Are there any changes in PHP documentation regarding commenting out code that developers should be aware of?

When commenting out code in PHP, developers should be aware that using double forward slashes (//) will only comment out that specific line of code, while using /* */ will comment out multiple lines of code. It is important to ensure that commented-out code is kept up to date and removed when no longer needed to avoid confusion and clutter in the codebase. 

// Single line comment
// $variable = "This line of code is commented out";

/*
Multi-line comment
$variable = "This block of code is commented out";
$variable2 = "This block of code is also commented out";
*/
