Not true, That is the purpose of isset()
<?php
$myVar = 0;
if (isset($myVar)) {
// will execute
}
?>
<?php
if (isset($myVar)) {
// $myVar has never been set
// will not execute
}
?>
<?php
$myVar = 0; // zero means FALSE, any other value is good (positive or
negative)
if ($myVar) {
// $myVar is considered set by isset
// however it evaluates to zero,
// and will therefore not execute
}
?>
