如何为proc_open设置正确的PATH

Question

I have a piece of code as follows:

$process = proc_open(sprintf('node "%s"', $tmpfile), $desc, $pipes);

Which produces

sh: node: command not found

I tried to set $PATH in httpd.conf with SetEnv, then echo it using getenv('PATH'). The output actually contains the path to node.

I was able to pass the variable to proc_open, but I'd like to avoid that because it's someone else's code.

Is there a way for me to give it the correct path?

I am running XAMPP 1.8.2 for Mac OS X.

After the $pipes you can assign the CWD. You should pass it here. In terms of setting the cwd with the php.ini file, I don't think this is possible.

You should be able to do the following:

$process = proc_open(sprintf('node "%s"', $tmpfile), $desc, $pipes, __DIR__);

Providing the "node" executable is in the same directory. Alternatively you could move "node" to

echo getcwd();

Although this is a bit messy usually.

Edit: You should also be able to get away with using an alias or symlink to the cwd
