What are some alternative methods to remove elements from an array in PHP besides using unset?

When removing elements from an array in PHP, besides using unset, you can also use array_splice() or array_filter() functions. array_splice() allows you to remove a portion of an array and replace it with something else if needed. array_filter() can be used to remove elements based on a specified condition.

// Using array_splice() to remove elements from an array
$array = [1, 2, 3, 4, 5];
array_splice($array, 2, 1); // Removes element at index 2
print_r($array);

// Using array_filter() to remove elements from an array based on a condition
$array = [1, 2, 3, 4, 5];
$array = array_filter($array, function($value) {
    return $value != 3; // Removes element with value 3
});
print_r($array);
