| <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> |
