Avoid "PEAR package PHP_Archive not installed: generated phar will require PHP's phar extension be enabled."

[KEINOS]

The below error/warning appears while building the image/compiling the PHP from source.

$ ./run-updater.sh
...
PEAR package PHP_Archive not installed: generated phar will require PHP's phar extension be enabled.
...

It finishes building with a success though.

In 2007, PHP_Archive was ported to C and released as a PECL extension. The extension was included and enabled by default in PHP 5.3.0.

But PECL's Phar is superseded
