using php preg_match to find a single number

Question

I am trying to find a single ID from a HTML page i am pulling with cURL. The id is in a url query string that finishes like so:

start_working&locID=12008'

Since that's the only place where that piece of text appears in the html i am guessing thats the pattern we are looking for.

All i need is that locID number.

Like:

preg_match("start_working&locID=".$what_i_want."'")

I am really bad with regex and preg match

$match = array;
preg_match('/start_working&locID=([0-9]+)\'/', $yourHtmlToParse, $match);

Then you can use $match[1] for your result.

(\d+) is the pattern to get you numbers. You also need / delimiters / in your regex.

You might also want to investigate parse_str() though, after extracting the full URL.

parse_str() would not work as i am trying to get this ID froma full page of html

Mario's sugestion is not incorrect, and it WILL work if you fetch full url!
