 Usage of profiler script:

  1. Setup 'php_dbg' [http://dd.cron.ru/dbg/] module on your php.ini

  2. Run DBG Listener

  3. Include this file at the end of you script

  4. To enable profiling use you script with parameters: ?DBGSESSID=1@clienthost:7869;p=1

     P.S.: see parameters bellow

  5. To disable profiling use you script with parameters: ?DBGSESSID=-1



  P.S. All DBGSESSID parameters stored in cookie. You must run in once to enable, and

       once to disable.





 *****************************************************************************

 DBGSESSID Usage:

 *****************************************************************************



 DBGSESSID=nnn[@host][:port][;{flags}]



 where



 nnn - is session ID (any positive number or zero)

  NOTE: negative values prohibit debug session to run and drops cookie



 host - is host name or IP address of the host where your run PHPED IDE.

  You may set clienthost which is a keyword, in this case debugger looks for

  proper client IP address automatically.



 flags - set of the following flags delimited with commas:

  s=skip - skip number of HTTP requests before actual session should run

  d={0|1} - start debug session

  p={0|1} - start profiler session



 For example:

  DBGSESSID=1@clienthost:7869;d=1,p=1

  DBGSESSID=1;d=1,p=0

  DBGSESSID=1:7869;d=1,p=0,s=5



On/Off:

	javascript: document.cookie = 'DBGSESSID=' + escape('1;d=1,p=0') + '; path=/'; document.execCommand('refresh');

	javascript: document.cookie = 'DBGSESSID=' + escape('1;d=0,p=0') + '; path=/'; document.execCommand('refresh');



	javascript:location.href=location.protocol+'//'+location.hostname+location.pathname+'?DBGSESSID=1;d=1,p=0'

	javascript:location.href=location.protocol+'//'+location.hostname+location.pathname+'?DBGSESSID=-1

Summary ✨

The PHP code generates a graphical representation of execution time for a set of files, displaying the total execution time, individual file times, and line-by-line execution times with hits counts. It highlights slow lines in different colors and displays the source code of each line in a readable format. The output is a table-based visualization of the execution data.
