Isn't this problem solvable with just a "User Space" function?
<?php
error_reporting(E_ALL);
function ifsetor(&$variable, $alternate = NULL){
if(isset($variable)){
$tmp = $variable;
echo('<p>$variable exists.</p>');
}
else{
$tmp = $alternate;
echo('<p>no $variable here.</p>');
}
return $tmp;
}
// no errors thrown ...
$nonexistent = ifsetor($nonexistent);
ifsetor($randomNonexistent);
if($nonexistent !== NULL)
echo('<p>$nonexistent is NOT NULL</p>');
else
echo('<p>$nonexistent is NULL</p>');
?>
Because, as Derick Rethans mentioned, arguments passed by
reference will not trigger the Undefined (variable | index)
Notice at the point of the function call, and also PHP's C++
style default arguments providing the alternate value, surely
the above code would suffice?
Apologies if I've completely misunderstood (with certainty a
non-zero probability)...
