Re: removing double backslashes and leaving singles

Don't forget you need to escape the backslashes both for PHP and the regular expression engine. So, if you want to match \\, you need \\\\ to escape for php, then escape them both again for regex \\\\\\\\. \\\\ matches just one real backslash :) adamw ----- Original Message ----- From: "Dennis Gearon" <gearond@oit.edu> To: <php-general@lists.php.net> Sent: Tuesday, May 22, 2001 5:10 PM Subject: [PHP] removing double backslashes and leaving singles > I've tried this and it doesn't work, any ideas? > > $illegal_chars="[^a-zA-Z0-9._\\:]|\\\\"; > $dir="c:\\t.e.s.t.\\\\7."; > $dir_name = ereg_replace($illegal_chars, "", $dir_name); > > it removes the single double slash after :, as well. > > this is on version 4.0.3pl1 > > would some people please test this on their boxes/versions? > > I tried preg_replace(), and it did the same thing.
