In PHP, how can arrays be efficiently manipulated to remove specific elements based on matching values in different arrays?

When removing specific elements from an array based on matching values in different arrays, one efficient way to do this is by using array functions like array_diff() or array_filter(). These functions allow you to compare values in arrays and remove elements that match specific criteria. By using these functions, you can manipulate arrays efficiently without needing to loop through each element manually.

// Sample arrays
$array1 = [1, 2, 3, 4, 5];
$array2 = [2, 4];

// Remove elements from $array1 that are present in $array2
$result = array_diff($array1, $array2);

print_r($result);
