(Preamble: This seems like such a typical thing to want to do that I was surprised I didn't immediately find examples and tutorials about it.So I thought it would be valuable to have as a StackOverflow question.Pointers to related examples and tutorials will certainly be welcome answers.)To make this concrete, the goal is a webservice that accepts data in JSON format via a POST request.The data is simply an array of single-digit integers, e.g., \[code\][3, 2, 1]\[/code\].On the server are images named 0.png, 1.png, 2.png, etc.The webservice takes the images corresponding to those specified in the JSON array and composes them into a montage, using the standard ImageMagick command line tool.For example,\[code\]montage 3.png 2.png 1.png 321.png\[/code\]creates a new single image, 321.png, composed of 3.png, 2.png, and 1.png, all in a row.The accepted answer will be in the form of complete PHP code that implements the above.(I'll write it if no one beats me to it.)
