Is RegEx a viable option for searching for values in an array in PHP, and if so, how can it be implemented?

Using regular expressions (RegEx) in PHP is a viable option for searching for values in an array. You can use functions like preg_grep() to search for a specific pattern within an array. Simply provide the pattern you want to search for as the first argument and the array to search in as the second argument. This function will return an array of elements that match the pattern. 

// Sample array to search
$array = array('apple', 'banana', 'cherry', 'date', 'fig');

// Search for values containing the letter 'a'
$results = preg_grep('/a/', $array);

// Output the results
print_r($results);
