Each significant arrival of PHP is normally completely bolstered for a long time after its discharge. During that time, bugs and security issues are fixed and fixed all the time.
Bolstered PHP Versions for WordPress

End of life implies these renditions will never again have security support and could be presented to unpatched security vulnerabilities.

This isn’t just awful from a security point of view, yet in addition in light of the fact that there is as yet a huge segment of WordPress destinations that aren’t exploiting the extra execution improvements with PHP 7.
Why the Slow Adoption of Newer Versions?
The fundamental explanation behind the absence of quicker appropriation for new forms no doubt descends a couple of various elements:
The main explanation we see from new clients that move to CSPL is that entrepreneurs don’t have a clue or care about their PHP variant. This, obviously, is reasonable sometimes as we don’t anticipate that everybody should know this. Ordinarily this duty falls on the engineer, office, or host.
It requires some investment for engineers to refresh their code to help more up to date forms of PHP. This incorporates those that create sites, subjects, modules, and so on.
In addition to the fact that it requires exertion and time to refresh code, it likewise can require broad testing to guarantee similarity. The WordPress storehouse alone has more than 49,000 modules!
Numerous WordPress has have been hesitant to push out refreshed PHP adaptations since this could wind up bringing about extra help tickets in the event that it breaks a site. As a WordPress have, we unquestionably get this, however from our experience, this is commonly the a different way. Many help issues we see are from issues brought about by more established PHP variants.
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 as yet not a reason to run on PHP variants that are obsolete, not bolstered, and really could be backing your WordPress site off.

A lof this is because of time requirements and not having the opportunity to test similarity. Things will in the long run break when you run on old variants, and you can see this incident direct in the WordPress gatherings. Here is a typical blunder, which is ordinarily brought about by a more seasoned PHP form and how it treats a specific capacity:
Parse blunder: grammar mistake, startling ” (T_VARIABLE), anticipating capacity (T_FUNCTION) in/bar/file.php on line xxx
You can do a quest in the WordPress gatherings for “surprising T_Function” and it returns more than 2,000 strings, numerous with results from inside the last couple days. Here are only a couple late ones, all because of running old renditions of PHP:

Huge numbers of these strings are being opened because of the way that they are running on obsolete forms of PHP. Be that as it may, the equivalent could likewise be said for strings being open due to PHP 7 similarity issues. Which shows that the WordPress advancement network is as yet attempting to get up to speed with more up to date forms of PHP.
