Question

Usually I can get away with using something like:

$a = ($condition)? array(1,2,3) : '';

But now I have a method that accepts a multidimensional array and I must pass or not pass one of the arrays conditionally.

$this->mymethod(
    'myarrays'=> array(
        array('key' => 'lang_code'),
        array('key' => 'lang_description'),
        array('key' => 'lang_direction'),
        ($mycondition==true)? array('key' => 'lang_export') : ),
    )
);

Basically, the issue is with the last array passed. And more specifically the ELSE statement in the ternary If operator. It seems that I can’t pass simply a blank space after the : and I can’t pass anything else like FALSE or ” (empty string), because later on in the code the foreach that runs through this array gives errors.

My question is:
How to pass a parameter to a function/method based on a condition?

Answer 1

array_filter(array(
    array('key' => 'lang_code'),
    array('key' => 'lang_description'),
    array('key' => 'lang_direction'),
    $mycondition ? array('key' => 'lang_export') : null),
));

This will remove the null
