需求

To build the extension you need to install the » ICU library, version 4.0.0 or newer is required. As of PHP 7.4.0 ICU 50.1 or newer is required.

This extension is bundled with PHP as of PHP version 5.3.0. Alternatively, the PECL version of this extension may be used with all PHP versions greater than 5.2.0 (5.2.4+ recommended).

安装

This extension may be installed using the bundled version as of PHP 5.3.0, or as a PECL extension as of PHP 5.2.0. In other words, there are two methods to install the intl extension.

安装此 PECL 扩展相关的信息可在手册中标题为 PECL 扩展的安装章节中找到。更多信息如新的发行版本、下载、源文件、 维护人员信息及变更日志等，都在此处： » https://pecl.php.net/package/intl.

Alternatively, --enable-intl will enable the bundled version while compiling PHP.

If your ICU is installed to a non-standard directory then you might want to specify its location in LD_LIBRARY_PATH environment variable so that dynamic linker can find it:

$ export LD_LIBRARY_PATH=/opt/icu/lib

Otherwise, if PHP and ICU are installed to their default locations, then the additional options to `configure' are not needed.

运行时配置

这些函数的行为受 php.ini 中的设置影响。

这是配置指令的简短说明。

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 int
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 <span class="function">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 int
If set to true, an exception will be raised whenever an error occurs in an intl function. The exception will be of type <span class="classname">IntlException. This is possibly in addition to the error message generated due to intl.error_level.

The default value is false.
