Digg Chapter 12. Keeping CurrentPHP, like any other large system, is under constant scrutiny and improvement. Each new version will often include both major and minor changes to enhance security and repair any flaws, configuration mishaps, and other issues that will affect the overall security and stability of your system. Like other system-level scripting languages and programs, the best approach is to update often, and maintain awareness of the latest versions and their changes.

The problem lies in everyday web hosting firms which often seem to employ old versions of PHP. The user is therefore stuck. They may also be at risk as security patches won't be present. Users might also like to use the latest features in PHP5, but the host may still be using PHP4. Hosts might also be running with register_globals on. As reported elsewhere in the comments on this site, when some hosts turned it off, they got several emails about broken scripts. So the hosts simply turned register_globals back on. The only solutions, besides pestering the web host to upgrade, are to change to a different, more modern host, or consider renting a virtual server where you can set up PHP yourself. Of course this is likely to be more expensive and so not suitable for the average person. It just seems a shame to be stuck using older versions of PHP which are less secure than the latest one. me
Agreed, but if they are a decent and respectable web hosting company, they would update PHP regularly and most surely do so if asked.

Another solution could be that the web hosting firms would run a new (virtual) server when a new major PHP version is released. The new server would have all security related settings turned on. This way new customers would automatically get the new features and old ones could ask to be moved. All clients would be informed about the possibility to update, so that the not-so-active web masters could start their slow transition process in the following months. There is of course a downside in this solution too: web hosting firms would need to maintain several PHP version. One way to solve this would be to limit available php versions to two. If for example the host has php4 and php5 servers and then php6 is released, php4 users would be forced to move to the newer version. A major php releases come out once or twice in the year(?) That would give 1-2 years for the slow web masters to adjust ;-) |
