What are the potential pitfalls of using increment/decrement operators like ++$i and $i++ in PHP?

Using increment/decrement operators like ++$i and $i++ can lead to confusion and unexpected behavior, especially when used in complex expressions or nested loops. To avoid potential pitfalls, it is recommended to use the operators in a clear and straightforward manner or to separate the increment/decrement operation from other operations in the code. 

// Example of using increment operator in a clear and straightforward manner
$i = 0;
$i++;
echo $i; // Output: 1
