Ok, another thumbnail PHP function. This function support resize of JPEG and GIF, and resize with aspect ratio (set $THUMBX=0 if you wish it is resized with the Height, $THUMBY=0 if blah blah blah, you get the point)

Format a phone number with php.

The recursive function stripslashesDeep($value) will (upon called) strip slashes (\) from strings and arrays (even arrays with arrays within themself). The controlstatement (if) checks if magic quotes gpc is on, if it is we strip the slashes it have added.

Very good snippet if you want to have the "same" input even if you switch to an enviroment where magic quotes gpc is set to something else than on your originall server.

Database Class with quick connectivity and useful database functio

This snippet will undo all the nasty stuff which happens when you set register_globals to on in your php.ini file.

(Originally found in the code of Wordpress).

This function creates relatively secure random passwords. It's by no means ideal, but it should work in most non-critical situations. The nice thing is the generator attempts to create passwords that people can pronounce and chooses letters that won't be mistaken for others (such as the numeral "1", an upper-case "i" and a lower-case "L"). To keep the code short much of this functionality is very rudimentary, but it's better than nothing.

This function makes URLs in a given text clickable, and shorts down the link text if it's length is over the specified one. (Like vBulletin, etc... does)


PS:
Please explain negative votes, they're pointless otherwise...

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.
