[RESOLVED] Simple if else statement not working?

[iBuddy]

<?
#1 = ON
$interstitial_status = 0;

if ($interstitial_status = 1) {
echo "Interstitials are currently: On";
}else{
echo "Interstitials are currently: Off";
}
?>

How come this doesnt work? I have the variable set to 0 and it keeps saying its on when I run the page?

ahhhh I figured out what it was. I need two == signs. Why is that? How do I know when to put 1 = sign or 2?

[dotnotwhat]

A single = is used for assigning a value to a variable.

Double == is used for testing equality of two values.

So use = whenever you want to assign a value to a variable and use == whenever you are testing the value of a variable in an expression.
