wanna execute a bin proggy and get result

[tom]

Problem:
In PHP, need to execute a program in (freebsd terms) /usr/local/bin
in meta-terms:
int i;
i = [execute command](arguments);

There seems to be quite a few execution methods in PHP
(sorry in advance for being thick), and, er, I was
wondering if someone could give me a quick pointer
to appropriate ones I should study to:

1. execute a command and wait till it finishes
2. enable a bunch of arguments to be sent to it
3. receive an integer from the completion of that command
{i.e. if the command is in C++,
which it will be, then it returns from and exit(interger) }.
Maybe, as a bonus,
4. timeout if the command does not return

Its a lot to ask, but from what I see so far in PHP
(and I am becoming a fan) then I reckon it can be done.

Many thanks, tom

$res = `/usr/local/bin/cmd_to_execute param1 param2`;

$res will be a string of stdout

It's important to note that those are *backticks*. Single quotes would
dump the line as a string into $res. Also, if safe mode is enabled,
then the backtick operator won't work. It'd probably be better to use
exec().

*nix: $res = exec("/usr/local/bin/cmd_to_execute param1");
- or -
Windows: $res = exec("c:\somewh ere_in_the_syst em_path\foo.exe param1");

Good notes 'bout the backtick (and a couple of samples):

http://www.php.net/manual/en/language.operators.execution.php

exec():

http://www.php.net/manual/en/function.exec.php

The documentation at php.net just rocks... if you have a good idea of
what you're looking for is called. =)

Warm regards,

In regards to (4), there's no good way to do it in PHP.

you could possibly try wrapping the call in another php script that your
main one calls, and do a set time put to that script.

just a thought, not tested, so, it a theory ;)
