What are some examples of side effects that may be caused by using certain operators in PHP?

Using certain operators in PHP may cause side effects such as unexpected behavior or errors in your code. To avoid these issues, it's important to carefully review the documentation for each operator and understand how it works before using it in your code. 

// Example of using the ternary operator without proper handling
$condition = true;
$result = $condition ? 'true' : 'false';
echo $result; // Output: true
