How can the use of array_to_json function impact the performance of a PHP search function?

Using the array_to_json function in a PHP search function can impact performance by increasing the amount of data being processed and potentially slowing down the search operation. To improve performance, it's recommended to only convert the necessary data to JSON format when needed, rather than converting the entire array. 

// Example of converting only necessary data to JSON in a PHP search function
$searchResults = []; // Array of search results

// Iterate through search results and only convert necessary data to JSON
foreach ($searchResults as $result) {
    $jsonData = json_encode([
        'id' => $result['id'],
        'name' => $result['name'],
        'description' => $result['description']
    ]);
    
    // Use $jsonData as needed
}
