What’s the difference between PHP 5 and PHP 7? What that means is outside of third-party resources, no new development and security updates will be available for any version of PHP that is older than 7.2.

Now in 2020 with version 7.2, support of all older code has been discontinued. In 2014, the decision was made to create standards and while they attempt to preserve compatibility, the original way of coding with PHP has become obsolete. This allowed for websites to be built in any manner the individual developer saw fit, often for good reasons, but not always making the sites accessible for version upgrades. Created in 1994 as open source software, it moved forward without written formal standards until 2014. Similar to our automobile analogy above, PHP has been through its own evolution. Those factors also make it ideally suited for WordPress development, but not limited to that platform. Its use in web development lies largely in its simplicity, making it easy for a newcomer to work with, but also offers advanced options for experienced developers. The client would receive the results of running that script, but would not know what the underlying code was.” “executed on the server, generating HTML which is then sent to the client. “an open source, general purpose scripting language that is especially suited for web development and can be inserted into HTML.” It is not seen or interacted with by website users – but it is critical to making websites work.Īccording to PHP.net, the official PHP website, PHP is PHP is programming that lives “under the hood” of a website. In a nutshell, PHP is a basic building block of many of today’s websites. No one likes the headache that comes with technology updates, but we value our customers and want them to have the best, safest web experience possible. This is the situation we’re facing, and the reason you may be seeing errors, as we transition to the newest version of PHP. The newer code brings safer websites and better customer experiences, but sometimes at the cost of compatibility. Websites and the tools they’re built with also age and become obsolete, as we’ve seen with cars. The same compatibility issues can happen with newer versions of code. Unfortunately, those upgrades often mean that parts from that original Benz wouldn’t be compatible with a modern Mercedes. We’ve seen vast improvements in safety, comfort, and the overall driving experience. The first automobile was invented in 1885 by Karl Benz and though the systems and processes that make our cars run are still very similar, the cars themselves are not. In many ways you can compare your website and its code to the car sitting in your driveway. As capabilities grow and security risks are found, new and better versions are created. The code your website is built on also evolves just like anything else, changing and improving. In fact, the computer I’m typing on doesn’t have a single USB slot. If you think back over the life of computers, they’ve moved from being fed punch cards to using plastic storage disks to now not even having cd-rom drives. Like most things, technology changes over time.
