Why There Is A Need To Upgrade Website To PHP 7?

Here are the top reasons explaining why you need to upgrade your website to PHP 7+ as soon as possible:

1. Enhances speed and performance

If your site is still running on the older version of PHP, updating to the latest version will give you fast performance gain. When PHP 7.0 was introduced, it was universally appreciated for giving substantial performance gains. The official benchmarking uses WordPress 4.1.1 that shows PHP 7.0 allows servers to perform at par as many requests per second comparatively.

Recently, the popular web host Kinsta issued performance benchmarks, analyzing PHP 5.6, PHP 7.0, PHP 7.1, PHP 7.2, and PHP 7.3. Their conclusions show PHP 7.3 performs thrice as many requests per second as compared to PHP 5.6.

As we know that for any software, developers will only maintain older versions for a specific timeframe. For instance, outdated versions of the iPhones aren’t compatible with the latest version of iOS.

This rolls down to the fact that supporting old software and ensuring backward compatibility actively is expensive, often in terms of time for theme developers and plugins. It is essential that you move forward with implementing new features, security patches, and performance enhancements to your website. To make this happen, you can hire dedicated PHP programmers to upgrade your website to the latest PHP version.

3. Security

Another top reason why you should upgrade your website is security. Running the latest version of PHP assures that your site is secured against vulnerabilities recognized in older versions of PHP.

For instance, the popular Security vulnerability Datasource CVE details reveal, there were, unfortunately, 18 acknowledged vulnerabilities found in PHP this year. Subsequently, there were 43 security exploits found in 2017, and in 2016 107 vulnerabilities were detected.

These vulnerabilities include code execution, DoS, SQL injection, XSS, and many other kinds of exploits.

How can enterprises upgrade to the latest version of PHP?
