PHP Random String Generator Function Programming Tutorial

Listening Video

Learn to program a PHP random string generator that can be as long as you specify. We demonstrate how to then make your script modular in order for it to be reusable, external and dynamic. Splitting (str_split) any string gives you an array from that string, then you can pluck out elements of that array (array_rand) within a for loop in order to return a randomly generated string of characters of any length.

Lesson Code

<?php

function randStrGen($len){

$result = "";

    $chars = "abcdefghijklmnopqrstuvwxyz$_?!-0123456789";

    $charArray = str_split($chars);

    for($i = 0; $i < $len; $i++){

    $randItem = array_rand($charArray);

    $result .= "".$charArray[$randItem];

    }

    return $result;

}

?>

<?php

// Usage example

$randstr = randStrGen(200);

echo $randstr;

?>
