change value of 0

[th1chsn]

I want to check a variable to see if it's a zero and if it is change it to a 1. But there must be something wrong with my code because it isn't changing the value.

$id = 0;
if ($id = 0) {
 $id = 1;
}
echo $id;

Can someone help me figure out what I'm doing wrong?

Figured it out. You guys are good. You don't even have to answer the posts :)

if ($id == '0') {
 $id = 1;
}

LOL!
Yep, a common mistake and easy to overlook!

Still not quite right. The quotes around the zero, while they do work due to loose typing, are causing the zero to be a string.
