variables

This is the var_dump:

object(stdClass)#27 (8) { 
    ["SETTING_ID"]=> string(2) "25" 
    ["SETTING_SOURCE"]=> string(2) "XV" 
    ["SETTING_FLEET"]=> string(3) "313" 
    ["SETTING_EXAM"]=> string(1) "A" 
    ["SETTING_HIDE"]=> string(1) "0" 
    ["SETTING_THRESHOLD"]=> string(1) "0" 
    ["SETTING_COUNT"]=> string(8) "POSITIVE" 
    ["SETTING_USAGE"]=> string(7) "MILEAGE" 
}

The variable I am testing is SETTING_HIDE. This is being pulled from MySQL using the Code igniter framework. I don't know if it is just me being thick after a rather long day at work or what, but no matter what value the variable holds, any if statement made against it returns true, even when typecast as a boolean or a direct string comparison, ie. == "0" or == "1".

Anyone with a fresh pair of eyes care to make me feel silly!?! :)

Just to clarify:

Have tried the following:

if($examSetting->SETTING_HIDE == "1") {  $showOnABC = "checked=\"checked\""; } 
if((bool)$examSetting->SETTING_HIDE) {   $showOnABC = "checked=\"checked\""; }



if($examSetting->SETTING_COUNT == "POSITIVE") further on in my code works perfectly.
