If you like using block comments then you might like this little time saver to toggle block comments much more lazily. The lazy block comment syntax uses /* and //*/ instead of the conventional /* and */. I have not seen this syntax anywhere else but I’ve been using it for years. Here is how it looks in code:

$id = get_user_id();
$age = get_user_age($id);

/*
debug_output($id);
debug_output($age);
var_dump(get_user_data($id));
//*/

$data = get_user_data($id);

To uncomment the entire block just add an extra / to the opening comment, essentially commenting out the opening block comment by converting it into an inline comment. This makes it very easy to toggle the entire comment block:

$id = get_user_id();
$age = get_user_age($id);

//*
debug_output($id);
debug_output($age);
var_dump(get_user_data($id));
//*/

$data = get_user_data($id);

The whole block is now uncommented because the starting and ending block comments are themselves commented out using the inline comment syntax //.

From now on when you consider block comments, remember the lazy syntax: /* and //*/ to comment. //* and //*/ to uncomment.
