运行时配置

这些函数的行为受 php.ini 中的设置影响。

**Iconv 配置选项**
名字	默认	可修改范围	更新日志
iconv.input_encoding	""	PHP_INI_ALL	自 PHP 4.0.5 起有效。在 PHP 5.6.0 中废弃。
iconv.output_encoding	""	PHP_INI_ALL	自 PHP 4.0.5 起有效。在 PHP 5.6.0 中废弃。
iconv.internal_encoding	""	PHP_INI_ALL	自 PHP 4.0.5 起有效。在 PHP 5.6.0 中废弃。

这是配置指令的简短说明。

Warning

有些系统（比如 IBM AIX）使用 "ISO8859-1" 来代替 "ISO-8859-1"，所以在配置选项和函数参数中必须使用这个值。

iconv.input_encoding string: Warning
This feature has been DEPRECATED as of PHP 5.6.0. Relying on this feature is highly discouraged.

PHP 5.6 及以上的用户应该留空并以 default_charset 取代。

Many people report problems compiling PHP on Leopard due to a libiconv issue.



This may be due to the small C test programme in ./configure.

It calls open_conv with two const * char arguments (correct), but these are NOT valid charsets to iconv. This then breaks ./configure.



AFAIK from the libiconv documentation, the PHP configure call is incorrect: this function expects two valid charset arguments. (You can see a list of valid arguments by running iconv -l).



Changing the call to:



cd = open_conv("UTF-8","ISO-8859-1") 



returns a valid iconv_t number (non-negative), and configure can then continue setting up for your Makefile compile.
