What do you get if you do:
if (isset($a)) {
print '$a is set';
} else {
print '$a is not set';
}
$a = "";
if (isset($a)) {
print '$a is set';
} else {
print '$a is not set';
}
You get:
F:\>c:\PHP\php -f test.php
$a is not set
$a is set
F:\>
Why? Becasue pointing to an empty string
is not the same as having no pointer at all.
Does this solve your problem?
