PHP 7.3 – now available

No Comments

PHP 7.3 is now available across all hosting and MultiDomain accounts.  It can be selected from your control panel.

PHP History

Originally released in 1994 by Rasmus Lerdorf, as Personal Home Page Tools, later shortened to PHP.  By 1998 an estimated 1% of web servers were able to process php scripts.  Our first web servers, back in 1999, ran PHP 4 – switching to the Zend Engine the following year.

2004 saw the release of PHP 5 and also WordPress 1.0.  This combination of PHP and WordPress now represents over 1/3 of our hosted websites and dwarfs any other combination.  PHP 7.3 and WordPress 5.1 as available today, offers the fastest and most powerful combination to date.

Let’s take a brief look at some of the differences thats this new version offers:

Speed

Of course, this depends on your use case, but PHPBench is showing 7.3 to be almost 10% faster than 7.2, 31% faster than 7.0 and almost 3x the speed of 5.6 for those lingering on this old version. (source)

What’s changed?

PHP have released details of the changes in this minor version, available here.

The most talked about features are:

  • improvements to the heredoc and nowdoc syntaxes, which make the code more human-readable and easier to nest.
  • trailing comma in function calls, these were already permitted in arrays and make code appear cleaner and easier to edit.
  • support for Argon2 for password hashing.
Compatibility

Most of the commonly used software amongst our users have announced PHP 7.3 compatibility, including:

However, Magento is yet to be compatible, so hold back with that.
