#25727 [Fbk->Opn]: popen returns wrong exitcode

ID: 25727 User updated by: eru@php.net Reported By: eru@php.net -Status: Feedback +Status: Open Bug Type: Filesystem function related Operating System: i386 Linux PHP Version: 4CVS-2003-10-02 (stable) New Comment: What has the fread/fgets to do with the problem? I'm talking about the exitcode here. The fread-line is just a demonstration, that the command is carried out correctly. Previous Comments: ------------------------------------------------------------------------ [2003-10-02 08:20:43] wez@php.net Try using fgets() ------------------------------------------------------------------------ [2003-10-02 08:00:43] eru@php.net 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 this bug report at http://bugs.php.net/?id=25727&edit=1
