php 匹配apache日志日期的代码

<?php
// Set the default timezone to US/Eastern time:
date_default_timezone_set('US/Eastern');

// Simulate reading an Apache log file, with the following line:
$logline = '127.0.0.1 - - [17/dec/2006:00:26:49 -0800] "GET / HTTP/1.1" 200 41228';

// Since we only want the date section, use regex to obtain it:
preg_match('/\[(.*?)\]/', $logline, $matches);

// Take the date, and convert it:
$timestamp = strtotime($matches[1]);

// Now echo it out again to ensure that we read it correctly:
echo date(DATE_RFC822, $timestamp);
?>
