Saving result of function without being echoed

team_lh_Max

HEy there,

I am trying to save the function "rand(1, 1000000)" in a variable but when I am for example trying

$randomnumber = rand(1, 1000000);

it is executing it right ahead while when i try

$randomnumber = "rand(1, 1000000)";

$randomnumber = 'rand(1, 1000000)';

It is saving rand(1, 1000000) as variable.

But what I need is a variable saving the result of rand(1, 1000000) so the number does not change either.

Any ideas how I would do this?

Thank you in advance
Max

Not sure how you are using this function because it will return a different RANDOM each time the script is run you will need to save that as a SESSION or possibly in the database and then compare it to an input provided by the user.

This code (run it two or three times to see the different values it produces

<?php 
$random=rand(1, 1000000);
echo $random;
?>

yes but what i need is a random generated number saved in a variable which will not change anymore.

You could use a session key for this.

//Start session when needed
if(!session_id()) {
session_start();
}

// Calculate a random number
$randomnumber = rand(1, 1000000);

// If no random number in session key "random" yet, save current $randomnumber as session key "random"
if(!isset($_SESSION['random'])) {
$_SESSION['random'] = $randomnumber;
} else {
// If random number in session key, echo it.
echo $_SESSION['random'];
}

Ok thanks for that but I found an easier way for my way of using it.

I simply md5 the lastname and use that as activation code.

Still thank you guys a lot for your great help apreciated a lot!
