Are there any best practices to follow when searching for a word in an array in PHP?

When searching for a word in an array in PHP, it is important to use the array_search() function, which searches for a given value in an array and returns the corresponding key if found. It is also a good practice to use strict comparison (===) to ensure the search is done based on both value and data type. 

$words = array("apple", "banana", "cherry", "date");
$search_word = "banana";

$key = array_search($search_word, $words, true);

if ($key !== false) {
    echo "The word '$search_word' was found at index $key.";
} else {
    echo "The word '$search_word' was not found in the array.";
}
