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 ]
] ] ] ]
)
