以下安装mongo-php-driver 也许会遇到
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mongodb.so' - /usr/lib64/php/modules/mongodb.so: undefined symbol: bson_decimal128_from_string in Unknown on line 0

解决问题使用如下：

参数 init前面是 ‘--’，两个半角减号，坑死自己了

Libraries have been installed in:
/home/.../mongo-php-driver/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test’.
[root@www mongo-php-driver]# make install

[root@www mongo-php-driver]# echo "extension=mongodb.so" > /etc/php.d/mongo.ini
[root@www mongo-php-driver]# cat /etc/php.d/mongo.ini
extension=mongodb.so
apache error_log里出现：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mongodb.so' - /usr/lib64/php/modules/mongodb.so: undefined symbol: bson_decimal128_from_string in Unknown on line 0
这个c-driver的问题，mongo也还没暂时没有解决，链接如下：https://jira.mongodb.org/browse/CDRIVER-1173
描述如下：
Since bson_decimal128_from_string () requires a null terminated string, the BSON to JSON conversion for bson_decimal128_t allocates a new string+1 since the input isn't null terminated.
We should be able to avoid that extra malloc, either though stack allocation or passing the length to the bson_decimal128_from_string () function.
---------------------------------------------------------------------------------------
所以变更驱动，使用PECL驱动
