How can PHP beginners effectively manage and manipulate text content stored in a database?

To effectively manage and manipulate text content stored in a database using PHP, beginners can use SQL queries to retrieve, update, and delete text data. They can also use PHP functions such as mysqli_real_escape_string() to prevent SQL injection attacks and htmlspecialchars() to prevent cross-site scripting attacks when displaying text content on a webpage. 

// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Retrieve text content from the database
$query = "SELECT text_content FROM table_name WHERE id = 1";
$result = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($result);
$text_content = $row['text_content'];

// Update text content in the database
$new_text_content = "New text content";
$new_text_content = mysqli_real_escape_string($connection, $new_text_content);
$update_query = "UPDATE table_name SET text_content = '$new_text_content' WHERE id = 1";
mysqli_query($connection, $update_query);

// Delete text content from the database
$delete_query = "DELETE FROM table_name WHERE id = 1";
mysqli_query($connection, $delete_query);

// Close the database connection
mysqli_close($connection);
