PHP - ZipArchive is enabled but not found

PHP - ZipArchive is enabled but not found References When I look at phpinfo I see that Zip is enabled: extension_loaded(\'zip\') // <- returns true. function_exists(\'zip_open\') // <- returns true. class_exists(\'ZipArchive\', false) // <-returns false. When I try to create a ZipArchive object, I get error: Fatal error: Class \'ZipArchive\' not found PHP Version 5.4.11
