Matching regular expression with Date/Numbers

Question

I need some help creating regular expressions to pick information out of a file. I am using php preg_match to do it and am trying to get information that looks like the following:

ex.

19-Aug-2013 //The date will always be in the format.

and a number like this

303.00

The file I am trying to get this information from is the body of a mime type email.

I only need these two types of specific information.

Answer 1

Try this as a whole:

preg_match_all('/(\\d{2}-\\w{3}-\\d{4}|\\d+\\.\\d{1,2})/', $file, $matches);

\\d{2}-\\w{3}-\\d{4} : Get the date

\\d+\\.\\d{1,2} : Get the float

By using preg_match_all you return all found matches in all the haystack. preg_match only matches the first occurance.

Answer 2

For the date you can use:

[0-9]{2}-[a-z]{3}-[0-9]{4}

For the number:

[0-9]+\.[0-9]{2}

With no specific input is hard to come up with a better regex at the moment...
