[RESOLVED] Problem with if conditions

[mikawhat]

I have this stupid problem and i can't figure out what's wrong. When i'm trying to delete any of the categories i get the message 'The specific category cannot be deleted.' even if the category's $s value is N. When i change the condition to if ($s == 'Y') it deletes everything, even those with $s value = Y.

$check = @mysql_query ("SELECT standard FROM category WHERE id='$id'");
		$row = mysql_fetch_array ($check);
		$s = $row['standard'];
		if ($s = 'Y') {
			echo '<p>The specific category cannot be deleted.</p>';
			include ('includes/footer.inc.php');
			exit();
		} else {
		$delete = @mysql_query ("DELETE FROM category WHERE id='$id'");
			echo '<p>Category deleted succesfully.</p>';
			include ('includes/footer.inc.php');
			exit();
		}

What's wrong with this condition?

This is always true:

$s = 'Y'

this is an assignment operators, if u need to check if $s is 'Y' u need comparison operators

$s == 'Y'

Comparison Operators
Assignment Operators
In your case u should use string comparation:
stristr()
String functions

Ex.

if(stristr($s,'Y')===true)

I use stristr because is case insensitive...

OK thank you.
I used $a == $b and it seems to be working.
