This article will show the SIMPLE use of regular expressions (Perl style/PCRE) to get the values of data delimited by HTML tags. Instead of building a parser that pushes start tags onto a stack and pulls them off once a stop tag is found (if one is found) I find it much easier to use regular expressions. This article is NOT a primer to regular expressions and only shows this particular example....

Using freely available php classes I show how it is possible to download the contact list from Gmail and/or the MSN messenger service (given a username and password) and return this to the user. The user can then select or deselect the contacts they wish to send an email to before submitting the form and sending emails to all their chosen contacts.
This is quite a nice method to `turbocharge` the basic `tell-a-friend` style script. Rather than contacting one friend it is quick and simple to contact fifty or a hundred contacts which means more likely visitors to your site....
Most scripts written for getting a google pagerank connect to the google servers everytime someone views a page where the script is called. Depending on how busy your site is this can mean that you connect to google thousands of times each day to get exactly the same information.
This script uses a cache to prevent this from happening. The first time someone visits your site the script connects to google and then after that the pagerank value is fetched from a cache. This is far faster (my tests suggested about 30 times faster) and requires less bandwidth.
Beyond the benefits in time it is also easy to use and can be used to either fetch a value for the pagerank or generate html code to display an image representing the pagerank...
