随机生成含有大小写字母，数字的字符串。可以修改定制。$str = null;<br>
$num = 10;// 字符串长度<br>
$strPol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz";//如果不需要小写字母，可以把小写字母都删除<br>
$max = strlen($strPol)-1;<br>
<br>
for($i=0;$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<br>
}<br>
echo $str;
