Advertising is one way that web site owners can get their visitors to ‘pay’ for the existence of the site. When visitors block the ads then they are not ‘paying’ for their access (those who don’t block the ads but who simply ignore them are paying as they may change their mind if an ad attracts their attention). If you are relying on the advertising to pay for the site then you may wish to know how many of your visitors are blocking the ads.
CURL allows a PHP script to post information to a remote site and get a response back without having to pass control permanently to the other site.
While escaping your data can potentially be as secure as keeping it separate, it isn’t always so in practice. People make mistakes and one possibility if you just escape data is that someone amending the code for some completely separate reason will accidentally remove the code to escape some of the data. This can’t happen when the data is kept completely separate.
Make your mySQL code more secure by using prepare and bind statements to Keep Data Separate from the SQL.

The new version of XHTML has been developed alongside HTML 5 is XHTML 5. Since Internet Explorer 8 is the last browser to not understand XHTML and it doesn’t understand HTML 5 either, XHTML 5 will be the first version of XHTML to become usable at the same time as the equivalent HTML version does.
This XHTML 5 Template provides a starting point for coding pages using XHTML and points out some of the differences from HTML 5 and earlier versions of XHTML.
I often see requests for help from people claiming that their alt tag doesn’t work in Firefox. This statement of course makes no sense whatsoever and just shows that the person has made two mistakes. Firstly they have confused their terminology as it is an attribute and not a tag and secondly they have misunderstood what the attribute is for.

When working out how much it costs to run a web site many people leave out the biggest parts of the actual cost. At least that’s the only reason I can think of for why so many people are trying to save one or two dollars on the cost of their domain name which is the cheapest part of running a site.

Register Globals was deprecated and eventually removed from PHP because it allows ANY variables in your PHP to be able to be overridden by values passed by someone trying to break your script. While just copying any passed GET or POST values to the appropriate variables gets your code working once you turn Register Globals off, it presents the same security hole. By slightly modifying the PHP to only copy those variables that we specify we can maintain the security while provicing a really simple way to copy those valiables that we do want.
