How can beginners effectively utilize functions in PHP for tasks like searching for specific data?

To effectively utilize functions in PHP for tasks like searching for specific data, beginners can create a custom function that takes in the data to search and the search query as parameters. Within the function, they can iterate through the data using loops or array functions to check for matches with the search query and return the results. 

function searchSpecificData($data, $searchQuery) {
    $results = array();

    foreach ($data as $item) {
        if (strpos($item, $searchQuery) !== false) {
            $results[] = $item;
        }
    }

    return $results;
}

// Example usage
$data = array("apple", "banana", "cherry", "date");
$searchQuery = "an";
$searchResults = searchSpecificData($data, $searchQuery);

print_r($searchResults); // Output: Array ( [0] => banana )
