　　今天在linux上面智障一般搞了好久，本来想安装个swoole的，然后用 php -m 的命令想看下安装的PHP扩展库，发现有的扩展库有的可以出来，有的加载失败，

　　加载失败的错误类型：

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/memcached.so' - /usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/memcached.so: undefined symbol: zend_new_interned_string in Unknown on line 0

　　如下：

[root@pys /]# php -m

上面的意思是：找不到扩展库的路径；这是为什么尼？不是有的扩展库也可以出来吗？

然后我是百度上找各种答案，并不能解决我的问题，最后自己发现问题所在：

因为我并没有为所有的扩展库加了快捷链接，以为在哪里只要用 php -m 的命令就可以查看所有的扩展库。

其实是要：/usr/local/php7/bin/php -m 这个命令才可以，我的是PHP7.0版本的，其他版本自己换下这个路径就好。

如此，就可以看到所有的扩展库了：

[root@pys bin]# /usr/local/php7/bin/php -m
