all have a file specification suiting /i_*eg.php here). Genericity has it’s limits sometimes, in other words. Take a look at what we do to time this PHP rewrites external Javascript serverside intervention safely …

<?php

<?php
// i_eg_js.php

$iscand=false;

$bitsphpa=explode(' candidates="', $jscont);
$bitsdesca=explode(' candidatesdesc="', $jscont);
if (sizeof($bitsphpa) > 1 && sizeof($bitsdesca) > 1) {
foreach (glob('./i_*eg.php') as $pfile) {
$iscand=false;
$pcont='';
if (strpos(' ' . explode('"', $bitsphpa[1])[0] . ' ', ' ' . basename($pfile) . ' ') === false) {
foreach (glob('./' . basename($pfile) . '*GETME') as $ppfile) {
$iscand=true;
}
}
if ($iscand) {
$pcont=file_get_contents('./' . basename($pfile));
if (strpos($pcont, '>Show ') === false) { $iscand=false; }
}
if ($iscand) {
$jscont=str_replace(' candidates="' . explode('"', $bitsphpa[1])[0] . '"', ' candidates="' . explode('"', $bitsphpa[1])[0] . ' ' . basename($pfile) . '"', $jscont);
$jscont=str_replace(' candidatesdesc="' . explode('"', $bitsdesca[1])[0] . '"', ' candidatesdesc="' . explode('"', $bitsdesca[1])[0] . ' ' . str_replace(' ','_',explode('"',explode('<', explode('>Show ', $pcont)[1])[0])[0]) . '"', $jscont);
file_put_contents('./i_eg.js', $jscont);
$bitsphpa=explode(' candidates="', $jscont);
$bitsdesca=explode(' candidatesdesc="', $jscont);
}
}
}
}

?>


Yes, we share via a GETME filename suffixing set of rules here at RJM Programming, and we only do that, and upload codefiles and GETME files to the RJM Programming web server via sftp means, when we’ve tested the code.

How is this new include paradigm PHP called in each PHP web application of …

1. Sorting Words PHP code changed today this way and changed this way yesterday
2. Language Name PHP code changed today this way and changed this way yesterday
3. Region Name PHP code changed today this way and changed this way yesterday
4. Currency PHP code changed today this way and changed this way yesterday
5. Current Datetime PHP code changed today this way and changed this way yesterday

? As simple as now having …

<?php

include "i_eg_js.php";

?>

… up near the top of the PHP code and, unlike require_once these PHP suite web applications will not fall over should they not find i_eg_js.php in their same web server folder, and meaning the use of any of “the peerage” can look for new members without constantly having to update that external Javascript list, it flowing through to that dropdown, created via that external Javascript, updated, as required, by this new PHP include paradigm intervention.

Did you know?

If we’re not introducing any new PHP members of “the peerage” today, how did we test this thinking above, to our satisfaction? Simulating the scenario on our test Apache/PHP/MySql MAMP web server is how we tested it. We went, at the local macOS command line …


cp i_eg.php i_new_eg.php


… and tested, to be satisfied that the external Javascript remained unchanged, and then went …


cp i_eg.php i_new_eg.php_GETME


… to see that the external Javascript was appropriately changed, as you can see occurring in today’s tutorial picture. When happy, we undid all these changes, ready for when a new member of “the peerage” is really added, and then we’ll test further.

• a clientside (external Javascript called by the PHP) approach to gathering this PHP intl “Internationalization” class work into a suite of peer to peer web applications so that they can easily access each other rather than worrying about any web browser address bar (or bookmark) recalling of URLs in that group (once you get one under your belt, that is) … as maybe, another day, we’ll develop …

PHP Intl Class Word Sorting Primer Tutorial

The PHP intl “Internationalization” class can help with an issue that has haunted me for many years. When you sort words in my English biased way, will they be sorted the same way in other languages, given alphabets and diacritics (with thanks to this excellent link regarding an example we’re defaulting to in the web application) and emojis and non-ascii characters, in various keyboard configurations, which might happen with words expressing the human condition? Luckily, the PHP intl class has …

