I am not sure I am completely understanding your situation, but would
something like this work:
1) Read the file into a variable, like with file_get_contents()
2) Find the numeric position of the first string, maybe with strpos()
3) Find the numeric position of the last string, again, with strpos()
4) use substr() to grab the string in between
substr (filestring, firstpos, length ) where length=lastpos-firstpos

5) Write string returned in #4 to a file
Put the whole thing in a loop for each file.
