Stdlib: ZipArchive class missing — ext/zip read/write API not registered (ext/zip/php_zip.c) #19492
Description
Category
stdlib · php-src-strict · archive extension
Problem
php-src ships ext/zip with the ZipArchive class (open, addFromString, extractTo, …). This compiler has no ZipArchive registration — class_exists('ZipArchive') is false on VM even when the Zend reference build has ext/zip enabled. Apps using .zip iteration/compression cannot run.
