Verbose regular expressions in PHP?

Question

Searching on php.net I was not able to find any support for verbose regular expressions in php. Is this my fault for not knowing how to search for it, or is it php\'s fault

You can also set 'expanded' mode modifier within the regex as long as its the first char past the
delimiter.

= '/(?x)
                     # A comment
     (               # (1 start), some capture
        . 
     )               # (1 end)
  /';

And/Or, it should also be available within //x context

'/
                   # A comment
   (               # (1 start), some capture
        . 
   )               # (1 end)
/x';

Or, you can freely move in/out of x-mode within the code

'/((?x)            # (1 start), some capture
        .
       (?-x: A )   # ' A ' 
   )               # (1 end)
/'
