I'm building a web service, and I can't seem to figure this out. I've Googled everywhere, but nothing seems to fit as I need it. The user enters details into the website, and then a PSD file is edited via ExtendScript with the details they've entered. The file is saved, and available to download to the user. I have the script complete, the PSD ready and the PHP set up as I want it, but I can't seem to figure out how I can launch the script automatically from PHP. I've tried a few things and nothing seems to work. Any ideas would be great, I think I've been staring at it for too long and am jsut confusing myself now.
