The code will generate table headers, and then add one extra row for every record in the table. It will format the data as it is sent for output.

If you are familiar with PHP and HTML, which you should be by now, you will find it self-explanatory. However, the last two lines in the table will still be explained. For instance:

<a href="mailto:<? echo $email; ?>">E-mail</a>

This exemplifies one of the advantages of using PHP in including MySQL data as it can be used to output portions of your code and create fully dynamic pages.

Selecting Bits of Data

Aside from showing the entire database, PHP can also be utilized to select single or individual records, or those that match certain criteria. You can do this by using a SELECT query variation. To show the entire table, use the query

SELECT * FROM contacts

If you want to choose only those who have the first name “Jim,” you can use the following query code:

SELECT * FROM contacts WHERE first='john'

Just like other MySQL queries, the code reads like plain English, similar to how you would choose records based on a particular database field. Likewise, you have to option to select more than a single field just by adding more sections in the query:

field='value'

While we will not dwell deeper about this topic in this section of the eBook, you can use variables to provide the database criteria. If you are creating a search form, for example, you can get the last name of the person you want to search for and store the value in a variable named $searchlast. You can then execute the script that follows:
