Put it all together

• Write a web page on projects that creates a form
  control from your database type table and lets
  the user choose a type to see. Format the results
  in a table. Have an external CSS that makes the
  background of the table one color and the table
  itself a different color. The page should be well
  designed. Use good style.

String functions

• Assign to a variable a string describing your
  favorite web site. Print the following
  information from the string
• String length
• First occurence of the string "like"
• The string encrypted
• The string reversed
• Find the last occurence of the letter s
• Make the string all lower case
• Replace all occurances of "an" with "AN"
• Make every word start with uppercase
• Break the string into separate words

4
Creating controls from a database

• Make a form with a drop down menu containing the
  types from your lab database
• Make a form with a set of radio buttons
  containing the types from your lab database

5
Validation functions

• Write a form with a text control and check the
  input for each of the following types of data
• Zip code
• Phone number
• Email address
• Plain text
• (output like invalid zip code, valid phone,
  invalid email, valid text)

6
Header / Footer

• Write a header
• Write a footer
• Include them in 2 web pages

7
Authentication

• Write code to authenticate a user using a custom
  form
• Write code to authenticate a user using the
  browser's built-in form

8
Using echo and print

• print your name 3 times in 3 different colors.
• echo your name 3 times in 3 different font sizes.
• Show 3 different random numbers

9
Using if

• Generate a random number and tell if it is
  greater than, less than, or equal to 44
• Generate a random number and tell if it is odd or
  even. (Do it using / and do it using )

10
Using loops

• Print the numbers from 10-30 inclusive using
• while
• for
• do
• Print the letters from A to Z using any kind of
  loop
• Print the multiplication tables from 0 to 12
  using one loop inside another

11
Using arrays

• Make a numbered array of your favorite movies and
  print them out
• Make an associative array using SI course numbers
  as the key and course titles as the value
  ("SI539" - "Design of Complex Web Sites") and
  print out the key/value pairs (use foreach)

12
PHP and Forms

• Make a form with 2 different controls and a
  submit button. Write a form handler that prints
  the values of the controls when the user clicks
  submit. (use foreach)
• If you did the first one right, you can add
  several other controls to the form and get the
  correct output without changing the form handler.
• Let the user enter their name in a text field and
  choose their favorite color from a select
  control, then make a page that prints their name
  in their favorite color

PHP and Database

• Do the lab for Oct 12/14 over using a different
  form control
• Do the lab for Oct 12/14 over so the user will
  see values from the other table if they choose
  the column with the foreign key
• Do the lab for Oct 12/14 over so the user can
  choose more than 1 column to view
