Question

I have a form where users can enter the amount they spend on their phone bill and then I tell them how much they could save if they switched to vonage, skype etc.

I pass the value ‘$monthlybill’ in the url and then do some math to it. The problem is that if the user writes ‘$5’ instead of ‘5’ in the form, it breaks and is not recognized as a number. How do i strip out the dollar sign from a value?

Answer 1

$monthlybill = str_replace("$", "", $monthlybill); 

You might also want to look at the money_format function. if you are working with cash amounts.
