According to recent discussions and roadmap updates, WordPress 7.0 (expected around April 2026) will officially drop support for PHP 7.2 and 7.3, while setting <strong>PHP 7.4 as the minimum supported version<\/strong>. The recommended version, however, remains <strong>PHP 8.3<\/strong>.<\/p>\n<p>This isn\u2019t just a technical detail buried in release notes. It directly impacts <strong>security, performance, and long-term stability<\/strong> of every WordPress website. To better understand what this means in practice, we looked at data from <strong>150+ websites under our active maintenance<\/strong>. The result? The market has already started moving.<\/p>\n<h2>What\u2019s Changing in WordPress PHP Requirements?<\/h2>\n<p>WordPress has been gradually raising its PHP requirements for years. The official <a href=\"https:\/\/wordpress.org\/about\/requirements\/\" target=\"_blank\" rel=\"noopener\">WordPress requirements page<\/a> already recommends PHP 8.x for optimal performance and security. At the same time, PHP itself follows a strict lifecycle\u2014once a version reaches end-of-life, it no longer receives security updates. For example, <strong>PHP 7.4 reached end-of-life in November 2022<\/strong>, meaning it no longer receives security fixes. Newer versions like PHP 8.1, 8.2, and 8.3 continue to receive active support and improvements (source: <a href=\"https:\/\/www.php.net\/supported-versions.php\" target=\"_blank\" rel=\"noopener\">php.net supported versions<\/a>).<\/p>\n<p><strong>The direction is clear:<\/strong> WordPress is aligning with modern PHP standards, and older environments will increasingly fall behind.<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"cebhQo4xsf\"><p><a href=\"https:\/\/make.wordpress.org\/core\/2026\/01\/09\/dropping-support-for-php-7-2-and-7-3\/\" target=\"_blank\" rel=\"noopener\">Dropping support for PHP 7.2 and 7.3<\/a><\/p><\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Dropping support for PHP 7.2 and 7.3&#8221; &#8212; Make WordPress Core\" src=\"https:\/\/make.wordpress.org\/core\/2026\/01\/09\/dropping-support-for-php-7-2-and-7-3\/embed\/#?secret=5GfphIsTp2#?secret=cebhQo4xsf\" data-secret=\"cebhQo4xsf\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/p>\n<h2>Real Data: Where 150+ WordPress Sites Actually Stand<\/h2>\n<p>We manage a diverse portfolio of WordPress websites\u2014ranging from small business sites to large-scale platforms. Looking at this dataset gives a realistic picture of where the industry actually is today. <strong>The majority of our clients are already running PHP 8+<\/strong>, with a strong concentration on PHP 8.3 and newer versions.<\/p>\n<p>Based on our internal data (118 actively maintained websites), <strong>over 82% of sites are already running PHP 8+<\/strong>, with <strong>more than 50% on PHP 8.3 or newer<\/strong>. Here\u2019s a simplified breakdown:<\/p>\n<ul>\n<li><strong>PHP 8.3<\/strong> \u2013 37.3% (dominant version across actively maintained sites)<\/li>\n<li><strong>PHP 8.4<\/strong> \u2013 13.6% (fast-growing adoption among newer setups)<\/li>\n<li><strong>PHP 8.1 \/ 8.2<\/strong> \u2013 28% combined (still present, but gradually being phased out)<\/li>\n<li><strong>PHP 7.4<\/strong> \u2013 17.8% (limited to legacy projects or compatibility constraints)<\/li>\n<li><strong>Below PHP 7.4<\/strong> \u2013 0.8% (practically nonexistent in our environment)<\/li>\n<\/ul>\n<p>This confirms an important trend: <strong>the transition has already happened for most actively maintained websites<\/strong>. Those still on older versions are no longer the norm\u2014they are exceptions.<\/p>\n<h2>Why PHP 8.3 Is Becoming the Standard<\/h2>\n<p>The move toward PHP 8.3 isn\u2019t accidental. It\u2019s driven by measurable improvements in both performance and reliability. According to benchmarks and release notes from <a href=\"https:\/\/www.php.net\/releases\/8.3\/en.php\" target=\"_blank\" rel=\"noopener\">PHP 8.3<\/a>, newer versions bring <strong>faster execution, better memory efficiency, and improved error handling<\/strong>. In real-world WordPress environments, this translates into:<\/p>\n<ul>\n<li>faster page load times,<\/li>\n<li>more stable plugin and theme behavior,<\/li>\n<li>reduced server load under traffic.<\/li>\n<\/ul>\n<p>From our own experience, upgrading to PHP 8.x often results in <strong>immediate performance gains without changing a single line of code<\/strong>. <strong>That\u2019s one of the highest ROI improvements you can make on a WordPress site.<\/strong><\/p>\n<h2>What About Sites Still on PHP 7.4?<\/h2>\n<p>There are still cases where sites remain on PHP 7.4. Typically, this comes down to legacy dependencies\u2014older themes, custom plugins, or integrations that haven\u2019t been updated. However, it\u2019s important to understand the risk:<\/p>\n<p><strong>PHP 7.4 is no longer actively supported<\/strong>. This means no security patches, no bug fixes, and increasing compatibility issues over time. As WordPress core, plugins, and hosting providers continue to evolve, these sites will face:<\/p>\n<ul>\n<li>compatibility breaks during updates,<\/li>\n<li>higher vulnerability to security threats,<\/li>\n<li>limited access to modern hosting environments.<\/li>\n<\/ul>\n<p><strong>In short: staying on PHP 7.4 is a temporary workaround, not a long-term strategy.<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-12675\" src=\"https:\/\/wpm.si\/wp-content\/uploads\/2025\/11\/wpm_reference.png\" alt=\"\" width=\"2011\" height=\"1171\" srcset=\"https:\/\/wpm.si\/wp-content\/uploads\/2025\/11\/wpm_reference.png 2011w, https:\/\/wpm.si\/wp-content\/uploads\/2025\/11\/wpm_reference-687x400.png 687w, https:\/\/wpm.si\/wp-content\/uploads\/2025\/11\/wpm_reference-1374x800.png 1374w, https:\/\/wpm.si\/wp-content\/uploads\/2025\/11\/wpm_reference-768x447.png 768w, https:\/\/wpm.si\/wp-content\/uploads\/2025\/11\/wpm_reference-1536x894.png 1536w\" sizes=\"auto, (max-width: 2011px) 100vw, 2011px\" \/><\/p>\n<h2>What We Recommend (Based on 150+ Sites)<\/h2>\n<p>Working with a large number of WordPress installations has helped us refine a clear, practical approach to PHP upgrades.<\/p>\n<ul>\n<li><strong>Standardize on PHP 8.3<\/strong> whenever possible<\/li>\n<li>Keep WordPress core, themes, and plugins regularly updated<\/li>\n<li>Test compatibility before major upgrades<\/li>\n<li>Maintain ongoing monitoring\u2014not just reactive fixes<\/li>\n<\/ul>\n<p>This approach consistently leads to <strong>fewer incidents, better performance, and predictable maintenance costs<\/strong>.
