Mysql IP地址转换：

将IP地址转化为数字: SELECT inet_aton('192.168.1.139');

将数字转化为IP地址: SELECT inet_ntoa(3525181543);

时间整型转换日期型：SELECT FROM_UNIXTIME(1320423419); 2011-11-05 00:16:59

时间日期型转换整型：SELECT UNIX_TIMESTAMP("2011-11-05 00:20:00"); 1320423600

select UNIX_TIMESTAMP("2013-07-01 00:00:00");
1372608000

select UNIX_TIMESTAMP("2013-09-01 00:00:00");
1377964800

5356800L * 1000

长整型相算法必须加L

//ip转为正整数

function ip2longM($ip){
//sprintf("%u", ip2long($ip));
return bindec(decbin(ip2long($ip)));
}
