Is there a more efficient way to delete values from a column in a database using PHP?

When deleting values from a column in a database using PHP, one efficient way is to use a SQL DELETE query with a WHERE clause to specify the condition for deletion. This allows you to target specific rows that need to be removed from the column. Additionally, using prepared statements can help prevent SQL injection attacks and improve the security of the deletion process. 

<?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);
}

// Define the value to be deleted
$valueToDelete = "example";

// Prepare and execute the SQL DELETE query
$stmt = $conn->prepare("DELETE FROM table_name WHERE column_name = ?");
$stmt->bind_param("s", $valueToDelete);
$stmt->execute();

// Check if deletion was successful
if ($stmt->affected_rows > 0) {
    echo "Deletion successful";
} else {
    echo "No rows deleted";
}

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