Solution

The code is as follows:

Wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
Tar-zxvf libiconv-1.13.1.tar.gz
Cd libiconv-1.13.1
./Configure -- prefix =/usr/local/libiconv
Make
Make install

Check php again

The code is as follows:

#. /Configure -- with-mysql =/backup/mysql -- with-freetype-dir -- with-jpeg-dir -- with-png-dir -- with-zlib -- with-curl --- gd -- enable-gd-native-ttf -- with-apxs2 =/usr/local/apache/bin/apxs -- enable-sockets -- with-ic/local/libiconv
# Make
# Make install

Another solution is to remove the iconv module and compile php normally, as shown below:
Too many Makefile is about 77 rows long:
EXTRA_LIBS =...-lcrypt
Add-liconv at the end, for example:
EXTRA_LIBS =...-lcrypt-liconv
Run make again.

The above describes how to add the iconv module for php in linux, including some content, and hope to help those who are interested in the PHP Tutorial.
