In PHP, how can a search for entries in an array with composite keys be elegantly solved?

When searching for entries in an array with composite keys in PHP, one elegant solution is to use array_filter() with a custom callback function. This function can iterate through the array and check if the composite key matches the search criteria. The callback function should return true for matching entries and false for non-matching entries. 

// Sample array with composite keys
$array = [
    ['key1' => 'value1', 'key2' => 'value2'],
    ['key1' => 'value3', 'key2' => 'value4'],
    ['key1' => 'value5', 'key2' => 'value6']
];

// Search criteria for composite keys
$searchKey1 = 'value3';
$searchKey2 = 'value4';

// Custom callback function for array_filter
$result = array_filter($array, function($entry) use ($searchKey1, $searchKey2) {
    return ($entry['key1'] == $searchKey1 && $entry['key2'] == $searchKey2);
});

// Output the matching entries
print_r($result);
