【LAMP】Fatal error: Call to undefined function mb_detect_encoding(),该怎么解决

【LAMP】Fatal error: Call to undefined function mb_detect_encoding()

本帖最后由 default7 于 2014-06-15 14:52:48 编辑 我安装LAMP环境，php-xxx-.tar.gz解压缩后的目录 /home/default7/LAMP/php-5.5.13
PHP安装到的目录 /usr/local/php5
然后我安装之后，打开phpmyadmin，报错提示：

<br />Fatal error: Call to undefined function mb_detect_encoding() in /usr/local/apache2/htdocs/phpmyadmin/libraries/php-gettext/gettext.inc on line 177<br />

命令提示行查看php已经安装的模块：mbstring是存在的。

查看phpinfo，相关几个：

<br />PHP Version 5.5.13<br />Configure Command <br />	'./configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mysql' '--prefix=/usr/local/php5' <br /><br />Server API<br /> 	Apache 2.0 Handler<br /><br />Virtual Directory Support<br /> 	enabled<br /><br />Configuration File (php.ini) Path<br /> 	/usr/local/php5/lib<br /><br />Loaded Configuration File<br /> 	/usr/local/php5/lib/php.ini<br /><br />Scan this dir for additional .ini files 	(none)<br />Additional .ini files parsed 	(none) <br />extension_dir<br />	/usr/local/php5/lib/php/extensions/no-debug-zts-20121212<br />	/usr/local/php5/lib/php/extensions/no-debug-zts-20121212<br /><br />

查看php5安装后的extension目录（是空的）：

<br />[[email&#160;protected] ext]# ll /usr/local/php5/lib/php/extensions/no-debug-zts-20121212<br />total 488<br />-rwxr-xr-x. 1 root root 495775 Jun 15 01:01 opcache.so<br />[[email&#160;protected] ext]# ll /usr/local/php5/lib/php/extensions<br />total 4<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 no-debug-zts-20121212<br />

但是在安装后的目录里面另外一个目录却有（目录 /usr/local/php5/include/php/ext）：

<br />[[email&#160;protected] ext]# pwd<br />/usr/local/php5/include/php/ext<br />[[email&#160;protected] ext]# ll<br />total 68<br />drwxr-xr-x. 3 root root 4096 Jun 15 01:01 date<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 dom<br />drwxr-xr-x. 3 root root 4096 Jun 15 01:01 ereg<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 filter<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 hash<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 iconv<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 json<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 libxml<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:02 mysqlnd<br />drwxr-xr-x. 3 root root 4096 Jun 15 01:01 pcre<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:02 pdo<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 phar<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 session<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:01 spl<br />drwxr-xr-x. 3 root root 4096 Jun 15 01:01 sqlite3<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:02 standard<br />drwxr-xr-x. 2 root root 4096 Jun 15 01:02 xml<br />[[email&#160;protected] ext]# <br /><br />

在安装文件夹（/home/default7/LAMP/php-5.5.13/ext）中有mbstring：
