An example is with Symfony2 which recommends APC and intl extensions.
In fact intl is required for the FOSUserBundle, if intl is not installed you will get the error: The locale resource bundle could not be loaded for locale "en"
when trying to edit a user profile (e.g. ../../user/user/1/edit)
Use pecl to install the intl extension and then add a:
When doing this you might get the following errors:
[root@spectest php-5.3.4]# pecl install intl downloading intl-2.0.1.tgz ... Starting to download intl-2.0.1.tgz (149,430 bytes) .................................done: 149,430 bytes package.xml version "2.1" is not supported, only 1.0 and 2.0 are supported. Download of "pecl/intl" succeeded, but it is not a valid package archive Error: cannot download "pecl/intl"In this case, upgrade pear, you might need to enter:
pear upgrade -f pear
Note - intl requires libicu. Either download it from site.icu-project.org, or through your package installed (e.g.: yum - package libicu-devel), if using yum it will most likely require icu and libicu as prerequisites.
