Decline in usage of unsupported PHP versions
Six months ago, in July 2017, over 80% of all active WordPress websites used unsupported PHP versions. Today only 32% are using old PHP versions. Huge improvement over a short period of time.
Ending the support of PHP 5.5
On July 2017, just before the support of PHP 5.5 was officially ended over 60% of all active WordPress websites used unsupported PHP versions (5.2 – 5.4). With the end of support for PHP 5.5, the stats showed that over 80% of all active WordPress sites used old PHP versions (5.2 – 5.5).
Those were alarming figures! Only 20% of the sites used updated PHP versions (5.6 and 7.0).
Since than, many web hosts upgraded the software running the infrastructure. Some hosts upgraded to PHP 5.6, others upgraded to the cutting edge PHP 7.2. But there was a constant transition to more up-to-date software.
Today, at the end of January 2018, we see a substantial decrease of the usage of old PHP version – only 32% of all active WordPress sites are using unsupported version!!!
The division, more or less, is 32.2% are old PHP versions (5.2-5.4), 40.6% are 5.6 version, and 22.1% for 7.0+ versions. As you can see PHP 5.6 is the dominant version, compare to PHP 5.4 six months ago.
The core team is working on a new project called Server Happy. Just like the Browser Happy project.
While Browser Happy aimed to encourage users to upgrade their browsers (effecting the sites front-end), Server Happy objective is to encourage webhosts to upgrade the back-end of the site.
