Previous Comments: ------------------------------------------------------------------------ [2004-07-09 22:57:25] danielc at analysisandsolutions dot com Curt Zirzow posted a patch for this to internals... http://news.php.net/php.internals/10968 ------------------------------------------------------------------------ [2004-07-03 06:05:05] danielc at analysisandsolutions dot com Description: ------------ In PHP 4, when using exec() multiple times with the same array in the "output" parameter, the data from subsequent exec() calls appended the new results to the existing array. This is as the manual says. When PHP 5 first came out, each call to exec() overwrote the prior array. At some point a while ago, there was discussion on the list and things were changed back to the old behavior. At some point after that, the arrays started getting overwritten again. Is this intentional? I saw no notices about it in README.PHP4-TO-PHP5-THIN-CHANGES or in the man page. Can the old behavior be reimplemented in order to preserve compatibility? I made a post about this to internals: http://marc.theaimsgroup.com/?l=php-dev&m=108874256229775&w=2 Reproduce code: --------------- <?php exec('date', $Return); exec('date', $Return); print_r($Return); ?> Expected result: ---------------- Array ( [0] => The current date is: Fri 07/02/2004 [1] => Enter the new date: (mm-dd-yy) [2] => The current date is: Fri 07/02/2004 [3] => Enter the new date: (mm-dd-yy) ) Actual result: -------------- Array ( [0] => The current date is: Fri 07/02/2004 [1] => Enter the new date: (mm-dd-yy) ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28999&edit=1
