请问 这样一个日志文件 怎么用PHP代码解析 怎么实现输出有多少个ip访问（总访问量，有多少个不同的IP访问（数量） 怎么实现一分钟内有多少访问量？ 求大神代码示例啊，实在不知从何下手写..... 

回复讨论(解决方案)

假定你的这些数据存放于 log.txt 中
那么

$a = file('log.txt');foreach($a as $r) {  $t = preg_split('/[- ["]+/', $r);  $d[] = array(    'ip' => $t[0],    'date' => strtotime(preg_replace('/[\/:]/', ' ', $t[1], 3)),    'target' => $t[4],    'mode' => $t[6],    );}var_export($d);

将得到这样的数组

array (  0 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445186,    'target' => '/favicon.ico',    'mode' => '404',  ),  1 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445186,    'target' => '/admin/d1/cl',    'mode' => '200',  ),  2 =>   array (    'ip' => '192.168.1.106',    'date' => 1448445209,    'target' => '/admin/d1/post_pd',    'mode' => '200',  ),  3 =>   array (    'ip' => '192.168.1.106',    'date' => 1448445353,    'target' => '/admin/d1/post_id?pid=1&rid=1&imgname=1.jpg',    'mode' => '200',  ),  4 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445459,    'target' => '/admin/d1/post_irimg',    'mode' => '200',  ),  5 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445795,    'target' => '404',    'mode' => 'Mozilla/5.0',  ),  6 =>   array (    'ip' => '192.168.1.105',    'date' => 1448502790,    'target' => '/admin/V1/post_id',    'mode' => '200',  ),)

应该知道该怎么做了吧？
自己得动动脑子的！

好的好的，谢谢大神的教诲  我先去研究看一下，谢谢！  

可以使用工具实现，例如：LogAnalyzer

大神我拿出时间date了 可是不知道怎么实现每分钟有多少访问啊？

$data = array (  0 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445186,    'target' => '/favicon.ico',    'mode' => '404',  ),  1 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445186,    'target' => '/admin/d1/cl',    'mode' => '200',  ),  2 =>   array (    'ip' => '192.168.1.106',    'date' => 1448445209,    'target' => '/admin/d1/post_pd',    'mode' => '200',  ),  3 =>   array (    'ip' => '192.168.1.106',    'date' => 1448445353,    'target' => '/admin/d1/post_id?pid=1&rid=1&imgname=1.jpg',    'mode' => '200',  ),  4 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445459,    'target' => '/admin/d1/post_irimg',    'mode' => '200',  ),  5 =>   array (    'ip' => '192.168.1.105',    'date' => 1448445795,    'target' => '404',    'mode' => 'Mozilla/5.0',  ),  6 =>   array (    'ip' => '192.168.1.105',    'date' => 1448502790,    'target' => '/admin/V1/post_id',    'mode' => '200',  ),);foreach($data as $v) @$r[date('Y-m-d H:i', $v['date'])]++;print_r($r);

Array(    [2015-11-25 17:53] => 3    [2015-11-25 17:55] => 1    [2015-11-25 17:57] => 1    [2015-11-25 18:03] => 1    [2015-11-26 09:53] => 1)
