$status = 'all';
$order = array(); $field = 'priority';
if($status == 'all'){ $order = array_keys($list); }else { foreach ($list as $key => $item) { if ($item['complete'] == $status) { $order[] = $key; } } }
/////////////////// $status variable is string and $item['complete'] is boolean. How the compare here will work!! They are not same type!! if ($item['complete'] ===$status) { $order[] = $key; }

Waqar Mohammad provides the solution which is to change the condition of the first if to ($status === "all") instead of ($status == "all").
The reason for this is further explained by Alexandre Babeanu who explains the difference between == and === in php when comparing boolean and strings. He states "When status is set to true then status it is set as a boolean. when comparing a boolean to a string with == php will look either for an empty string (false) or for not an empty string (true)."
Their answers should provide you with the information you seek and deserve all credit.
