  • This page specifies another content-type See the results here
  • This page specifies another content-type, and a download. See the results here
– Several pages that use cookies and sessions:
  • This page and this page use a cookie to set a user-defined background color. See the results here
  • Here are several pages that use session variables: You can watch them work by starting here
November 29
–Today we looked at changing data in our database.
November 23
–Today we look at aggregate functions. Look at the following:
  • This page uses PHP code to get the average price of an item in our inventory. See the results here
  • This page uses an SQL aggregate function to get the same result. See the results here
  • This page uses an SQL aggregate function with a GROUP BY clause. See the results here
November 16-18
– Today we looked at several variations on a page that selected data from a MySQL database
  • This page displayed these simple results. See the results here
  • This page displayed the same results, sorted. See the results here
  • This page displayed the same results, for those customers that live in Minnesota. See the results here
  • This page displays results from two tables. See the results here
  • This page and this page work together to show the same results, for a user-selected subset of data. See the results here
November 11
– Today we will discuss email. Here is the source of the pages we discussed:
November 9
– Today we looked at several pages that worked with this data file.
– This page displays the contents of the file in a table. See the results here
– This page displays a selection list of classes. It then links to this file to display the appropriate parts of the schedule. See this set of pages in action here
– For Part I of Assignment 7, you will need to work with this data file. It is the same as the data file used on Tuesday.
– For Part II of Assignment 7, you will need to work with this data file. It is similar to the data file used earlier in the week, but it has an extra column of data. In Part II, you will create a page that will generate a table like this.
Oct 27
–Use this page to try out regular expressions in PHP.
Web Log
–This week we worked on creating a web log. There are a few source code files we developed: To try this out, start here.
October 14
–This page demonstrates more file input. Here is the file that it reads as input (and which you'll need to work with for Assignment 6). Try it here. We'll look at a modified file in class -- here's the source, and here's it in action.
–This page demonstrates another file system function, is_readable. Try it here.
–This page has a form that contains a file input element, used to upload files to the server. It is processed by this page. The file that is uploaded is displayed by this page -- see it in action here.

–This page demonstrates some simple file input. Try it here.
–This page demonstrates more file input. Try it here.

Oct 7
–Homework files -- Here are the forms you will need for Part I and Part II of Assignment 5.

–This page demonstrates the difference between pass-by-value and pass-by-reference. Try it here.
Oct 5
–User-defined functions
–This page uses a simple user-defined function. Try it here.
–This page uses a slightly more complicated user-defined function. Try it here.
–This page uses an even more complicated user-defined function. Try it here (notice the use of a querystring in this URL).
Sep 30 – More fun with arrays and loops
–This page processes this form to get a multiplication table. Note the use of nested loops! Try it here.
–This page processes this form to divide up some text into words. Try it here.
–This page processes this form to count up the number of words of different lengths. Try it here.
–In assignment 4, you will need to write a page that will create a color table that looks something like this.
Sep 28
–Associative arrays
–This page displays the page shown here.
–This page processes this form. Try it here.
–This page processes this form (with a multiple selection list!). Try it here.
Sep 16
–Sample Problems
–Problem 1 -- This page calculates the deduction from this form.
–Problem 2 -- This page displays the temperature chart shown here.
Sep 14
–Today we will discuss arrays.
–This page uses a for loop to display a list of foods. You can see the results here.
–This page uses a foreach loop instead. You can see the results here.
–This page uses a for loop to create an order form. The order form is processed by this page. You can see the form in action here.
Sep 9
–Today we will finish our loop discussion. Here's our last example:
–We also talked about more complicated forms, such as this one. This page will show what we get from that form
Sep 7
–Today we will discuss loops. I have a few examples:
Sep 2
–Today we will discuss conditional statements. This page uses a simple conditional statement to calculate overtime. It processes this form.
Aug 31
–Here's the example from today's class. You can see the source code for this page here.
Week of Aug 23rd
–Here's an example of a simple PHP page.
–Here's an example of a simple form that can be processed with PHP. Here is the source of the PHP page that processes that form.

Resources

HTML. If you need to brush up on your HTML, check out the W3Schools

Editors. Here are some resources for text editors:

  • Interested in using vi? Read here for more information about using vi. It's a steep learning curve, but it's worth it!
  • Want to use vi on a Windows or Mac machine? Check out VIM (vi Improved). (note: this site is a PHP site)
  • Alternatively, PC users might want to try Ultra-Edit, while Mac users might want to try BBEdit

PHP on your own machine. Interested in getting PHP installed locally? Look here:

  • First off, look at the Main PHP web site. PC users -- take a look at the downloads section.
  • OS X users, you've got it easy -- PHP is already installed, you just need to activate it. Take a look at this article to see how.
