You can use the regex likewise to perl. Try it here:
http://www.php.comzept.de/rexpr/index.php4
Instead of the /g option use the function preg_grep() in PHP.
Read the file in an array with file(), then grep through
the array with the regex to get the right lines. Want a
string? implode() without delimiter.
