Should You Use PHP 7?
PHP 7.1 was discharged at the end of 2016, a year after the revealing of PHP 7.0
(The programming language, used largely in web development, is more than 20 years old—ancient, by
tech-world standards.) Yet according to some sources, adoption of PHP 7.0 has been genuinely
modest, despite its status as a major release.

That slow uptake aside, PHP 7.0 is vastly improved than past emphases at sort handling, specifying
types for function returns, and error handling. There are also notable improvements in the comparison
operator (the spaceship operator <=>) as well as the null coalesce (as in C#) that gives a non-invalid
default. Add to this zero-cost statements (expectations), integer divisions (intdiv(n,d) ), and
cryptographically-secure random numbers, and you have a language strong enough to deal with an
assortment of tasks.

PHP 7 Uptake
According to PHP training in Chandigarh, PHP powers 82.6 percent of server-scripted sites; under
5 percent of those PHP-powered websites, however, use PHP 7—the rest depends on a blend of
PHP 4 and 5 (note that PHP 6 was never released due to an unsuccessful attempt to include
Unicode; it wound up with such a terrible reputation that the developers chose “7” as the number
of the next release).

Why the slow uptake? There are a few possible reasons.
PHP’s Backwards-Incompatible Changes
The official PHP site includes a long page that separates the backward incompatibilities between
PHP 5.6 and PHP 7. That’s in addition to the list of deprecated features in PHP 7.0.x, which could
make it hard for certain developers to upgrade to the latest version of PHP. Also, recollect,
breaking an imperative customer's site could without much of a stretch put an improvement firm out
of business.

breaking an imperative customer's site could without much of a stretch put an improvement firm out

For instance, if your site utilizes the MySQL expansion and functions that begin with MySQL_, you
are in trouble: that’s not built into PHP 7.0, and was deprecated from PHP 5.5 onwards.

Hosting companies detected PHP's depreciation and versioning issues a few years back, and many
shifted responsibility to website owners by giving a selectable scope of PHP versions. A few may have
caveats in their contracts that reflect this, i.e., “If you change your version of PHP and your site
breaks, it's your problem." If you work with PHP, it may work with PHP, it might be worth taking
another look at your paperwork to make sure.

So if developers aren’t changing to PHP 7.0.x in huge numbers since they're afraid that doing so
will wreck their existing work, what can they do?

A Brief Aside: Open-Source Installers
A fast side-note here for open-source developers: there are commercial third-party installers for
open-source packages in PHP, which in turn are licensed to hosting companies. These include
Installatron, Fantastico, and Softaculous. They include an incentive by enabling the user to install any of
over 200 open-source packages, saving an immense amount of labor and time. The convenience of
being able to rapidly include packages from your site makes attempting any of these a delight.

But here, PHP 7 raises its head once more: it will take time for all of these packages to turn out to be
completely compliant. For example, Installatron has said it doesn’t support PHP 7.0/7.1 yet; it may take
some time for others like Fantastico to do so, as well.

Caution
Technically, PHP 7 was an important release; Additional speed is definitely helpful. Consider that, with
PHP 5.6 on shared hosting, I’ve timed a basic PHP website page at 100 microseconds; PHP 7 may
chop that time in half. This acceleration will help increasingly complex PHP sites, even when you take
into account the added time that the browser needs to fetch page components, for example, jQuery and
CSS.

For its part, WordPress suggests that changing to PHP 7 (something it recommends, although the
platform will keep running on prior PHP versions) will yield a speed increment of up to 70 percent, which
thus will help improve your Google indexed lists (which worth quicker page-load times).

Given what a number of sites depend on it, PHP is a vital language for many developers to know.
However, those tech pros running older websites might need to utilize some caution before upgrading to
PHP 7; although this latest version offers some great advantages, there are additionally some
compatibility issues. That’s not to say you shouldn’t upgrade, but prepare for potentially a lot of work if
you do.
