#25727 [NEW]: popen returns wrong exitcode

From: eru@php.net Operating system: i386 Linux PHP version: 4CVS-2003-10-02 (stable) PHP Bug Type: Filesystem function related Bug description: popen returns wrong exitcode Description: ------------ Apparently this has something to do with the environment-variables in the shell, popen uses to execute the command. If I replace "echo FOO" with "export" I get the whole line of variables and then it fails, whereas the successful execution only has one, BASH=/bin/sh. I use php -n so no php.ini is used. Reproduce code: --------------- <?php $pp = popen("echo FOO", "r"); echo fread($pp, 4096); var_dump(pclose($pp)); ?> Expected result: ---------------- FOO int(0) Actual result: -------------- FOO int(-1) -- Edit bug report at http://bugs.php.net/?id=25727&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25727&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25727&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25727&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25727&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25727&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25727&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25727&r=support Expected behavior: http://bugs.php.net/fix.php?id=25727&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25727&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25727&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25727&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25727&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25727&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25727&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25727&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25727&r=float
