how to have 20 "rand" in 1 string?

[Driiper]

Hello! i creating a game "School project" and then i was wondering how can i have 1 string with rand() instead of 20..

 

if i have just 1 rand the random number is the same :S

 

Any ideas?

 

Thanks

not sure what you want to do, but you can set rand to give a random number between 2 numbers.

 

$random = rand(0, 100);

 

now you will get a random number between 0 and 100.

 

If that is not what you were looking for then please explain a little better. Or give an example of what you want to accomplish.

I think what you want is one string that contains the output of rand() run 20 times?

$string = '';
for ($x=0; $x<20; $x++){
  $string .= rand(); // concatenate onto string the result of rand()
}
echo $string;

@ucffool - Won't work like that... From the manual:

 

If called without the optional min , max  arguments rand()  returns a pseudo-random integer between 0 and RAND_MAX

 

 

This should work:

<?php

$string = '';
for ($x=0; $x<20; $x++)
  $string .= rand(0,9); // concatenate onto string the result of rand()
echo $string;

?>

 

 

Orio.

Assuming he is looking for 1 number only. I realize that's the way rand() will work, I was just getting the bigger concept across.

Either way, I suppose it is good someone clarified.

I would recommend mt_rand() or mt_rand(0,9) instead.
