Random string are often used in web application to assign records a unique random key. Here is very useful random string generator function that allows you generate random string of any length.
Just call the function and pass a length. If you omit length parameter it will generate a 10 characters long alphanumeric string.
function generate_string($length=10){
$chars = array_merge(range(0, 9), range('A', 'Z'), range('A', 'Z'));
shuffle($chars);
$string = implode(array_slice($chars, 0, $length));
return $string;
}

Hello Tahir,
I think the third rang(‘A’, ‘Z’) should be rang(‘a’, ‘z’), otherwise, your generated string will contains no lower letters.

Yes, you are right but I intentionally capitalized, but you can change their case if you need both upper and lower case letters.
