63 Tips for speeding up PHP
<html>
<body>
<p>Here are Webber’s points:</p>
<ul>
<li>If a method can be static, declare it static. Speed improvement is by a factor of 4.</li>
<li>echo is faster than print.(<em>* compare with list from phplens by John Lim</em>)</li>
<li>Use echo’s multiple parameters instead of string concatenation.</li>
<li>Set the maxvalue for your for-loops before and not in the loop.</li>
<li>Unset your variables to free memory, especially large arrays.</li>
<li>Avoid magic like __get, __set, __autoload</li>
