php - Regex to strip comments and multi-line comments and empty lines

Question

I want to parse a file and I want to use php and regex to strip:

• blank or empty lines
• single line comments
• multi line comments

basically I want to remove any line containing

/* text */ 

or multi line comments

/***
some
text
*****/

If possible, another regex to check if the line is empty (Remove blank lines)

Is that possible? can somebody post to me a regex that does just that?

Thanks a lot.

Answer 1

$text = preg_replace('!/*.*?*/!s', '', $text);
$text = preg_replace('/
s*
/', "
", $text);
