PHP生成随机字符串
<?php class RandChar{ function getRandChar($length){ $str = null; $strPol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz"; $max = strlen($strPol)-1; for($i=0;$i<$length;$i++){ $str.=$strPol[rand(0,$max)];//rand($min,$max)生成介于min和max两个数之间的一个随机整数 } return $str; } } $randCharObj = new RandChar(); echo $randCharObj->getRandChar(5); ?>
