Use of undefined constant INTL_IDNA_VARIANT_UTS46 in 2.10 release #192

Closed onshop closed 7 years ago

Using PHP 5.6.24:

/vendor/zendframework/zend-validator/src/EmailAddress.php:557 Use of undefined constant INTL_IDNA_VARIANT_UTS46 - assumed 'INTL_IDNA_VARIANT_UTS46'

In PHP 5.6.28 the constant is defined.

According to https://3v4l.org/elX65, the constant is available in PHP 5.4.0. I'm guessing the intl extension uses the ICU system lib and your server has a really old version of the ICU lib. Support for UTS 46 Unicode IDNA Compatibility Processing was added in ICU 4.6 and released on 2010-12-02.

Thank you for your assistance @xtreamwayz. We were running a very old ICU lib version.
