Question

I have a string like “You can win tonight $200,000. Sign up now!”

Where the prize is changing from string to string, so I have to do it somehow using php regex or somthing like that.

How to get just this value from this string using php?

Is there a simple regex function?

Thanks in advance.

You’re looking for preg_match, I think:

 preg_match("/\$[\d\,]+/", "You can win tonight $200,000. Sign up now!", $matches);
 # $matches[0] will be "$200.000"

Breaking it down:
The regular expression look for a dollar sign (which has special meaning in regular expressions, so we escape it with backslash, so it’s taken as literal dollar sign), followed by 1 or more digits (0-9) and commas.

Note that if preg_match itself returns false, it’s because the string didn’t match the regexp, and in that case, there will be no $match[0] to read
