price input value 100,000.00 convert to decimal?

[searain]

instead of using the functions provided in
http://ca.php.net/manual/en/function.floatval.php

If I only want to get off the "," for the US/Canadian/International number format. such as 100,000.00, could I just use the str_replace to strip off the ","?

Anything I will miss? or any better functions I can use?

Thanks!

Not really. Although you could use ereg_replace and use a ereg phrase to catch any non numeric (or .) characters. This will then handle european numbers which are of the form 100 000,00.

Except sometimes they're of the form
100.000,00

and sometimes
100,000.00

and sometimes

100.000,-

It depends pretty much on where you are and what the context is.

Just eregi'ing out the nonalpha's could leave you with a tricky problem though.

If, after the eregi, I'm left with 1000000, how do I know whether there was a decimal indicator somewhere along the way?

It takes a bit of thinking to sort out a truly generic solution to this. And you're still left with assumptions. Does 1,000 represent "one point zero zero zero" or "one thousand" it could be either.

But it can be done.

This is all getting more complicated that the original question, to which the answer is Yes, you can use str_replace to replace commas with empty strings - ie remove them.

OK so we are not just talking about someone entering one regular form but the site needs another. You want to mkae sure they enter a valid number in any form. This is hard and will involve quite a lot of code. Far better to force users to user a number in the form you want. The whole world recognises ####.## form. So simply bounce the form if it not in this form.
