What are some strategies for efficiently parsing and extracting relevant data from the results of HTTP requests in PHP before storing them in a database?

When parsing and extracting relevant data from the results of HTTP requests in PHP before storing them in a database, it is important to use built-in PHP functions like json_decode or SimpleXMLElement to handle different data formats. Additionally, regular expressions can be used to extract specific information from the response content. It is also recommended to sanitize and validate the extracted data before storing it in the database to prevent SQL injection attacks. 

// Example code snippet for parsing and extracting relevant data from HTTP response in PHP

// Make an HTTP request
$response = file_get_contents('http://example.com/api/data');

// Parse the JSON response
$data = json_decode($response, true);

// Extract relevant data
$extractedData = $data['key'];

// Sanitize and validate the extracted data
$cleanData = filter_var($extractedData, FILTER_SANITIZE_STRING);

// Store the data in the database
// $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
// $stmt = $pdo->prepare("INSERT INTO mytable (data) VALUES (:data)");
// $stmt->bindParam(':data', $cleanData);
// $stmt->execute();
