How can PHP variables be effectively used to track the status of database entries in error handling scenarios?

When handling errors in database operations in PHP, variables can be used to track the status of database entries. By setting a variable to indicate success or failure after each database operation, we can easily check and handle errors in the code. This allows for better error handling and provides a clear indication of the status of database entries. 

// Example of using PHP variables to track the status of database entries in error handling scenarios

// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database');

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

// Variable to track the status of database entry
$status = '';

// Insert into database
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";

if ($connection->query($sql) === TRUE) {
    $status = 'Entry successfully added';
} else {
    $status = 'Error adding entry: ' . $connection->error;
}

// Close connection
$connection->close();

// Output status
echo $status;
