How can one search for partial strings within an array in PHP?

When searching for partial strings within an array in PHP, you can use the array_filter() function along with a custom callback function. This callback function will check if the partial string is present in each element of the array and return true if it matches. By using array_filter(), you can create a new array containing only the elements that match the partial string. 

<?php
// Sample array
$array = ['apple', 'banana', 'orange', 'grape', 'kiwi'];

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

// Custom callback function to check for partial string match
$filteredArray = array_filter($array, function($element) use ($partialString) {
    return strpos($element, $partialString) !== false;
});

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