How can PHP developers effectively troubleshoot and debug issues related to data saving functionality within PHP scripts?

To troubleshoot and debug issues related to data saving functionality within PHP scripts, PHP developers can start by checking for any errors in the code, ensuring that the database connection is established correctly, and verifying that the data being saved is formatted correctly. They can also use tools like var_dump() or print_r() to inspect variables and data at different stages of the script. 

// Example code snippet to troubleshoot data saving functionality in PHP scripts

// Establish database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Sample data to save
$data = "Sample data";

// Format data if needed
$formatted_data = mysqli_real_escape_string($conn, $data);

// Save data to database
$sql = "INSERT INTO table_name (column_name) VALUES ('$formatted_data')";

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

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