A nice function to generate a random string, using any character:
function generateRandStr($length){
$randstr = "";
for($i=0; $i<$length; $i++){
$randnum = mt_rand(0,61);
if($randnum < 10){
$randstr .= chr($randnum+48);
}else if($randnum < 36){
$randstr .= chr($randnum+55);
}else{
$randstr .= chr($randnum+61);
}
}
return $randstr;
}
Simply use:
generateRandStr(10);
Sample output: $%29zon(4f
