Execute PhantomJs script from PHP on Ubuntu 16.04

Question

I am trying to run PhantomJS from a PHP script using exec('/path/to/phantomjs/phantonjs --version'); This line works fine from the CLI but does not work at all from my PHP script.

I have searched around for a fix and found this Q/A and read something about permissions that can be the problem. I have try all these fixes and still, PhantomJS does not launch.

I'm desperate at this point, can someone help me out? Thanks.

Are you expecting that to output something? You need to echo the returned value. — pguardiario

I have echoed it and even tried adding an output array as second parameter for exec but the command simply does not run. :( — Eddy Ntambwe

Can you create a minimum version of your script that doesn't work, and post that? Have you been able to get exec to work using the interactive interpreter using php -a? — daphtdazz

I have PhantomJS in /usr/local/bin. The binary is executable and I have both permissions and ownership. I use a script as simple as $cmd = '/usr/local/bin/phantomjs --version'; This obviously works flawlessly from the CLI but when called from PHP with: $response = exec($cmd, $out, $status) ; The status returns true meaning the command was not executed and both $response and $out are empty. Not null but respectively an empty string and an array of strings with one empty string element. — Eddy Ntambwe

Your path looks wrong in the exec command, it uses phantonjs where I'd expect it to be phantomjs. Might that be the problem?

I solved it. PhantomJS required som libraries that were not found in my Xampp packages and was just failing silently and updating the logs. So I just install the standalone PHP and Apache services and everything worked fine.
