to put a literal dollar sign in a regex it has to be escaped \$

to put a backslash in a double quoted string you have to escape it \\$

in order to put a literal dollar sign in a double quoted string you have to escape it \\\$

or you can use sinlgle quotes - where you only have to escape the dollar sign once to mark it a a literal dollar sign and not an end string/line placeholder

preg_match('/\$example/' , $matchme))

12-Mar-2000 03:23 If you want to use some of PHP's special characters in your expression,
such as $, you must escape it twice. For example:
$matchme = "\$example"; if (preg_match("/\$example/", $matchme)) {
will not be matched because PHP interprets the \$ and passes it as $.
Instead, you must do this:
if (preg_match("/\\\$example/", $matchme)) {

Don't forget to check the manual.

Hokay, that works, but what's with the triple backslashes?

preg_match ("/^.*_\%split\%_$(\d*\.\d*)/", $data, $match);

Should be

preg_match ("/^.*_\%split\%_\\\$(\d*\.\d*)/", $data, $match);