<?php

function sortit($arr, $thisloc) {
global $dias, $dia, $tabis;
$coll = collator_create( $thisloc );
//$arr = array( 'at', 'às', 'as' );
//var_export( $arr );
if (!isset($_GET['sorttype']) && !isset($_POST['sorttype'])) {
collator_sort( $coll, $arr );
} else if (isset($_GET['sorttype'])) {
if (strpos($_GET['sorttype'], 'REGULAR') !== false) {
collator_sort( $coll, $arr, Collator::SORT_REGULAR );
} else if (strpos($_GET['sorttype'], 'NUMERIC') !== false) {
collator_sort( $coll, $arr, Collator::SORT_NUMERIC );
} else if (strpos($_GET['sorttype'], 'STRING') !== false) {
collator_sort( $coll, $arr, Collator::SORT_STRING );
} else {
collator_sort( $coll, $arr );
}
} else if (isset($_POST['sorttype'])) {
if (strpos($_POST['sorttype'], 'REGULAR') !== false) {
collator_sort( $coll, $arr, Collator::SORT_REGULAR );
} else if (strpos($_POST['sorttype'], 'NUMERIC') !== false) {
collator_sort( $coll, $arr, Collator::SORT_NUMERIC );
} else if (strpos($_POST['sorttype'], 'STRING') !== false) {
collator_sort( $coll, $arr, Collator::SORT_STRING );
} else {
collator_sort( $coll, $arr );
}
}
//var_export( $arr );
for ($ij=(-1 + sizeof($arr)); $ij>=0; $ij--) {
$tabis=str_replace('<td id="sorttd">', '<td id="sorttd">' . $arr[$ij] . '<br>', $tabis);
}
echo $tabis;
}

… to verify, one way or the other, and thanks to a heads up from this useful link here, further to yesterday’s PHP Intl Class Language Names Primer Tutorial.

PHP Intl Class Language Names Primer Tutorial

You might have noticed over the last week (further to yesterday’s PHP Intl Class Region Names Primer Tutorial) or so, how useful …

Locales

… are as a data item involved with PHP intl “Internationalization” class programming work.

As an example Locale …


pt_BR


… we’ve been making quite a lot out of the “BR” ISO-3166 2 letter Country Code as the suffix of such a Locale. But what about the prefix of Locales? That prefix maps to an ISO-639 Language Code, meaning any derivable (ie. via our keyboard onkeydown and oninput logics) set of Locales could tell us (at the very least) two types of information, exemplifying the case above …

All “code talk” above, but what about some Language Names, because you are not likely to ask down at Copacabana Beach …

Ei, cara! Você falar es?

That’s where we thank https://www.php.net/manual/en/locale.getprimarylanguage.php for the “heads up” to use code as per the followup to $lochelper and $lochelpertwo data flows to help with these Language Name determinations …

PHP Intl Class Region Names Primer Tutorial

Apart from Ghostbusters who do you turn to when you want to know what a resident of a region calls their region?

Still, Ghostbusters, you must be pulling my leg?!

Anyway, further to yesterday’s PHP Intl Class Currency Primer Tutorial, we’ve turned to good ol’ PHP.net, as usual (when it comes to many matters PHP).

In amongst all the ISO code usage we seek when interfacing to the PHP intl “Internationalization” class, because they are definitive, even so, we feel we need to allow users to enter Country Names, as one concept, especially as Country Names have been there before any ISO codes even started. The trouble with Country Names is twofold …

• it is not a reliable index_er, if you get my drift, because there are lots of forms, in any language you pick, for what a Country Name is
• at least for an English representation of a Country Name we’d like consistency, and, happily, the PHP intl “Internationalization” class can provide it

… via PHP code of the ilk …

<?php

echo "<p id=pdfmt>" . locale_get_display_region(urldecode($_GET['locale']), urldecode($_GET['displaylocale'])) . "</p><br>";

?>

As you might imagine, this discovery can have mildly wide ranging implications … well, you had to be there … on …

• a new “proof of concept” i_region_eg.php Region Names Internationalization web application … the crux of which filtering through to …
• a tweaked i_cur_eg.php Currency and Numbers Internationalization web application … and …
• a tweaked i_eg.php Datetime Internationalization web application

…PHP intl class suite of web applications we’re not letting Ghostbusters anywhere near!

