The user agent string of the browser can't be changed by default. But we often see, the logs of website visitors say, user agents were "Google Bot". What is this? Is this a special website browser used by Google? No, This is the website crawler engine of Google. The server where the crawler script is hosted sends this string in the header while sending an http request for crawling your web page. So, it's quite clear that if the visitor of a web page is not a browser (ie. a human user), then the user agent string must be sent by the server software (Apache or IIS or whatever you have). Now in this short tutorial I'll show you how to change the default user agent string of your server using PHP....

This small script will allow you to check if the servers on a website are online or offline.

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...

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.

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....
