How to generate a string that

Anon

Which PHP function can generate a string randomly that is made of only letters and numbers(a-zA-Z0-9)?
for example: StRiNG123

Thank you!

Try this one out!

function randString ($pass_len = 10){
$allchars =
'abcdefghijklnmopqrstuvwxyzABCDEFGHIJKLNMOPQRSTUVWXYZ0123456789';
$string = '';

mt_srand ((double) microtime() * 1000000);

for ($i = 0; $i < $pass_len; $i++) {

$string .= $allchars{mt_rand (0,strlen($allchars))};
}

return $string;
}

function random_string($length)
{
$rand_str="";
for($i=0; $i<$length; $i++)
{
$rand_ind=mt_rand(1, 3);
switch($rand_ind)
{
case 1:
$rand_str.=rand(0, 9);
break;

case 2:
$rand_str.=chr(rand(65, 90));
break;

case 3:
$rand_str.=chr(rand(97, 122));
break;
}
}
return $rand_str;
}
