PHP is screwed up on my machine now

[Anon]

Everything worked fine until today. Now simple "if" statements dont work correctly. This is a sample....

<?php
$firstvariable=0;
$secondvariable=0;
if ($secondvariable=1){
$firstvariable=1;
}
echo $firstvariable;
echo $secondvariable;
?>

Clearly both variables should be echoed as "0" but they both echo as "1".

All of my if statements are coming up as true no matter what they test for.

use two '=' in an if statement:

i.e:

<?php
$firstvariable=0;
$secondvariable=0;
if ($secondvariable==1){
$firstvariable=1;
}
echo $firstvariable;
echo $secondvariable;
?>

Thanks, I am retarded!
