[SOLVED] create a random number at a certain length

[ballhogjoni]

I want to create a random number that is 10 digits long. I was looking at rand but that doesn't give me exactly what I want. How do you do that?

for ($x = 0; $x < 10; $x++) {
   $string .= rand(0,9);
}

What's wrong with:

<?php
$str = rand(1000000000,9999999999);
echo $str;
?>

Because more than likely the highest number rand() can return is 2,147,483,647 since it generates an integer. 

 

can do

 

echo getrandmax();

 

to see what the highest number rand() will generate on your system.
