What are the best practices for handling user thresholds in PHP scripts to ensure proper execution of specific scripts?

When handling user thresholds in PHP scripts, it's important to set appropriate limits to prevent excessive resource consumption and ensure proper execution of specific scripts. This can be achieved by implementing checks for user input values against predefined thresholds and handling them accordingly, such as displaying an error message or terminating the script if the threshold is exceeded.

// Example of handling user threshold in PHP script
$userThreshold = 1000; // Define the threshold value

$inputValue = $_POST['input_value']; // Get user input value

// Check if user input exceeds the threshold
if ($inputValue > $userThreshold) {
    die('Error: Input value exceeds threshold');
}

// Proceed with script execution if threshold is not exceeded
// Your script logic here...
