WORDPRESS RELIABILITY GLOSSARY
PHP Version
The specific release of the programming language powering your WordPress core and plugins.
Plain-English Explanation
The engine that runs your website code. When hosts update PHP (e.g., from 7.4 to 8.2), outdated plugins frequently break.
Systems Engineering Definition
The server-side Zend Engine runtime binary (e.g. PHP 8.1, 8.2, 8.3) executing script opcodes with differing standard library functions and type coercions.
Common Root Causes
- •Host automatic PHP upgrades deprecating functions like create_function() or each()
- •Stricter type signatures in PHP 8 throwing fatal TypeErrors on null arguments
- •Missing required PHP extensions like gd, imagick, or curl
