while (list ($key, $val) = each ($_GET)) {     $$key = $val; }  while (list ($key, $val) = each ($_POST)) {    $$key = $val; }

冒泡排序（数组排序）

<?php//算第$w周星期一为几月几日.function w($w,$y){   //$w为第几周;//$y哪一年 $days = date('w',mktime(0,0,0,1,1,$y)); if($days==0){  $a = 24*60*60; }else{  $a = (8-$days)*24*60*60; } $sec = $w*7*24*60*60+mktime(0,0,0,1,1,$y)+$a-7*24*60*60;...

匹配中文字符的正则表达式： [u4e00-u9fa5] 　　

匹配双字节字符(包括汉字在内)： [^x00-xff] 　　

应用：计算字符串的长度（一个双字节字符长度计2，ASCII字符计1）
