PHP character encoding related function iconv

This module contains the interface for the iconv character set conversion function. Using this module, you can convert a string expressed in a local character set to another character set, such as the Unicode character set. Supported character sets are based on the implementation of iconv on your system. Note that on some systems the iconv function may not work as you expect. In this case, it would be a good idea to install the libiconv library. It will ultimately produce more consistent results.

Since PHP 5.0.0, it is equipped with this extension with various practical functions to help you write multi-language scripts.

This extension is activated by default, but it can be disabled at compile time with the --without-iconv option.

Option command --with-iconv-dir is used to specify the path of iconv in the system when compiling PHP, otherwise the default path will be scanned.
