PHP解析Mysql Binlog，依赖于mysql-replication-listener库

Install MySQL Replication Listener

• 该源代码，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，假设 set_position 不是最后一个 binlog file，并且 position 又大于最后一个 binlog size，则会返回失败，特此屏蔽掉该推断
 if(position >= m_binlog_offset) {
 return ERR_FAIL;
 }
 */ 

• 改动后的 mysql-replication-listener 源代码和 php-binlog 源代码打包下载地址：

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;
 }
}
