That means, before the HTML or other output is sent to Apache to be served to the client, PHP has parsed, interpreted, processed, and returned all of the code, and then terminated the PHP process. As to why code execution appears to take longer on slower connections, my guess would be that it's a matter of coincidence. You could try doing something like this, if you don't already have something similar in place: <? // Add to the VERY top of the file being executed, before includes, et cetera. function microtime_float() { // Don't put in include file; that file will have to parse list($usec, $sec) = explode(" ", microtime()); return ((float)$usec + (float)$sec); } $_SCRIPT['exec_sess'] = time(); $_SCRIPT['client_ip'] = $_SERVER['REMOTE_ADDR']; $_SCRIPT['time_start'] = microtime_float(); // Continue with your code.... /* YOUR CODE HERE */ // Now, at the very bottom of the script.... $_SCRIPT['time_stop'] = microtime_float(); $_SCRIPT['time_total'] = round(($_SCRIPT['time_stop'] - $_SCRIPT['time_start']),4); $write_contents = <<<EOL == SESSION $_SCRIPT['exec_sess'] for $_SCRIPT['client_ip'] == Start recording: $_SCRIPT['time_start']; Stop recording: $_SCRIPT['time_stop']; Total execution time: $_SCRIPT['time_total']; EOL; file_put_contents('./php_exec_time_log',$write_contents,FILE_APPEND); ?> -- Daniel P.
