libiconv組件安裝好了可以讓我們php支持iconv函數了，這個函數的作用就是字符編碼強制轉換了，下面和111cn小編一起來看一個Linux中安裝libiconv使php支持iconv函數的例子吧。

問題：

線上運行的lamp服務器，php不支持iconv函數。

解決方法：

安裝libiconv，重新編譯apache，使php支持iconv函數，實現utf-8和gb2312編碼的轉換。

具體步驟：

1、下載libiconv

cd /usr/local/src

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz #下載

2、安裝libiconv

cd /usr/local/src

tar zxvf libiconv-1.14.tar.gz #解壓

cd libiconv-1.14 #進入安裝目錄

./configure –prefix=/usr/local/libiconv #配置

make #編譯

make install #安裝

3、重新編譯php

查找系統之前的php編譯參數

cd /usr/local/php/bin #進入php安裝目錄

./php -i |more #查看php編譯參數

如下：

‘–with-pdo_sqlite=shared’ ‘–enable-bcmath=shared’ ‘–enable-ftp=shared’ ‘–enable-mbstring=shared’ ‘–with-iconv=shared’ ‘–enable-sockets=shared’ ‘–enable-zip’ ‘–enable-soap=s

hared’ ‘–with-openssl’ ‘–with-zlib’ ‘–with-curl=shared’ ‘–with-gd=shared’ ‘–with-jpeg-dir’ ‘–with-png-dir’ ‘–with-freetype-dir’ ‘–with-mcrypt=shared’ ‘–with-mhash=shared’ ‘–with-mysql=/ho

me/server/mysql’ ‘–with-mysqli=/home/server/mysql/bin/mysql_config’ ‘–with-pdo-mysql=/home/server/mysql/bin/mysql_config’ ‘–without-pear’ ‘–with-libdir=lib64’

對參數進行修改：

如下

./configure –prefix=/usr/local/php –with-config-file-path=/usr/local/php/etc –with-apxs2=/usr/local/apache/bin/apxs –with-gettext=shared –with-sqlite=shared –with-pdo_sqlite=shared –enable-bcmath=shared –enable-ftp=shared –enable-mbstring=shared –with-iconv-dir=/usr/local/libiconv –enable-sockets=shared –enable-zip –enable-soap=shared –with-openssl –with-zlib –with-curl=shared –with-gd=shared –with-jpeg-dir –with-png-dir –with-freetype-dir –with-mcrypt=shared –with-mhash=shared –with-mysql=/home/server/mysql –with-mysqli=/home/server/mysql/bin/mysql_config –with-pdo-mysql=/home/server/mysql/bin/mysql_config –without-pear –with-libdir=lib64

備注：修改部分

取消原來的–with-iconv=shared

替換為：–with-iconv-dir=/usr/local/libiconv

取消參數兩邊的單引號

其它不變

cd /usr/local/src/php #進入php安裝包目錄(注意php版本要和之前一樣)

./configure –prefix=/usr/local/php –with-config-file-path=/usr/local/php/etc –with-apxs2=/usr/local/apache/bin/apxs –with-gettext=shared –with-sqlite=shared –with-pdo_sqlite=shared –enable-bcmath=shared –enable-ftp=shared –enable-mbstring=shared –with-iconv-dir=/usr/local/libiconv –enable-sockets=shared –enable-zip –enable-soap=shared –with-openssl –with-zlib –with-curl=shared –with-gd=shared –with-jpeg-dir –with-png-dir –with-freetype-dir –with-mcrypt=shared –with-mhash=shared –with-mysql=/home/server/mysql –with-mysqli=/home/server/mysql/bin/mysql_config –with-pdo-mysql=/home/server/mysql/bin/mysql_config –without-pear –with-libdir=lib64 #配置

make #編譯

make install #安裝

4、重啟apache使設置生效

service httpd restart #重啟

故障解決！
