PHP passthru Document Title Primer Tutorial
We are a bit in awe of the PHP “passthru” function (again, “you had to be there”) as that direct conduit to output from an underlying operating system command. We’ve been in such awe, we have only ever dared use it on its own on a PHP codeline. But yesterday’s Xcode Command Line Project GUI Executable Tutorial got us wondering if we could tweak improvements, so that we can improve on …
- a “passthru” inspired webpage content just containing that underlying operating system command content … but which misses out on defining a webpage “document.title” which is shown (usefully in a web browser tabbing situation) on that webpage’s web browser tab of use … but what if we can have …

? Happily, yet it being a tad awkward and kludgy, it’s possible, and we wrote a PHP “proof of concept” passthru_test
php‘s web application with a defined document.title (versus web application without a defined document.title) source …
<?php
// passthru_test.php

if (isset($_GET['justpassthru'])) {
passthru('echo "PHP passthru content with no HTML embellishment"');
} else {
echo "<html><head><title>PHP passthru content has HTML document.title embellishment</title></head><body><pre>" . passthru('echo "PHP passthru content has HTML document.title embellishment"') . "</pre></body></html>";
}
exit;
?>
… can have us improving yesterday’s PHP code find_executable_and_go.php web application‘s mildlychanged find_executable_and_gophp which we, yet again, want you to download to (the Document Root of) a macOS MAMP local Apache/PHP/MySql web server environment, “Intranet style”.
