How can PHP be used to read and write the source code of a webpage to a file or database?

To read and write the source code of a webpage to a file or database using PHP, you can use the file_get_contents() function to read the source code of the webpage and then use file_put_contents() function to write the source code to a file. If you want to store the source code in a database, you can use SQL queries to insert or update the source code in a database table. 

// Read the source code of a webpage
$url = 'https://www.example.com';
$sourceCode = file_get_contents($url);

// Write the source code to a file
file_put_contents('source_code.html', $sourceCode);

// Connect to a database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Insert or update the source code in a database table
$sql = "INSERT INTO source_code_table (source_code) VALUES ('$sourceCode')";
$conn->query($sql);

// Close the database connection
$conn->close();
