In what scenarios would using a foreach loop be more suitable for filtering data in PHP compared to other methods?

Using a foreach loop would be more suitable for filtering data in PHP when you need to apply a custom filtering logic that cannot be easily achieved with built-in array functions like array_filter. Additionally, foreach loops offer more flexibility in manipulating the data during the filtering process. This can be useful when you need to perform complex operations on each element of the array before deciding whether to include it in the filtered result. 

// Example of using a foreach loop to filter data based on a custom condition
$data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

$filteredData = [];
foreach ($data as $value) {
    if ($value % 2 == 0) { // Filter even numbers
        $filteredData[] = $value;
    }
}

print_r($filteredData);
