How to keep only none falsy numbers in an array with PHP

Answer 1

$array = [5, 6, null, "javascript", "", null, 9, null, null, 0, null, 8, 3.14, 85];

// Use array_filter to filter out non-numeric or "falsy" values
$array = array_filter($array, function($value) {
    return is_numeric($value) && $value != 0;
});

print_r(array_values($array)); // Re-index the array to reset keys



/*
run:

Array
(
    [0] => 5
    [1] => 6
    [2] => 9
    [3] => 8
    [4] => 3.14
    [5] => 85
)
