What general advice is given in the forum thread for developing PHP scripts to avoid errors?

The general advice given in the forum thread for developing PHP scripts to avoid errors is to always sanitize user input to prevent SQL injection attacks and validate input data to ensure it meets the expected format. Additionally, it is recommended to use error handling techniques such as try-catch blocks to gracefully handle exceptions and avoid displaying sensitive information to users. 

// Example of sanitizing user input to prevent SQL injection
$userInput = $_POST['input'];
$cleanInput = mysqli_real_escape_string($connection, $userInput);

// Example of validating input data
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // Email is valid
} else {
    // Email is not valid
}

// Example of using try-catch block for error handling
try {
    // Code that may throw an exception
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
