Bug #74074 [NEW]: "||" is not useful on windows's program execution function.

From: phith0n dot ph2f at gmail dot com Operating system: Windows PHP version: 5.6.30 Package: Program Execution Bug Type: Bug Bug description:"||" is not useful on windows's program execution function. Description: ------------ I use iis7.0 && php5.6.30(I also test in apache+php, the result is same) to run following php code ``` <?php $cmd = "error_command || whoami"; exec($cmd, $output, $return_val); var_dump($output); var_dump($return_val); ?> ``` If the first command is wrong, then the second command wouldn't be executed, the output is ``` array(0) { } int(1) ``` But I run the code on windows+built-in webserver, the output is ``` array(1) { [0]=> string(12) "71ec\phithon" } int(0) ``` Cli's result: ``` F:\PHPStudy\WWW>F:\soft\php-5.6.30-Win32-VC11-x86\php.exe test\a.php 'error_command' 不是内部或外部命令，也不是可运行的程序 或批处理文件。 array(1) { [0]=> string(12) "71ec\phithon" } int(0) ``` So why php has 2 different results? Test script: --------------- <?php $cmd = "error_command || whoami"; exec($cmd, $output, $return_val); var_dump($output); var_dump($return_val); ?> Expected result: ---------------- array(1) { [0]=> string(12) "71ec\phithon" } int(0) Actual result: -------------- array(0) { } int(1) -- Edit bug report at https://bugs.php.net/bug.php?id=74074&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74074&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74074&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74074&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74074&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74074&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74074&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74074&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74074&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74074&r=support Expected behavior: https://bugs.php.net/fix.php?id=74074&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74074&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74074&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74074&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74074&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74074&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74074&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74074&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74074&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74074&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74074&r=mysqlcfg
