Problems with if equals 0












0















'If greater than 1' works...



if (count($resort_results) > 0 && $resort_results['total'] > 0) :


'If equals to 0' doesn't work...



if (count($resort_results) == 0 && $resort_results['total'] == 0) :


When output of $resort_results is:-



array(2) { ["total"]=> string(1) "0" ["results"]=> array(0) { } }


I'm probably missing the obvious but why can't I say if $resort_results is zero?

This expression can never be true:



count($resort_results) == 0 && $resort_results['total'] == 0


If the $resort_results['total'] key exists, then count($resort_results) must be at least 1 by definition.



If that array is like this, its count is 2.



array(2) { ["total"]=> string(1) "0" ["results"]=> array(0) { } }

//    ^ That's what this 2 means


Maybe you meant



if (count($resort_results['results']) == 0 && $resort_results['total'] == 0)


Just from context I would assume total is a single value and results contains 0 or more results.

If you have your data...



array(2) { ["total"]=> string(1) "0" ["results"]=> array(0) { } }


Then the size of the array is hinted at the start - 2. So when you check 



if (count($resort_results) == 0 && $resort_results['total'] == 0) :


The first part is saying if it contains no values, so why bother checking the value if it has no values!



A more common way is to check if the field is not empty and then check the values...



if ( !empty($resort_results['total']) && $resort_results['total'] == 0) :
