This is an authorize.net credit card processing class. Required elements are:
- Authorize.net account (live and/or sandbox)
- PHP w/ CURL installed
- SSL certificate installed on server
- My Simple Error Class

And use my Easy Credit Card Class as a pre-processor to this class.

For more information on authorize.net just go to their website and download their developers information.

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.

This is a cool function that lets you save MySQL query data to an Excel spreadsheet. This is good for taking a backup or if you want to change a lot of information fast, then re-upload it.

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

Well after searching the internet for something similar to this, I didn't come up with anything...so I made my own! This simple script will track your members' time spent on your website. Please feel free to give comments/suggestions/feedback.

Connect to MySQL db & display result from Table query

This function is useful in helping to deter spam bots by obfuscating things such as e-mail addresses and URLs that are displayed on a web page. While it's not 100% fool proof, it does offer some protection.

Example:
$email = html_entitize('foo@baz.org');
/*
Outputs foo@baz.com
*/

A quick and simple function to dump a variable (array, object, string, int, etc) out into -formatted output for a web browser.

If the variable is an array or an object, you can have it returned into the another variable for later processing (i.e., through templates or e-mail). Due to lack of free time, if the variable is not an array or an object, it will ignore the $return value and print directly to output.

Future revisions will add the above mentioned functionality.

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.

A function that will either read a file or read a string, and parse a random line from it. Very simple.
