stripping out all characters from a string, leaving numbers

I have something produced by an API that looks like: 34 Canadian Dollars. I’m trying to get rid of the alphabetical characters and keep only the numeric characters. How can I do that?

Answer 1

Given the fact that you’re working with currencies and that the number may contain a comma or decimal point, you should use this instead:

preg_match('/([0-9\.,]+)/', $input, $matches);

// Output the amount.
echo $matches[1];
