Generator fail.

[President Obama]

Had a crack at making my own generator which makes some jumble 32 characters long with letters and numbers. In logic it seemed fine to me. It practice it just does nothing.

function generate(){
$abc = array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"); 
$num = array("0", "1", "2", "3", "4", "5", "6", "7", "8", "9");
$result = ""; 

for ($i = 0; $i < 32; $i++){
	$bool = rand(0,1);
	if ($bool = 1) {
		$result . $abc[rand(0,25)];	
	} else {
		$result . $num[rand(0,9)];
	}
}
echo $result;
}

Is a post on that here, not to mention a few others in the forums dealing with random generation and from arrays/lists.

<?php
   $length = 32;
    $characters = '0123456789abcdefghijklmnopqrstuvwxyz';
    $string = '';    
    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, strlen($characters) -1 )];
    }
    echo $string;
?>

or a function

 

<?php
function generateString($length) {
    $characters = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
    $string = "";    
    for ($s = 0; $s < $length; $s++) {
        $string .= $characters[mt_rand(0, strlen($characters))];
    }
    return $string;
}

//usage
$randomstring = generateString(32);//define amount of characters
echo $randomstring;
?>

oops forgot to add the -1 to define

also added more numbers to offset the letters more

 

<?php
function generateString($length) {
    $characters = "0123456789abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    $string = "";    
    for ($s = 0; $s < $length; $s++) {
        $string .= $characters[mt_rand(0, strlen($characters)-1)];
    }
    return $string;
}

//usage
$randomstring = generateString(32);//define amount of characters
echo $randomstring;
?>

You can even just pull a random md5 if wanted, and do range for length 1 to 32

 

<?php
function uniqueString($length) {
$string = substr(md5(uniqid()), 0,$length);
return $string;
}
//usage
$random_string = uniqueString(10);//min 1 to max 32 for length
echo $random_string;
?>

ok Thanks guys. I'm always learning new things. This random stuff is a bit tricky to me.
