Thanks to the suggestions, I use number_format($my_number, 2) to format the
number in an edit field. Now I need to reenter it into MySQL. How should I use
preg_replace to remove the commas?
This removes the commas *and* the decimal point:
preg_replace('/\D/', '', $str)
In reviewing patterns, I cannot find the purpose of the "/" character in the above.
Many thanks....

the / in above is the start and end token. for every preg_* function,
this is used.
You could replace it by any other character as long as it is the same
for start and end.
so above could also be
preg_replace('%\D%','',$str);
I use % nearly allways, because i like it, and it isn't used a lot. /
might be used in paths and can get confusing when \ also used.
