Capturing tweets

• Background request from senior project student
• I found a wrapper for the official Application
  Programming Interface (API)
• http//twitter.slawcup.com/twitter.class.phps
• http//thinkvitamin.com/code/how-to-get-started-wi
  th-the-twitter-api/
• I downloaded and then uploaded to my site
• NOTE I did not bother to study/understand the
  whole thing!
• ASSIGNMENT for you (you can work in teams) build
  your own twitter capture program.
• Probably will require you to work with incomplete
  understanding (like I did).

Client - Server

• HTML5 JavaScript program to run on the client,
  invokes
• php program to run on the server, which accesses
• twitter programs

5
Another Purchase server

• Was not necessary, but I have had to put other
  php programs on socialsoftware.purchase.edu so I
  put these there, also.
• Why?
• Server programs can change programs, files on
  server, so CTS restricts certain operations.
• reading writing uploading files

Quick overview php

• A php program (script) on server
• takes input from the html script that invoked it,
  most typically form input
• does something often invoking SQL on a database,
  and here invoking programs on twitter
• creates html to send back to browser, to be
  interpreted in normal way.

7
NOTICE

• Upload to server and test.
• NO test on your own computer
• unless.
• You can't see the source of a php program, but
  only the source of the html it produces

8
php quirks

• Variables start with
• -gt used for associative array components
• similar to dot notation in JavaScript. More when
  we do JSON
• . (dot) is used for concatenation
• Use combination of single and double quotation,
  along with \ for producing strings with quotation
  marks.
• Go into and out of php. Everything 'outside of
  php' is part of the html document sent to the
  browser.

9
My twitter example(s)

• html presents a form. Invokes php script
• php uses wrapper functions to get data
• NOT instantaneous. Need to set up to wait for
  data
• php uses data to produce (echo) html.

  in a choice or .
