As of PHP 7.4.0, in order to use these functions you must compile PHP with zip support by using the --with-zip configure option. Previously, zip support had to be enabled by using the --enable-zip configure option. As of PHP 7.4.0, the bundled libzip is removed.
As of PHP 7.3.0, building against the bundled libzip is discouraged, but still possible by adding --without-libzip to the configuration.
A --with-libzip=DIR configure option has been added to use a system libzip installation. libzip version 0.11 is required, with 0.11.2 or later recommended.
This extension is built-in.
