generate random string

[srcfresno]

So I found this code from someone else on here who posted about creating a random string. I've copied the code for myself but when I upload php page to my server and view source... there is no php code. Essentially, i see no randomly generated text. what am i missing?

 

<?php
function genRandomString() {
    $length = 5;
    $characters = array_merge(range(0,9),range('a','z'),range('A','Z'));
$string = "";	
    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, count($characters)-1)];
    }
    return $string;
}
?>

Post the code in which you call the function also.

can you be a little more descriptive please

You can see only HTML and javascript when you view source the page in the browser. PHP is a server side scripting language. PHP code can't be shown

Post the code where you call the function genRandomString().

Post the code that you've written that makes a call to the function above, for the purpose of generating the output.

excuse my ignorance... so like that

 

<?php
function genRandomString($length, $characters, $string) {
    $length = 5;
    $characters = array_merge(range(0,9),range('a','z'),range('A','Z'));
$string = "";	
    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, count($characters)-1)];
    }
    return $string;
}
?>

then use

 

echo($genRandomString(5, "a-z");

That function seems poorly written.

 

Use something like this

<?php 

$characters = array_merge(range(0,9),range('a','z'),range('A','Z'));
shuffle( $characters );
// Where 5 is legnth of string
echo implode( '', array_slice($characters,0,5) );

?>

that totally worked, thank you.
