PHP is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML which is why most of the Content Management Systems like WordPress, Magento, Drupal, Joomla etc use PHP. It is not just limited to such site, but a lot of Opensource applications like SugarCRM, osTickets, etc use PHP for their application. TD Web Services provides over 1 Click 400+ PHP Based Applications/scripts within our Business Hosting.

WHY UPGRADE TO PHP 7.2?

1. IT’S CRAZY FAST

Stats! Stats! Stats! will give us tangible results. Just don’t take our word for it. PHP Performance tests were done on a Tyan 2U server with AMD EPYC 7601 processor and running Ubuntu 17.10 with the Linux 4.13 kernel.

2. MORE CONTROL OVER TYPE DECLARATIONS

PHP doesn’t require you to declare your variable type, it takes it automatically. This helps to code faster but also results in errors; because it doesn’t always catch if you’re mixing things up. With PHP 7, you can override the assumptions and declare your own variable with some super useful new techniques, giving you more control and cleaner code.

3. BETTER ERROR HANDLING

All PHP developers dread White Screen of Death. Previously PHP will stop working as soon as it encounters an error. With PHP 7 it enable you to write exceptions for some of the errors and catch those exceptions. This will not allow the script to shut itself down. Your website or application will keep on working.

4. MANY OTHER FEATURES

There are a lot of other features, like support for emoji’s, new operators, better security with CSPRNG (basically using OS’s Random Number Generator – used for Salting of passwords).

PHP 7.2 has released officially with new features, functions and several smaller core improvements. PHP 7.2 has come with some new security functions and language legacy clean ups. it provides a big performance boost and it is faster than PHP 7. Here I will describe about the new released features that are mentions as below.

PHP 7.2 features

Parameter type widening

Abstract class Parameter type widening

Trailing comma in list syntax

Object Type Hinting

New Sodium extension

Argon2 in password hash

As we known, PHP 7 introduced a big performance improvement compared with PHP 5. The benchmarks reported an average improvement of 2x for the execution time and a great reduction of the memory consumption 10x in some cases.

This performance boost took PHP to be one of the fast interpreted language in the world.

PHP 7.2 introduces again some performance improvement. According to the benchmark published by Michael Larabel, PHP 7.2 is 20% faster than 7.0 and 10% faster than 7.1

PHP 7.2 introduces the usage of the object type. This new scalar type can be used to represent PHP objects.

When we look at official Stats of WordPress, it is quite a surprise that around 40% of WordPress are still using PHP 5.6. When we discussed with various WordPress site owners, it was mentioned to us that most of them are not aware which PHP version was provided by their hosting providers. Which is basically – that most of the Hosting Providers are not providing proper PHP Version that will help to speed up your site.

This is a comparison of the WordPress page load speed. This isn’t the whole page loading in the browser, it’s just the php dynamic portion. Whilst this is just against 1 site, the relative performance will be indicative regardless of site design , templates and images.
