这些函数的行为受 php.ini 的影响。
| Name | Default | Changeable | Changelog |
|---|---|---|---|
| iconv.input_encoding | "ISO-8859-1" | PHP_INI_ALL | Available since PHP 4.0.5. |
| iconv.output_encoding | "ISO-8859-1" | PHP_INI_ALL | Available since PHP 4.0.5. |
| iconv.internal_encoding | "ISO-8859-1" | PHP_INI_ALL | Available since PHP 4.0.5. |
有关 PHP_INI_* 常量进一步的细节与定义参见php.ini 配置选项。
Some systems (like IBM AIX) use "ISO8859-1" instead of "ISO-8859-1" so this value has to be used in configuration options and function parameters.
Note: Configuration option iconv.input_encoding is currently not used for anything.
