* File: background_results.php
|

||
|

|
* Change Log:
|
||
|
|
* - Feb 26, 2014 - File created
|
||
|
|
* - May 05, 2014 - Converted parsing functions to classes for threading
|
||
|
|
* - Sep 1, 2016 - Copyright updated, added CWD parameter option,
|
||
|
|
* Converted to constants, made script execution platform independent
|
||
|
|
* - Oct 24, 2016 - Added debug output and cleaned up script string generation
|
||
|
|
* - Nov 7, 2016 - If it ain't broke, don't fix it! Had to revert to a previous version because intended improvements broke it
|
||
|
|
* - Dec 7, 2016 - Fixed bug where Windows threading was not being started,
|
||
|
|
* Changed PHP constant to PHP_BIN, and make sure that script continues running until last result file is done.
|
||
|
|
* - Jan 30, 2017 - Converted script to use parse_config.ini file instead of command line parameters and set script to remove config file when all files are completely parsed
|
||
|
|
* - Feb 15, 2017 - Converted file_types constants to defined constants and removed unnecessary parameters from parse_* scripts string creation
|
||
|
|
* - Feb 21, 2017 - Fixed path issues with scripts not running
|
||
|
|
* - Oct 23, 2017 - Conditionally delete parse_config.ini only if not in DEBUG log level
|
||
|
|
* - Oct 27, 2017 - Fix to remove desktop.ini files if found
