$_GET variable goes to 0

[visionaire]

Hello all,

 

I am terribly confused about the following code, for some reason $tourn keeps going back to 0 for no reason!

 

This code:

<?php

include 'header.php';

$tourn = $_GET['extourn'];

echo "first ".$tourn."<br />";

if($tourn=0){
echo "tourn1 is ".$tourn."<br />";
}

else{
echo "tourn2 is ".$tourn."<br />";
}

?>

returns this:

first 4

tourn2 is 0

 

While tourn2 should return 4 as well. I have tried a million different versions, including switches and everything and just can't understand it. Please help!

You set it to zero here: if($tourn=0){  - You need to use a comparison operator == rather than an assignment operator =

if( $tourn == 0 ) {

Exactly what Pikachu2000 said... I think you can also use the === operator for an exact type match.
