Creating a random number generator

[bobsci]

Hi all...

 

I just wanted to do something really simple... i want php to echo 7 random numbers ie: 4528765. using the values 123456789. How do i go about it? thanx

my guess is use mt_rand(min, max)

 

either use mt_rand() for each of the 7 digits, then combine them together, or use 1 mt_rand() for the whole thing (ie. mt_rand(1000000,9999999), if it allows numbers that large). I\'m a n00b myself, so don\'t assume this is the best way, because most likely it isnt. This should work though:

 

[php:1:c904f12a77]<?php

$array = array(mt_rand(1, 9), mt_rand(1, 9), mt_rand(1, 9), mt_rand(1, 9), mt_rand(1, 9), mt_rand(1, 9), mt_rand(1, 9));

$random = implode(\"\",$array);

echo $random;

?>[/php:1:c904f12a77]
