What steps can be taken to debug and resolve issues like missing database entries or incomplete data insertion in PHP scripts?

Issue: Missing database entries or incomplete data insertion in PHP scripts can be debugged and resolved by checking the database connection, ensuring proper SQL queries are being executed, and validating input data before insertion. PHP Code Snippet: 

// Check database connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Ensure proper SQL query execution
$sql = "INSERT INTO table_name (column1, column2) VALUES ('$value1', '$value2')";
if (mysqli_query($conn, $sql)) {
    echo "Data inserted successfully";
} else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

// Validate input data before insertion
$value1 = mysqli_real_escape_string($conn, $_POST['value1']);
$value2 = mysqli_real_escape_string($conn, $_POST['value2']);
