PHP Client for Mysql Binlog

PHP解析Mysql Binlog，依赖于mysql-replication-listener库
详见：https://github.com/bullsoft/php-binlog

Install MySQL Replication Listener

• https://github.com/bullsoft/mysql-replication-listener/archive/master.zip

• 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;
    }
  */

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:
