Randomize code

Tanax · 05-05-2008, 07:26 AM

Hi!

How could make a random coded string which has the markup like the one below:

Code:

XXXX-XXX-XXX-XX-XXXX

I understand that I have to use random, or some form of array splits.. but.. how?

Here you go:

PHP Code:


			

<?php

$string = "TEST-Aijnn-Bvvv";

$string = explode('-',$string);

$string = $string[0].'-'.$string[1].'-'.$string[2];

echo $string;
?>

change the string however you want.

Something like this?

PHP Code:


			
$str = 'XXXX-XXX-XXX-XX-XXXX';
echo preg_replace_callback('/X/', create_function('$match', 'return chr(rand(65, 90));'), $str);

Is it possible to also have it with numbers? :O

Sorry, my code wasnt complete enough, here:

PHP Code:


			
<?php



$string = "TEST-Aijnn-Bvvv-66-bb-ff";



$string = explode('-',$string);



$string = soundex($string[0]).'-'.soundex($string[1]).'-'.soundex($string[2]);



// This encodes the pieces between each hyphen, course you can

// always do this with a for loop or something, and have what

// you want



echo $string;

?>

With numbers

PHP Code:


			
<?php 

    $str = 'XXXX-XXX-XXX-XX-XXXX';
    
    echo preg_replace_callback('/X/', create_function('$match', 'return rand(0, 1)? chr(rand(65, 90)) : chr(rand(48, 57));'), $str);

?>

@Orc: your code will generate the same string every time so it isn't that random

By the way, why is this in Absolute Beginners, I thought Tanax was more than a just a Beginner? :P

sjaq · 05-05-2008, 09:00 AM

@Orc I think this is pretty basic stuff so it belongs in the Beginners section

heh. what do you mean by basic?

Orc · 05-05-2008, 09:06 AM

BY the way, heres another method

PHP Code:


			
<?php

$array = array('test','test','test','test','test','test');
$string = implode('-',$array);


echo $string;



?>

Works like a charm! Thanks

@Orc- Well.. erh.. I'm farily good. But since this is really basic stuff, it belongs in the beginners section ;P
I mean, it's not really any "advanced" functions, it's just basic random and preg replaces..

Orc I think you don't get the thing he's trying here, he wants to have random strings not the same string every time you run the script.

I know that, but Im too lazy to put in the code, as I said the code is incomplete, now shush.
