ToonMariner Posted September 16, 2009 Share Posted September 16, 2009 you have SET it! isset will check to see if the given argument is set. if ((bool)$testObj->testVar === false) is more like what you are after.

jonniejoejonson Posted September 16, 2009 Author Share Posted September 16, 2009 That will be the answer... thanks... Can i ask one more question... what is the difference between === and == thanks J Quote Link to comment https://forums.phpfreaks.com/topic/174451-solved-class-set-varfalse/#findComment-919457 Share on other sites More sharing options...
Zane Posted September 16, 2009 Share Posted September 16, 2009 === means that they are equal AND they are the same type... like...for instance..a string or integer for example: $thevar = "42"; $thevar2 = 42; $thevar === $thevar2 would be false...because the first one is a string, while this next one is true $thevar == $thevar2 /// TRUE Quote Link to comment https://forums.phpfreaks.com/topic/174451-solved-class-set-varfalse/#findComment-919462 Share on other sites More sharing options...
