strtr与str_replace函数性能，很简单的一个测试，只是简单的测下，供参考，代码如下：

<?phprequire_once('Timer.php');$target = 'qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./qwertyuiop[]asdfghjkl;\'zxcvbnm,./';$count = isset($argv[1]) ? (int)$argv[1] : 1;$needle = 'vb';Timer::getInstance()->begin();for($i = 0; $i < $count; $i++) {strtr($target, $needle, '*');}echo "strtr exec {$count} times used time: " . Timer::getInstance()->end()->gone() . " sec.\n";//----------------------------------------------------------------------------------------------Timer::getInstance()->begin();for($i = 0; $i < $count; $i++) {str_replace($needle, '*', $target);}echo "str_replace exec {$count} times used time: " . Timer::getInstance()->end()->gone() . " sec.\n";

结果如下：

那个正则替换的那个就不测了，应该是赶不上这两个的。
