复制代码 代码如下:

function randStr($len)

{

$chars='ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz'; // characters to build the password from

$string='';

for(;$len>=1;$len--)

{

$position=rand()%strlen($chars);

$string.=substr($chars,$position,1);

}

return $string;

}

echo randStr(10)."<br>";
