I have a PHP script, say a.php, which is called from JS using Ajax (this is a POST request and some data is passed to the script).
I have another PHP script, say b.php, from which I would like to call a.php and pass it some data. I expect a.php to do the job just like if it was called from JS.
I don't want to do include('a.php'); because of possible collision between variable names.
How could I do this ?
Why aren't you just putting these together as functions, using an include, and calling them like you would in C++ or something? Global is bad.
One solution (if imperfect) is to use file_get_contents() with a URL.
So, something like:
$data = file_get_contents('http://domain.com/a.php?this=that&that=this');
$json = json_decode($data);
You can call it over HTTP with curl or file_get_contents. But I think you should consider a redesign. Whether you code procedurally or with OOP, you should be able to have a multi-file program without collisions.
If you are using PHP 5.3 you could use Namespaces to avoid your variable name collision issue.
Another suggestions would be to refactor your code so that you could include the file and then call a function to execute it. All variable inside a function call only have a scope of the function.
One way would be to intiate a server request from b.php with the URL for a.php that is normally used by the client.
