Req #52073 [NEW]: RFE: a few more options to exec()

From: Operating system: PHP version: Irrelevant Package: Program Execution Bug Type: Feature/Change Request Bug description:RFE: a few more options to exec() Description: ------------ Exec() is missing a few key features: 1. The ability to return STDERR separately from STDOUT. At the moment, we can get STDOUT back in $output, but STDERR is either logged (for php-cgi) or sent to the main script STDERR (for php-cli). The user has the choice to append "2>&1", but it would be really helpful to have stderr and stdout both returned in separate arrays. 2. The ability to choose the shell. At the moment, exec() uses apache's shell, which is usually /bin/sh (either as bash or ash depending on distro). If bash-isms are required, we can work around this with "bash -c '...... '", but it would be a nice feature. 3. If a process is forked, then we'd like to get the PID, $!. Currently this can only be achieved thus: exec ("foo & echo $!", $output) but we must sacrifice stdout for the purpose. 4. Optionally, some way to do execv("arg1", "arg2", "arg3"....) Test script: --------------- I'd suggest having a function: exec( string $command [, array &$stdout [,int &$retval [,array &$stderr [,int &$pid [,int options = BASH|SH|CSH ] ] ] ] ] ) -- Edit bug report at http://bugs.php.net/bug.php?id=52073&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52073&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52073&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52073&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52073&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52073&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52073&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52073&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52073&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52073&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52073&r=support Expected behavior: http://bugs.php.net/fix.php?id=52073&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52073&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52073&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52073&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52073&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52073&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52073&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52073&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52073&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52073&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52073&r=mysqlcfg
