Are there any specific PHP functions or techniques that are recommended for searching JSON data?

When searching JSON data in PHP, the `json_decode()` function can be used to convert a JSON string into a PHP array or object. Once the JSON data is in a PHP-friendly format, array functions such as `array_search()` or `array_filter()` can be used to search for specific values or elements within the data. 

// Sample JSON data
$jsonData = '{"name": "John", "age": 30, "city": "New York"}';

// Convert JSON data to PHP array
$dataArray = json_decode($jsonData, true);

// Search for a specific value in the JSON data
$searchKey = 'name';
if(array_key_exists($searchKey, $dataArray)) {
    echo $dataArray[$searchKey];
} else {
    echo "Key not found";
}
