What are alternative methods to using for loops and count() for array manipulation in PHP, especially when removing substrings?

When removing substrings from an array in PHP, using for loops and count() can be inefficient and cumbersome. An alternative method is to use array_filter() in combination with a custom callback function that checks for the substring to be removed. This allows for a more concise and efficient way to manipulate arrays without the need for explicit looping. 

// Example code snippet using array_filter() to remove substrings from an array
$array = ['apple', 'banana', 'orange', 'kiwi', 'grape'];
$substringToRemove = 'an';

$result = array_filter($array, function($item) use ($substringToRemove) {
    return strpos($item, $substringToRemove) === false;
});

print_r($result);
