Load common-settings.php and get 3 x querystring params, exploding first 2 into arrays $result is OK to start with, but if we have a file that's not available, set it to error If we don't have an error, the seen sizes aren't null and the seen and actual sizes don't match, we need to get bug lines Set $result to bugs and some vars to begin with fseek, ftell and while loop to get chunks of content using pointer movement methods. We also reduce $chars and $lines here to escape the while loop as required $output has line endings converted and trimmed, before exploding on new lines and only getting last few lines, stitched back together with imploder The bug report is written, $tmpLoc established and all data put into the $status array to feed back in the XHR response
