Php filtering array

Question

I have to filter an array for PrestaShop. I have some raw data, but I have to filter this. So I have some inputs for search in raw data and I try in many ways but my boss still says there is a better way. I don't get this so I need help.

<?php 
// Raw data
$data = array(
    array('id' => 1, 'name' => "Andrei", "time" => 3),
    array('id' => 5, 'name' => "David", "time" => 62),
    array('id' => 8, 'name' => "Igor", "time" => 12),
    array('id' => 4, 'name' => "Jack", "time" => 3),
);
// These are condition for filter my $data 
// In this condition i want filter my $data by name and time
$conditions = array('id' => null, 'name' => "David", 'time' => "3");
?>

The question is what is the best way or method for filter for all combination of my $condition?

You should show the "many ways" that you have tried. You should also show what the expected result is from the above sample. — Patrick Q

@PseudoAj How is that related? This is an indexed array, not an associative array. — Barmar

You should look into array_filter using a callback.

array_filter($data, function ($item) use ($conditions) {
    return $item['id'] === $conditions['id'] || $item['name'] === $conditions['name'] || $item['time'] === $conditions['time'];
}

You will want to tweak the return's verification depending on your intended filtering.

You need to add use($conditions) to the function so that it can access the variable.

It’s been a solid while since I have used PHP (mostly a JavaScript developer now) and I always forgot to do that, even when I was actively using it. Thanks!
