Anti-QSL Injection. I'm sure it could be better, so any improvements are welcome.

This is a mysql php pager class that I found online somewhere and modified.

A database API written in Perl for a MySQL.

You will need to edit the settings for your server.

List the databases on a MySQL serve

If you've ever wanted to build an application that can both find the distance between two zip codes, and find zip codes within a specific radius of another zip code, then this is the snippet for you.

I've tried to build this before using PHP4 and MySQL 4 and have found it to be painfully slow for a one-user connection over a Local Area Network (LAN). So, before you continue reading, I must make it abundantly clear that this method requires PHP 5 and MySQL 5.

This is because in PHP5, we will need the MySQL-Improved interfaces, and in MySQL 5, we will need functions and procedures.

Using functions and procedures in MySQL puts the weight of the calculations on MySQL, where they will run hundreds of times faster than if PHP were to attempt to do the work. In addition, using functions and procedures is still hundreds of times faster than carefully crafted SQL statements (one benchmark took over 10 seconds using a WHERE clause, while the function + procedure method took around .12 seconds--note the dot).

Since I am not a mathematician by trade, I found the necessary calculations using Google.

For the "Great Circle Distance" formula, I used Meridian Word Data's website. For the radius finder, I used another that unfortunately I do not have off the top of my head right now. I will look for it again and repost it for proper accreditation.

For the zip code database, I am using the free zip code database from CFDynamics.

Below, you will find the database and table schema, the functions and procedures, and also a demo PHP script to see all of this put into action. As a courtesy, you may download a dump of this database from my website. It's uncompressed size is 3.4M, and it's compressed size is 537K. The checksum is available here.

Please leave me comments, suggestions, questions, and/or rants about this snippet. I feel this is a very useful bit of code, and hope that others out there may find as much use from it as I will be.

Connect to MySQL db & display result from Table query

I made this script to delete any unneeded files from the server that weren't being used by the database. Of course you can expand this a lot more, but I cut it down a little to put it up here.

This is my MySQL database class that I use for all of my sites. Some included features are:
- Get execution time
- Error reporting (screen and email)
- SQL stats

This is a little function that you can use to print out results of a query. It will dynamicly generate the table for you (like phpMyAdmin). This is a nice little checker that is fast. It beats logging into phpMyAdmin and typing in your query there.

I will use the config.php and class.mysql.php files from MySQL DB Class with Extras, so please look at those also.
