If I have an array full of information, is there any way I can a default for values to be returned if the key doesn't exist?
function items() {
return array(
'one' => array(
'a' => 1,
'b' => 2,
'c' => 3,
'd' => 4,
),
'two' => array(
'a' => 1,
'b' => 2,
'c' => 3,
'd' => 4,
),
'three' => array(
'a' => 1,
'b' => 2,
'c' => 3,
'd' => 4,
),
);
}
And in my code
$items = items();
echo $items['one']['a']; // 1
But can I have a default value to be returned if I give a key that doesn't exist like,
$items = items();
echo $items['four']['a']; // DOESN'T EXIST RETURN DEFAULT OF 99
