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 ;-)
Être à jour
PHP, comme n'importe quel système de grande taille, est constamment testé et amélioré. Chaque nouvelle version rassemble des modifications majeures et mineures, aussi bien pour renforcer la sécurité, que pour réparer des problèmes de conception et de configuration, ainsi que d'autres points qui peuvent affecter la sécurité et la stabilité globale de votre système.
Comme pour les autres programmes et langages de scripts systèmes, la meilleure approche est de mettre à jour souvent, et de rester à l'écoute des dernières versions et des modifications qu'elles apportent.

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.
