What are the common pitfalls when working with $_POST in PHP?

Common pitfalls when working with $_POST include:

• Forgetting to set form method: Ensure the form uses method="post" to send data via $_POST.
• Not validating input: Always validate and sanitize inputs to prevent security issues.
• Incorrectly handling data: Check that data is handled correctly and errors are managed appropriately.
• Ignoring error handling: Implement robust error handling to catch issues with data submission and processing.
