Passing data to Python from a jQuery/HTML or a PHP file

I want to create an HTML/jQuery or PHP file that should get its input from a constantly running Python script.

• The file should be dynamically updated using inputs from a constantly running Python script.
• I would like to refrain from using any complex web frameworks for this. I already have Apache2 installed, and would like to use that.
• The simplest way would be reading/writing to/from files. But I would refrain from that as much as I could for our security concerns.

Is there any way to achieve this communication by using what's available. I would really appreciate any guidance in this regard.
