3.

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).

6. 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 $ -> 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.
