Rand()

[Drezard]

Hello, I want to use the rand() function for a variable.

 

So like:

 

Code:

 

<?php

number = rand();

?>

 

 

But it gives me these errors:

 

Quote:

 

 

Parse error: parse error, unexpected '=' in C:\Program Files\xampp\htdocs\test\rand.php on line 3

 

 

Whats wrong or how can i do this?

you have a lil error in there

 

<?php

number = rand();

?>

 

should be

 

<?php

$number = rand();

?>

Or if you want a random number between x and y, where x is starting number and y is ending number:

 

$number = rand(1,50);

 

In this example x=1 and y=50.  This will generate a random number between 1 & 50.

Off Topic: You can get a random number from an existing array too.

<?php
$array = array('thing1','thing2','thing3');

$value = array_rand($array);

echo $array[$value];

 

This will get a random image from a directory using the same concept:
