Here is a PHP interpreter on a web page. I wrote it to help me learn PHP
and it was very helpful. Just copy the code below to a web page, like
"eval.php".
WARNING! If you put this code on a public server, you should change the
hardcoded password (BULLDOG) to something non-obvious, otherwise a hacker
could use it to mess with your server.

$ex = stripslashes($expr).";";
echo "eval('<b> $ex </b>')<p>";
eval($ex);
if (gettype($r)=='array') {
echo "\$r is an array... ";
foreach ($r as $k => $i) echo "<br>$k = $i";
} else echo "\$r is $r ";
}
?>
