You might be looking for something like the following. I haven't
tested this, so I'm sure my string parsing is off by one, or
something. Also the variable names are kind of long for clarity's
sake; you may want to shorten them.

$file_path = "/path/to/file.txt";
$contents = file_get_contents($file_path);

$start_string_position = strpos($contents, "start");
$end_string_position = strpos($contents, "end",
$start_string_position);
$extracted_string_length = $end_string_position -
$start_string_position;

$extracted_string = substr($contents, $start_string_position,
$extracted_string_length);
