What are the potential pitfalls of using T_ENCAPSED_AND_WHITESPACE in PHP code?

Using T_ENCAPSED_AND_WHITESPACE in PHP code can lead to syntax errors or unexpected behavior, especially when dealing with complex string concatenation. To avoid these pitfalls, it's recommended to use double quotes for string interpolation instead. This ensures better readability and less error-prone code.
