I'm currently working on a PHP project and I've encountered a small hurdle. I need to run a shell command within my PHP code and capture the output into a variable. However, I'm not quite sure how to achieve this.
To provide you with some context, I'm building a website where users can upload a file, and then I need to run a shell command on that file to process it further. I want to capture the output of this shell command into a PHP variable, so that I can handle it within my code.
I've tried using the `exec()` function in PHP to run the shell command, but I'm not sure how to retrieve the output. Can someone please guide me on how to accomplish this? I'd really appreciate any help or suggestions.
Thank you in advance for your assistance!
