组合2个数组并在数组PHP中允许相同的值

Question

I have this array:

$title = array('new year', 'cuti bersama', 'cuti bersama');
$date = array('2018-1-1', '2018-1-10', '2018-2-13');

I combined them into

$title_date = array_combine($title, $date);

What i get is only 1 cuti bersama, it has same title but different date. how to allow same title in combined array?

My expected output is like this:

array(
 [new year] => '2018-1-1'
 [cuti bersama] => '2018-1-10'
 [cuti bersama] => '2018-2-13'
);

Answer 1

Since the date is unique you can have it the other way around.

$title = array('new year', 'cuti bersama', 'cuti bersama');
$date = array('2018-1-1', '2018-1-10', '2018-2-13');

$title_date = array_combine($date,$title);

Var_dump($title_date);

And you can use array_filter to find all cuti bersama.

$searchFor = 'cuti bersama';
$filteredArray = array_filter($title_date, function($item) use($searchFor){
    return $item == $searchFor;
});

Var_dump($filteredArray);
