Old PHP Versions
Likewise with any bit of programming, PHP has a discharge life cycle in which needs to cling to with the end goal to continue driving things forward and making PHP enhancements. Each real arrival of PHP is regularly completely bolstered for a long time after its discharge. Amid that time, bugs and security issues are settled and fixed all the time.
PHP 5.6 and PHP 7.0 End of Life
As of December 4th, 2018, PHP 7.0 achieves its finish of life. This implies it will never again have security bolster and could be presented to unpatched security vulnerabilities. Sticking to this same pattern, as of December 31st, 2018, PHP 5.6 likewise achieves its finish of life. This formally denotes the finish of a period for PHP 5, as the main rendition, 5.0 was propelled 14 years prior.
As indicated by the authority WordPress Stats page, as of composing this, over 63% of WordPress clients are still on PHP 5.6 or lower. On the off chance that you consolidate this with PHP 7.0, an astounding 82.8% of clients are at present utilizing PHP forms that will never again be upheld come January 2019.
It's considerably scarier on the off chance that you take a gander at the details outside of the WordPress people group. As indicated by W3Techs, PHP 5 is at present utilized by 76.9% of all sites who utilize PHP.
This isn't just awful from a security viewpoint, yet additionally on the grounds that there is as yet a substantial part of WordPress locales that aren't exploiting the extra execution improvements with PHP 7.
Why the Slow Adoption of Newer Versions?
The fundamental purpose behind the absence of quicker selection for new forms in all likelihood descends a couple of various variables:
The main reason we see from new clients that move to particular organisation is that entrepreneurs don't know or care about their PHP variant. This obviously is justifiable at times as we don't anticipate that everybody will know this. Ordinarily this duty falls on the engineer, organization, or host.
It requires investment for designers to refresh their code to help fresher adaptations of PHP. This incorporates those that create sites, subjects, modules, and so forth.
In addition to the fact that it requires exertion and time to refresh code, it can require broad testing to guarantee similarity. The WordPress store alone has more than 49,000 modules!
Numerous WordPress has have been hesitant to push out refreshed PHP renditions since this could wind up bringing about extra help tickets in the event that it breaks a site. As a WordPress have we unquestionably comprehend this, yet from our experience, this is regularly the a different way. Many help issues we see are from issues caused by more established PHP adaptations.
The engineer or organization may be stuck in a difficult situation when managing a customer and other outsider applications they are reluctant to spend assets on refreshing.
In any case, with all that being stated, it is still not a reason to keep running on PHP forms that are obsolete, not upheld, and really could be backing your WordPress site off. Fortunately there is some advancement being made. Jordi Boggiano, prime supporter of Private Packagist, assembles a report every year on PHP use insights. Furthermore, as should be obvious beneath, there is some development forward. This is obviously only an example subset of Composer introduces, yet at the same time fascinating to see the changes.

It is vital to note however, that some working framework sellers still refresh more seasoned forms of PHP on the off chance that they included it.
As indicated by CVE Details, 2016 was one of the most exceedingly awful years for PHP security vulnerabilities, with more than 100 issues revealed.

With the arrival of PHP 7.0 (and 7.2) came immense execution gains! So enormous actually, that it ought to be a need over a great deal of the little enhancements you may playing around with on your WordPress site. The accompanying benchmarks exhibit critical execution enhancements with PHP 7 over its past cycles. PHP 7 enables the framework to execute twice the same number of solicitations every second in correlation with the PHP 5.6, at half of the inactivity.
We likewise ran our own execution benchmarks in 2018 with PHP 5.6 versus PHP 7 versus HHVM. What's more, correspondingly to the benchmarks above, we saw that PHP 7.2 could execute very nearly three fold the number of exchanges (demands) every second when contrasted with PHP 5.6.

A lof this is because of time limitations and not having sufficient energy to test similarity. Things will in the long run break when you keep running on old adaptations, and you can see this event direct in the WordPress discussions.

- Hustle Plugin

A considerable lot of these strings are being opened because of the way that they are running on obsolete variants of PHP. Be that as it may, the equivalent could likewise be said for strings being open due to PHP 7 similarity issues. Which demonstrates that the WordPress advancement network is as yet attempting to make up for lost time with more current adaptations of PHP.
