What are the more mature frameworks for data collection and analysis in PHP or Python?

I now need to automate data collection on the list of articles in a Web site and the actual content in the list, which can get the ID of each article, And each article through a unified interface (parameter with that article ID to get to the corresponding JSON) there is a part of the data need to collect and then analyze data.

Is there any more mature frame or wheel that can meet my needs? (Multi-threading, and can run at 7x24 hours, because the number of acquisitions is huge)

In addition to ask, how to store the collected content (million to tens of millions), the data there are some digital data, the need for statistical analysis, with MySQL can it? Or is there any other more mature and simple wheels that can be used?
