What is the best practice for searching for a partial string in an array in PHP?

When searching for a partial string in an array in PHP, the best practice is to use the array_filter function along with a custom callback function that checks if the partial string is present in each element of the array. This approach allows for flexibility in the search criteria and ensures that only matching elements are returned. 

// Array to search
$array = ['apple', 'banana', 'cherry', 'date'];

// Partial string to search for
$partialString = 'an';

// Custom callback function to check if the partial string is present in each element
$filteredArray = array_filter($array, function($element) use ($partialString) {
    return strpos($element, $partialString) !== false;
});

// Output the filtered array
print_r($filteredArray);
