PHP Mail via Exim Better Return Deployment Tutorial

Yesterday’s PHP Mail via Exim Better Return Primer Tutorial set up a …

  • framework part of an overall solution to a way to nuance PHP mail‘s return value, in an Exim Mail Server environment … and today …
  • we present a “use of” this framework for a “total solution” for a particular application need

Too boring for you?! But you see …

  • any non-synchronous scenario is bound to involve a “somewhat messy” arrangement … and …
  • the framework is solid and can remain, and the “use of” is fairly easily mimicked for another application usage … and …
  • parts of the “use of” to an “always used” by us tool web application which sends inline HTML emails (and so, effectively becomes merged into the “framework” of the solution) lessens the impact of the “somewhat messy” description above

To summarize, at least for us, we see this as a useful step forward, and besides that, we want to put this down in words.

Okay, to that last point above, we have the now changed emailhtml.php we use most often, in combination with Ajax and FormData to send out inline HTML (form) emails via our Exim Mail Server via PHP mail function. It changed in a function …

<?php

$isinline=false;
if (isset($_GET['inline']) || isset($_POST['inline'])) { $isinline=true; }

function zmail($zris, $zxsis, $ztis, $zhis) {
global $subjarr, $fflist, $ffname, $localdt, $fromer, $isinline;
// file_put_contents("091.091","");
if (strpos($zxsis, "[") === false && strpos($zxsis, "<") === false && $zxsis != "") {
$zxsis.=" at [date] for [files]";
// file_put_contents("092.092",$zxsis);
analtoken($zxsis, "");
}
// file_put_contents("093.093",$fflist);
subjtokenization($fflist, "files");
subjtokenization($ffname, "name");
// file_put_contents("094.094",$subjarr[0]);
if ($ffname == "") { $zhis=str_replace("<files>", $fflist, str_replace("[files]", $fflist, $zhis)); }
$zhis=str_replace("<files>", $fflist, str_replace("[files]", $fflist, str_replace("<name>", $ffname, str_replace("[name]", $ffname, $zhis))));
// file_put_contents("095.095",$xsis);
//$xretmd="";
//$xxretmd="";

if ($isinline && (isset($_GET['waitforreturn']) || isset($_POST['waitforreturn']))) { // relies on crontab scheduling of snapshotexim.ksh
$refd='' . date("Y-m-d H:i:s");
$cursecs=explode(':', $refd)[2];
$curtens=substr($cursecs,0,1);
$subsecs=substr($cursecs,1,1);
if ($cursecs > 56) {
sleep((61 - $cursecs));
$refd='' . date("Y-m-d H:i:s");
$cursecs=explode(':', $refd)[2];
$curtens=substr($cursecs,0,1);

$cursecs=explode(':', $refd)[2];
$curtens=substr($cursecs,0,1);
$subsecs=substr($cursecs,1,1);
}
if ($curtens < 5) {
$refd=substr($refd, 0, 17) . '[' . $curtens . (1 + $curtens) . ']';
}
if (file_exists($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.php")) {
unlink($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.php");
}

} else {
file_put_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.txt", '' . $_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . ' "' . substr($refd, 0, 18) . '"');
exec('chmod 666 ' . $_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.txt");
}
}

$outretm=mail($zris, subjtokenization($zxsis,"subject"), $ztis, $zhis);


if ($isinline && (isset($_GET['waitforreturn']) || isset($_POST['waitforreturn']))) { // relies on crontab scheduling of snapshotexim.ksh
$maxwait=91;
$curwait=0;
while ($curwait < $maxwait && !file_exists($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.php")) {
sleep(1);
$curwait++;
}
$reth="";
if (file_exists($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.php")) {
$reth=file_get_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "snapshotexim.php");
if (strpos($reth, "no immediate delivery:") !== false) {
echo "<html><body><p>no immediate delivery</p></body></html>";
exit;
} else {
echo "<html><body><p>delivered from exim</p></body></html>";
exit;
}
} else {
echo "<html><body><p>not sure if exim delivered</p></body></html>";
exit;
}
}


return $outretm;
}

?>

… telling us the caller of this Exim emailing PHP tool needs to define a new argument called waitforreturn and the usual argument called inline for this solution to kick in. With our recent Sudoku game (that we last talked about with PHP/HTML/Javascript Sudoku Game Inline HTML Email Tutorial) we started to make that happen …

… meaning a button prompt window answer of Robert:RMetcalfe15@gmail.com (for example) in the second chance inline HTML email collaboration and sharing logic for index.php PHP Sudoku game will try to email an inline HTML email to the recipient via PHP mail through RJM Programming’s Exim mail server and will wait around to examine the relevant snippet of the /var/log/exim_mainlog log file to determine whether it should offer an “a” link “mailto” alternative approach because the logs show “no immediate delivery” in that relevant snippet of logging, while that Robert:RMetcalfe15@gmail.com was selected by the user to not offer this alternative with our Sudoku game.

PHP Mail via Exim Better Return Primer Tutorial

We are exploring a way to improve on the PHP mail return value telling you nothing about whether the email gets off to the intended recipient. One step, here at RJM Programming, is to verify if the email has immediately been sent off according to our Exim mail server logs.

We are turning to a crontab operated (ie. scheduled) call to a new …

… to, in our MAMP local Apache web server wooooorrrrrlllllddd would work with either …


echo '/Applications/MAMP/htdocs/ "2022-12-20 11:4[01]"' > snapshotexim.txt
ksh ./snapshotexim.ksh # may populate /Applications/MAMP/htdocs/snapshotexim.php

… or …


echo '' > snapshotexim.txt
ksh ./snapshotexim.ksh /Applications/MAMP/htdocs/ "2022-12-20 11:4[01]" # may populate /Applications/MAMP/htdocs/snapshotexim.php

… methodologies to place a relevant “slice” (dated 2022-12-20 11:40 or 2022-12-20 11:41) of the Exim mail server log into a file in our Apache web server’s Document Root called snapshotexim.php for ongoing local work to follow.

We prefer the first way because our future PHP interfacing can better write out “the intelligence” into snapshotexim.txt itself.

Up with crontab, in a Korn Shell procedure that runs every minute, we place (code like) …


if [ -f "$HOME/snapshotexim.txt" ]; then
if [ -f "/etc/init.d/snapshotexim.ksh" ]; then
ksh /etc/init.d/snapshotexim.ksh
fi
fi

… ready for our journey of discovery to continue!

Did you know?

If you are thinking of implementing a solution of this ilk, within the next phase of the procedures we’ll tackle into the future, you will need a PHP reader of snapshotexim.php above, via file_get_contents or HTML and Javascript and Ajax reader such as eximsnapshot.php as some sort of starting point.
