function custom_function()
{
if ($error == 0) {
return true;
} else {
return "Error!";
}
}
if (custom_function() != "Error!") {
echo "Success";
} else {
echo "Error";
}
Also, you could still return false on your custom_function(), if before
the return you $_SESSION['error'] = 'Error!';. Then you could check for
false or true with your if (custom_function()) and echo/unset the
$_SESSION['error'] part.
