You can only use === to test for false. If you try to evaluate TRUE, it will return ELSE or NOTHING.
See below:
// This works:
$mystring = 'abcdefg';
$findme = 'a';
$pos = strpos($mystring, $findme);
if ($pos === false) {
echo "Does not Exist!" ;
}else{
echo "True!!" ;
}
// But THIS does not:
$mystring = 'abcdefg';
$findme = 'a';
$pos = strpos($mystring, $findme);
if ($pos === true) {
echo "True!!" ;
}else{
echo "Does not Exist!" ;
}
