Stands for: PHP: Hypertext Preprocessor (DKF: but originally allegedly stood for Personal Home Page.)
PHP is a scripting language mainly designed for web development, where it is quite popular--arguably the single most widely-used server-side language.
This [L1 ] is PHP's home page.
For Tcl's answer to PHP, see Rivet.
Or try THP for a webserver neutral way to embed Tcl code.
In the last few years, "PHP [has become] Handy off the Web, Too", although this article [L2 ] doesn't recommend it for those who already know Tcl and similar languages.
In a remarkable newsgroup posting [L3 ], Derk Gwen provides a recipe for the C implementation required to link in a Tcl library so PHP source can also interpret Tcl.
See a Tk binding for PHP at [L4 ]
Incidentally, our own SS maintains an attractive "web-based interactive shell for PHP" he and his collaborator call "PHP Interactive" [L5 ].

The following might be an example of PHP in HTML, which however someone on 20 June 2005 posted over the previous contents of this page.
<html>
<head>
<title>Counting from x to y</title>
</head>
<body bgcolor="white">
<?php function print_sequence ($start, $stop, $increment) {
if ($start > $stop) {
return(FALSE);
}
elseif ($increment <= 0) {
return(FALSE);
}
else {
for ($i = $start; $i < $stop; $i = $i + $increment) {
print "$i ";
}
}
return(TRUE);
}
?>
<h1>Counting from x to y</h1>
<p>
Counting from 1 to 10 by 1: <?php print_sequence(1, 10, 1)?>
</p>
<p>
Counting from 2 to 20 by 2: <?php print_sequence(2, 20, 2)?>
</p>
</body>
