PHP解析Mysql Binlog，依赖于mysql-replication-listener库
详见：
Install MySQL Replication Listener
该源码，有一处bug，在 tcp_driver.cpp 第 650 行处：
int Binlog_tcp_driver::set_position(const std::string &str, unsigned long position)
{
/*
Validate the new position before we attempt to set. Once we set the
position we won’t know if it succeded because the binlog dump is
running in another thread asynchronously.
*/
/*
// 这个地方会导致，如果 set_position 不是最后一个 binlog file，而且 position 又大于最后一个 binlog size，则会返回失败，特此屏蔽掉该判断
if(position >= m_binlog_offset) {
return ERR_FAIL;
}
*/
修改后的 mysql-replication-listener 源码和 php-binlog 源码打包下载地址：
unzip mysql-replication-listener-master.zip
cd mysql-replication-listener-master
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-replication
make & make install
Install php-binlog
unzip php-binlog-master.zip
cd php-binlog-master/ext
/usr/local/php5.5.15/bin/phpize
./configure –with-php-config=/usr/local/php5.5.15/bin/php-config –with-mysql-binlog=/usr/local/mysql-replication
Examples
注：Binlog为行格式
<?php
$link = binlog_connect(“mysql://root:cpyf@127.0.0.1:3306”);
//binlog_set_position($link, 4);
//binlog_set_position($link, 4, ‘mysql-bin.000006’);
while($event=binlog_wait_for_next_event($link)) {
// it will block here
switch($event[‘type_code’]) {
case BINLOG_DELETE_ROWS_EVENT:
var_dump($event);
// do what u want …
break ;
case BINLOG_WRITE_ROWS_EVENT:
var_dump($event);
// do what u want …
break;
case BINLOG_UPDATE_ROWS_EVENT:
var_dump($event);
// do what u want …
break;
default:
// var_dump($event);
break;
}
}
