Runtime Configuration

The behaviour of these functions is affected by
settings in php.ini.

Here’s a short explanation of the configuration
directives.

intl.default_locale string

The locale that will be used in intl functions when
none is specified (either by omitting the corresponding argument or
by passing NULL). These are ICU locales, not system
locales. The built-in ICU locales and their data can be explored at
» http://demo.icu-project.org/icu-bin/locexp.

The default value is empty, which forces the usage
of ICU’s default locale. Once set, the ini setting cannot be reset
to this default value. It is not recommended that this default be
relied on, as its effective value depends on the server’s
environment.

intl.error_level integer

The level of the error messages generated when an
error occurs in ICU functions. This is a PHP error level, such as
E_WARNING. It can be set to
0 in order to inhibit the messages. This does not affect
the return values indicating error or the values returned by
intl_get_error_code() or by the class
specific methods for retrieving error codes and messages. Choosing
E_ERROR will terminate the script whenever an error
condition is found on intl classes.

The default value is 0.

intl.use_exceptions integer

If set to true, an exception will be raised
whenever an error occurs in an intl function. The exception will be
of type IntlException. This is possibly in addition to the
error message generated due to intl.error_level.

The default value is
FALSE.
