Are there any built-in functions in PHP that allow for wildcard-based removal of array elements?

To remove array elements based on a wildcard pattern in PHP, you can use a combination of array_filter() and a custom callback function that checks if the array key matches the wildcard pattern. The callback function can use a regular expression to match the wildcard pattern and return true for elements that should be kept in the array. 

// Example PHP code to remove array elements based on a wildcard pattern
$array = ['apple', 'banana', 'cherry', 'date', 'grape'];

$pattern = '/^b/'; // Remove elements that start with 'b'

$result = array_filter($array, function($key) use ($pattern) {
    return !preg_match($pattern, $key);
}, ARRAY_FILTER_USE_KEY);

print_r($result);
