Grabbing a string from a continously changing text file in PHP

Well, I have a text file that constantly changes. The part of the text file is this important line:

e=username

The username part of it changes constantly, but I need to capture the username part of e=username string and put it into a variable every time it changes. Problem is I don't know how to. The file name is replace.txt

filemtime() returns the time the file was last modified. Poll this timestamp every so often and read the file to check for a new e=username entry if the timestamp is later than the previous time you checked.

The timestamp is given in seconds, so there's no point checking it more than once a second. If you need more frequent updates, you'll have to read the file continuously as the last modified time is stored with second accuracy.

To extract username from e=username, you can use preg_match():

if (preg_match("/^e=(.+)$/", "e=username", $matches))
    print $matches[1];
