Query: “What are the most common pain points with PHP for developers in 2025?”4/8/2026

Use of Semicolon: It's funny how one little character can create havoc in a program, without even being reported to the PHP error logs... Sometimes we use '=' in place of comparison '=='. This mistake can change the value and logic of your code.
