As a perfect example, we&#8217;ve added the new PHP 7.3 to the list of available PHP branches you can use on your SiteGround account. Right now, we support PHP 7.3 RC3, which will be replaced by the final version once it\u2019s released (expected in Dec 2018). So if you write your website code, you can start testing it for the upcoming changes.<\/p>\n\n\n\n<div class=\"post-page__colored-blocks post-page__colored-blocks--update\"><p class=\"text text--size-medium color-darkest\"><strong>PHP 8.4: Stay Updated!<\/strong>\u00a0\ud83d\ude80 Check out our latest blog post to explore the newest features and enhancements in <a href=\"https:\/\/www.siteground.com\/academy\/php-8-4\/\">PHP 8.4<\/a>.<\/p><\/div>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-s-new-in-php-7-3\"><span class=\"ez-toc-section\" id=\"whats-new-in-php-73\"><\/span>What\u2019s New in PHP 7.3?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Most major PHP version updates include syntax changes, new features, and function depreciation. PHP 7.3 follows suit and has all three. If you\u2019re writing code yourself, we strongly recommend that you check the <a href=\"https:\/\/github.com\/php\/php-src\/blob\/php-7.3.0RC3\/UPGRADING\" target=\"_blank\" rel=\"noopener noreferrer\">PHP 7.3 changelog<\/a> in detail, because you may find out a feature or a function you love is now deprecated (sorry).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-does-your-application-support-it\"><span class=\"ez-toc-section\" id=\"does-your-application-support-it\"><\/span>Does your Application Support it?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Most web applications, including WordPress, don\u2019t work on PHP 7.3 yet. According to the official <a href=\"https:\/\/make.wordpress.org\/core\/2018\/10\/03\/proposed-wordpress-5-0-scope-and-schedule\/\" target=\"_blank\" rel=\"noopener noreferrer\">WordPress 5.0 Schedule Post<\/a>, full PHP 7.3 support will be added in the major 5.0 update or in a 4.9.9 release if 5.0 is pushed to January.<\/p>\n\n\n\n<p>That being said, it\u2019s highly recommended that you test new PHP versions on staging copies of your site because even if the core of your web app supports it, some plugins, themes, etc. may still cause issues. Don\u2019t be a cowboy coder &#8212; always test in a staging environment to prevent downtime for your site.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-enable-php-7-3\"><span class=\"ez-toc-section\" id=\"how-to-enable-php-73\"><\/span>How to Enable PHP 7.3?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Enabling PHP 7.3 is as easy as using any other PHP version at SiteGround.
