Let's say I have two programs: 'foo' and 'bar'. 'foo' always returns an
exit code of 10. 'bar' always exits normally (i.e. returns 0).
If I do: `foo | bar` in my shell, the shell will return 10.
If I do: exec('foo | bar', $ignoreMe, $returnCode) in PHP, $returnCode
will contain 0.
Is there a way to detect a pipe's first process' exit code in PHP ?
Background info and an idea: my shell is tcsh. In the above example,
tcsh and csh report the 10 exit code, whereas bash and sh would return
0. Thus, the above question *might* be equivalent to: "Is there a way to
specify in which shell 'exec' should execute commands?"
Thanks in advance...

This may be obvious, but....
1) Implement the '|' in your own PHP code, and call proc_open twice.
(or use a Unix socket inbetween but still invoke the programs
independently from your own code)
2) exec("sh 'foo | bar'");
beyond that....ask on tcsh group?

Hi all,
I am just wondering if something is wrong with my program. What it
bascially does is to output a fibonacci sequence base on the
command-line output. If I give a 5, it will generate the first 5
fibonacci number. The problem is, I thought the parent process will
always go first, and so here I should get "0, 1, 1, 2, 3" But I ran the
program, it will give me "1, 2, 3, 0, 1", which is, the child process
ran first. Is there any way...

Hi all,
I am porting a win32 c++ program on Linux which first reads a list of
processes and their paths from a file.Then this program should launch
all of thesese processes.
I tried to achieve this using fork() and execv() API calls. but
execv() method call is synchronous
and does not return untill user closes the child application or a
launch program error occurs.

I have a class that builds a DataTable and then, when the process is
exiting, tries to write that DataTable to SQL Server 2000 via the
SqlBulkCopy class. I know the process is exiting because I'm catching

The problem is that calling WriteToServer as seen below will

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

For most users, this new feature is actually very convenient. If you want to control the update process,...
