Introduction to PHP

1. The keys for this array are automatically generated, starting at 0.  Change the code so that the keys are specified.  Change the keys to start at 5 and end at 9 instead of starting at 0 and ending at 4.
2. Now, change the array so that the value stored in the array is a random number from 1 to 5 multiplied times the key.

2) http://codepad.org/U4uV1QS5 - Using the PHP manual array function reference, modify this code chunk according to the following parameters:

1. Order the animal names alphabetically.
2. Order the animal names reverse alphabetically.
3. Print the number of animal names in the array using a function from the array function reference.
4. Order the animal names randomly.
5. Find two different ways to add a new animal name to the array.  (Hint: There are at least three ways to do this.  At least one of these ways uses a function from the array function reference).

3) http://codepad.org/ftHAnlX2 - Do the following:

1. Modify the array to include a ‘salads’ section and a ‘soups’ section.  Change the other items in the restaurant to whatever you want your restaurant to serve.
2. Print the number of items in the section after the name of the section in parentheses.
3. Add a background color to each <tr> in the table.
4. Make each section of the menu (appetizers, entrees, etc.) have a different background color.
5. Give each item a price and print it in a third table column.

4) Create an exercise for your classmates that requires the use of array variables.  The exercise can have your classmate analyze your code chunk on Codepad or provide instructions for them to build their own, or both.
