How can SQL be integrated effectively with PHP to manage timestamps for content?

To manage timestamps for content in a PHP application, you can use SQL queries to store and retrieve timestamp values from a database. You can use the SQL `TIMESTAMP` data type to store timestamps in a standardized format. To integrate SQL effectively with PHP, you can use PHP's `mysqli` or `PDO` extension to connect to the database, execute SQL queries, and handle timestamp values. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Insert a new record with a timestamp
$content = "New content";
$timestamp = date('Y-m-d H:i:s');
$sql = "INSERT INTO content (content, timestamp) VALUES ('$content', '$timestamp')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// Retrieve records with timestamps
$sql = "SELECT * FROM content";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Content: " . $row["content"]. " - Timestamp: " . $row["timestamp"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
