How can debugging techniques be used effectively to troubleshoot issues with DELETE queries in PHP?

To troubleshoot issues with DELETE queries in PHP, debugging techniques such as printing out the query being executed, checking for errors returned by the database, and verifying the connection to the database can be used effectively. 

// Example code snippet to debug and troubleshoot DELETE query issues in PHP

// Establish a connection to the database
$connection = mysqli_connect('localhost', 'username', 'password', 'database');

// Check if the connection is successful
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Define the DELETE query
$query = "DELETE FROM table_name WHERE condition";

// Print out the query for debugging purposes
echo $query;

// Execute the DELETE query
if (mysqli_query($connection, $query)) {
    echo "Record deleted successfully";
} else {
    echo "Error deleting record: " . mysqli_error($connection);
}

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