PHP Intl Class Currency Primer Tutorial

We’re back with the PHP intl “Internationalization” class, today, last talked about with the recent PHP Intl Class Datetime Keyboard Events Tutorial, this time discussing …

Currency Internationalization

… topics. Again, we found the Locale data item, as with Datetimes, the main data item of interest. But, any one Country can use more than one Currency (defined by an ISO-4217 3 letter Currency Code) in this new PHP Intl using Currency web application we’ve started developing today, and on a Locale selection we choose the first such one, and leave it open to the user to be able to type in their own ISO-4217 three letter Currency Code, as required.

We got great help from https://stackoverflow.com/questions/76825595/php-format-currency-issue with codeline ideas, such as …

<?php

$formatter = new NumberFormatter(urldecode($_GET['locale']), NumberFormatter::CURRENCY);
if (isset($_GET['amount'])) {
echo "<p id=pdfmt>" . $formatter->formatCurrency(urldecode($_GET['amount']), urldecode($_GET['currency'])) . "</p><br>";
} else {
echo "<p id=pdfmt>" . $formatter->formatCurrency(76543.210, urldecode($_GET['currency'])) . "</p><br>";
}

?>

The work of Datetimes, ahead of all this, has meant it is easier to get “further down the track” for today’s “proof of concept” i_cur_eg.php PHP code start, that has keyboard event and dropdown logics all in there, and which you can try below …

As far as “user interaction” goes with our Current Datetime PHP web application of PHP Intl Class Datetime Google Translate Tutorial we’ve been thinking …

• the user would be more likely to use the dropdown element selection methods … but supposing …
• the user uses the keyboard to enter Locale and/or Timezone

… and, as of yesterday’s logic, that would have been quite unwieldy, especially regarding timezone entries.

And so, today, we’ve added keyboard onkeydown and oninput event logics to cater for several scenarios we can “shortcut” those user requirements, often down to the entry of a couple or a few characters, and from there click appropriate created links in …

PHP Mbstring Multibyte String Primer Tutorial

Our (Mac OS X laptop) local MAMP web server is an Apache/PHP/MySql web server. In this environment you can find out a lot with some PHP code as per …

<?php phpinfo(); ?>

… and if, in doing this, you find a reference to the “mbstring” Multibyte String Information functionality existing, you are a lucky candidate to introduce some internationalization code into your PHP code, for those occasions where the destination language uses a UTF-8 character set where individual characters can not be described by the ascii character set from decimal 0 to decimal 255. In other words, it takes more than one byte to describe each character of the language. There are many languages like this, a few being the Chinese languages, Japanese and Korean.

We followed a lot of the advice of the very useful link (thanks) to create some PHP called …

• mbstring_test.php

… where we show what we always suspected but were too shy to ask, and didn’t flesh it out before … doh! … you can’t split a Chinese phrase’s characters into their individual characters and expect those characters individually translated bring you back to the sense of the Chinese phrase to start with.

So we take the Chinese phrase 火车票 (which translates into English as “Train tickets” … and we thank Google Translate for help with all this) and use PHP mbstring’s mb_str_split to properly split the Chinese into its constituent multibyte (UTF-8) characters (and along the way, show that PHP str_split messes up this same task, as you’d probably guess would happen), and then translate all these into English using Google Translate, as an intellectual exercise.

If this exercise makes you …

• a) fall on the floor laughing
• b) hit a gong with a huge hammer
• c) cook up some deep fried dumplings
• d) put the left chopstick in the right ear and the right chopstick in the left ear (please ask for adult supervision) … translation: do not do this
• e) while reading you sweep the cat under the rug (no animals were harmed in the making of this blog posting)

… then we’re here to tell you that you need to take a Bex and have a lie down.

We are just showing in PHP that if the mbstring functionality is available to you, that the mbstring library of functionality can help with some Internationalization issues you may be grappling with and that this PHP code you could try via this live run link.
