Hi, so I took PHP a while back, but a lot of it never really stuck.

I remember something about “$variable = value” versus “$variable == value” and that you should never, never, never confuse the two…but I can’t remember why.

Does anybody have an explanation of this for me?

Thanks!

Assignment versus comparison.

$a = 42
$b = '42'
$a == $b     // true (after type juggling)
$a === $b    // false (not identical)
