PHP 正则匹配日志信息 并存入数据库

<?php
$DB_logs = Db::name('filelog');
$DB_logs->where('id', '>', 0)->delete();
//逐行读取数据
$file = "./filelogs/u_ex200102.log";
$handle = file($file);
for ($i = 0; $i < count($handle); $i++) {
//    除了正则外 还可以 以空格分开数据
//  日志格式  匹配时完全匹配  注意认真对照
//  $log = '2020-01-02 00:14:09 172.17.79.157 GET /hy/n235.htm - 443 - 23.234.223.202 Mozilla/5.0+(Linux;u;Android+4.2.2;zh-cn;)+AppleWebKit/534.46+(KHTML,like+Gecko)+Version/5.1+Mobile+Safari/10600.6.3+(compatible;+Baiduspider/2.0;++http://www.baidu.com/search/spider.html) 200 0 0 421';
