asumming replacing the call with ; is valid everywhere it's going to a heck of
a lot faster than calling _any_ function.

1. use a debugger rather than writing lots of code that logs tons of 'cr*p'?
2. always use braces? so that you can do:
if(conditions ....) {
# $this->debug('something...');
}
3. may put special comment markers in your code that allow you
to filter the files when you 'publish' them into a production env.
/*START_DEBUG_BLOCK*/
if(conditions ....)
$this->debug('something...');
/*END_DEBUG_BLOCK*/
i.e strip the blocks completely:
$newFile = preg_replace( '#/\*START_DEBUG_BLOCK\*/.*/\*END_DEBUG_BLOCK\*/#',
'',
file_get_contents( $yourPhpFile ) );
