Ahh.. the trick question. hah.. Ok, let me see if I remember this (although it doesn't seem to follow the logic in my head.. I know someone else will explain it better but let me take a crack at it):
When comparing a two different variable types that PHP thinks it knows how to compare, it will try. In this case, I believe the 'A' gets converted to a true/false type thing (0 or 1).. although I thought it'd convert to a 1 so you'd have if (1 == 0) which would be false. At any rate, something like that is happening and it's comparing values that you don't think you're comparing. Try using the triple equal sign operator (===) instead of the dobule (==). This forces PHP to not do the conversion.. to compare EXACT values. Using === means that 0 does not equal '0' because 0 is an int and '0' is a string. Someone else will give a better explaination soon, just wanted to give you something so you weren't stuck/frustrated/etc for too long. -TG = = = Original message = = = Could anyone tell me why this code echos? <?php $value = 0; $curval = 'A'; if ($value == $curval) echo "WTH, Over<br>"; ?> ___________________________________________________________ Sent by ePrompter, the premier email notification software.
