igbinary msgpack bson json php中使用

简介

igbinary, mspack, bson在数据格式话，类似json使用


安装igbinary

#git clone https://github.com/igbinary/igbinary.git

#/usr/local/php5.3/bin/phpize

#./configure CFLAGS="-O2 -g" --enable-igbinary --with-php-config=/usr/local/php5.3/bin/php-config
#make
#make install

增加igbinary.so 到php.ini中


安装msgpack

#/usr/local/php5.3/bin/pecl install channel://pecl.php.net/msgpack-0.5.5

增加msgpack.so到 php.ini 中

安装bson
安装mongodb的php driver即可支持


使用

总结：
从运行性能在看来:bson > msgpack > igbinary > navtive > json
从格式话数据大小:igbinary < msgpack < bson < json < navtive
