How to check PHP compatibility? : r/Wordpress
August 25, 2025 - I would recommend switching to PHP 8.3 or even PHP 8.2. From the WordPress PHP versions Compatibility page you can see that WP is only beta-compatible with PHP 8.4. ... Make a backup. Enable WP_DEBUG, WP_DEBUG_LOG in your wp-config.php. Switch the PHP version. Check if there are any errors in wp-content/debug.log ยท If something goes wrong, switch back to an older PHP version. ... Most plugins that are actively maintained should already work fine on PHP 8+, but thereโs no perfect โcheckerโ anymore.
This is a bad idea. PHP 8.2 is supported till Nov 2026.
Well it's "Performance" tag, not security, so it's not wrong. More on reddit.com
Should I update from PHP 7.4 ?
PHP versions below 8.1 are no longer being supported ( https://php.watch/versions ) i.e. if a bug or vulnerability is discovered in 7.4 or 8, it ain't getting fixed. There's not really any reason to NOT upgrade. Recent versions offer performance improvements. You should always be running up to date WP, theme and plugins anyway - if you're running a plugin or theme that requires php 7.4, it's just a matter of time until you're hacked, because the theme/plugin isn't getting patched.

identifying PHP Version from Source Code
No. Why are you asking? You can find out the version being used in Tools > Site Health in the WP Dashboard. End users can't see what version you're running. More on reddit.com
is there a tool to check code from version 8.0 to 8.1? as in what methods might need to be changed
Rector can do this using the "Up to PHP x.y" level sets. You can run it in "dry run" mode if you just want to see what changes would be made. Another tool I've used in the past is the PHPCompatiblity CodeSniffer ruleset, which only detects problems. I don't know what it's like now but last time I checked it didn't have particularly good coverage for recent versions. There's stickies on their issue repo showing known changes that are uncovered.
