Conditional statement

[holowugz]

Hell again guys,

ok this is my conditional statementL

if($class !== 7) {
header("Location: ". $redirectSuccess);
exit;
}

basically i am saying if $class is not 7 follow that instruction but it cycles through the statement anyway, what i am testing it on the vlaue of class is DEFINITELY 7

any ideas?

get rid of the second equals sign and you should be all set.

...? , i thought == is the comparison operator and = was the operator to set something to something:

i.e $var = 7 (Is set To)
if($var == 7) (if Var equals 7)

does it differ in an if statement then?

Yes, that is true, but we're looking at conditional operators:
== equal values
!= not equal values
=== equal types
!== not equal types

The difference here is usefull when comparing a return of "false" to a return of 0
This code [code]<?php $x = 0;
if ($x == false) echo "true"; else echo "false" ?>[/code]
will print "true", while this code
[code]<?php
$x = 0;
if ($x === false)echo "true"; esle echo "false" ?>[/code]
will print "false".

The first is comparing the values " 0 == 0" (false has the value of 0)
The second is comparing types " integer != boolean "
