What are some alternative approaches to using preg_match_all with arrays in PHP?

When using preg_match_all with arrays in PHP, the function will only match against the string representation of the array, rather than each individual element. To work around this, you can loop through the array and apply preg_match_all to each element separately. 

// Sample array
$array = ["apple", "banana", "cherry"];

// Regular expression pattern
$pattern = "/[aeiou]/";

// Loop through each element in the array and apply preg_match_all
foreach ($array as $element) {
    preg_match_all($pattern, $element, $matches);
    
    // Output the matches for each element
    print_r($matches);
}
