Thanks for your contribution! I don't use regex much, and so each time I needed to use it, I had to go back and nearly relearn it. This site is great!

Title: Actual working currency regex

I have seen several published regex supposedly for handling US currency but, all were flawed, in that, they did not work, some allowing multiple decimals into the number or
leading zeroes where none should be.
I am not saying mine is not flawed and this is no challenge but, I believe it is error free. However, I do make liberal use of parenthesis to clearly delineate components.
I wanted a regex to handle a U.S. currency amount of no more than 999 million with optional leading $, commas, trailing decimal places and leading zero for pennies only value.
This will do that.
^ (\$?) ( ( ([1-9]) ([0-9]{0,2}) ((,?[0-9]{3}){0,2}) ) | ([0-9]?) ) ((\.[0-9]{2})?) $
^ beginning of line
(\$?) optional dollar sign - escaped for use as a literal
( beginning of OR condition
(
([1-9]) first digit must be greater than 0
([0-9]{0,2} up to two more digits in first tri-number set
((,?[0-9]{3}){0,2}) comma is optional but, up to two more tri-number sets
)
| OR condition
([0-9]?) optional single leading 0 before the decimal
) end of OR condition
((\.[0-9]{2})?) optional decimal point to two positions
$ end of line
Here is a sample preg-match use of the regex. However, note the triple escaped leading $ sign; preg-match rquired I do this but, I do not know why. Maybe someone out there can explain.
The single escape is the regex standard.
if ( ! preg_match( "/^(\\\$?)((([1-9])([0-9]{0,2})((,?[0-9]{3}){0,2}))|([0-9]?))((\.[0-9]{2})?)$/", $_POST["request"] ) )
{
$status = false;
}

Greetings, nice regex. Could you modify it a bit?
From
^\$(\d{1,3}(\,\d{3})*|(\d+))(\.\d{2})?$
To
^\$(\d{1,3}(\,\d{3})*|(\d+))(\.\d{1,})?$
Matches to the tenths digit only, eg '117.8'
Kind regards,
jab

^\$((\d{1,3}(\,\d{3})*|(\d+)))?(\.\d{2})$
will require cents but make dollars optional
^\$(?=\d|\.)((\d{1,3}(\,\d{3})*|(\d+)))?(\.\d{2})?$
will make dollars or cents optional but not both. However it requires lookahead support.

Parsing a name with a regex perfectly probably is not possible. A regex like http://www.regexlib.com/REDetails.aspx?regexp_id=486, which is geared for .Net, should do a fair job for most names in the format it's expecting but it won't be perfect.

My only suggestion would be to make the Dollar Sign optional (update below) if the value is being inputted by a user.
^(\$)?(\d{1,3}(\,\d{3})*|(\d+))(\.\d{2})?$

Removing the \$ from the begining of this expression will accomplish that.
