Are there best practices for optimizing search functions in PHP to prevent long execution times?

When optimizing search functions in PHP to prevent long execution times, it is important to utilize efficient algorithms and data structures. One common approach is to use indexing techniques to quickly locate the desired data. Additionally, limiting the amount of data being searched through and optimizing database queries can also help improve performance. 

// Example of optimizing search function using indexing

// Create an index array for faster searching
$index = [];
foreach ($data as $item) {
    $index[$item['id']] = $item;
}

// Search function using index
function searchById($id, $index) {
    if (isset($index[$id])) {
        return $index[$id];
    } else {
        return null;
    }
}

// Example usage
$result = searchById(123, $index);
