From: danielc at analysisandsolutions dot com Operating system: Windows 2000 PHP version: 5CVS-2004-07-03 (dev) PHP Bug Type: Unknown/Other Function Bug description: exec()'s output array overwritten
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 bug report at http://bugs.php.net/?id=28999&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28999&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28999&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28999&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28999&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28999&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28999&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28999&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28999&r=support Expected behavior: http://bugs.php.net/fix.php?id=28999&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28999&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28999&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28999&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28999&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28999&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28999&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28999&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28999&r=float
