blocks|key|1732116|text|有一大堆php脚本可以做到这一点，只要在谷歌上搜索一下就知道了。如果你想使用你自己的文件，这并不比读取任何其他文件更复杂。只需确保您知道日志文件(在httpd.conf文件中定义)和format+your+log+files的位置。该格式也在httpd.conf中定义|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1732117|entityMap|0|LINK|mutability|MUTABLE|url|http://httpd.apache.org/docs/2.0/logs.html^0|2J|L|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

there are piles of php scripts that do this, just do a google search for examples. if you want to roll your own, it's nothing more complex than reading any other file. just make sure you know the location of your logfiles (defined in the httpd.conf file) and the <a href="http://httpd.apache.org/docs/2.0/logs.html" rel="nofollow noreferrer">format your log files</a> are in. the format is also defined in httpd.conf

blocks|key|1732147|text|对于其他正在寻找示例脚本的人来说，我把一些东西组合在一起，它有基本的东西：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1732148|<?php

for anyone else looking for a sample script, i threw something together, it's got the basics:

<pre><code>&lt;?php

?&gt;
&lt;Table border="1"&gt;
 &lt;tr&gt;
 &lt;th&gt;Date&lt;/th&gt;
 &lt;th&gt;Type&lt;/th&gt;
 &lt;th&gt;Client&lt;/th&gt;
 &lt;th&gt;Message&lt;/th&gt;
 &lt;/tr&gt;
&lt;?
 foreach($output as $line) {
 // sample line: [Wed Oct 01 15:07:23 2008] [error] [client 76.246.51.127] PHP 99. Debugger-&gt;handleError() /home/gsmcms/public_html/central/cake/libs/debugger.php:0
 preg_match('~^\[(.*?)\]~', $line, $date);
 if(empty($date[1])) {
 continue;
 }
 preg_match('~\] \[([a-z]*?)\] \[~', $line, $type);
 preg_match('~\] \[client ([0-9\.]*)\]~', $line, $client);
 preg_match('~\] (.*)$~', $line, $message);
 ?&gt;
 &lt;tr&gt;
 &lt;td&gt;&lt;?=$date[1]?&gt;&lt;/td&gt;
 &lt;td&gt;&lt;?=$type[1]?&gt;&lt;/td&gt;
 &lt;td&gt;&lt;?=$client[1]?&gt;&lt;/td&gt;
 &lt;td&gt;&lt;?=$message[1]?&gt;&lt;/td&gt;

Here's a small-ish class that makes it easy to read a number of characters from the back of a large file w/o overloading memory. The test setting lets you see it in action cannibalizing itself.

<pre><code>BigFile.php
&lt;?php
$run_test = true;
$test_file = 'BigFile.php';

class BigFile
{
private $file_handle;

/**
 * 
 * Load the file from a filepath 
 * @param string $path_to_file
 * @throws Exception if path cannot be read from
 */
public function __construct( $path_to_log )
{
 if( is_readable($path_to_log) )
 {
 $this-&gt;file_handle = fopen( $path_to_log, 'r');
 }
 else
 {
 throw new Exception("The file path to the file is not valid");
 } 
}

/**
 * 
 * 'Finish your breakfast' - Jay Z's homme Strict
 */
public function __destruct()
{
 fclose($this-&gt;file_handle); 
}

/**
 * 
 * Returns a number of characters from the end of a file w/o loading the entire file into memory
 * @param integer $number_of_characters_to_get
 * @return string $characters
 */
public function getFromEnd( $number_of_characters_to_get )
{
 $offset = -1*$number_of_characters_to_get;
 $text = "";

 fseek( $this-&gt;file_handle, $offset , SEEK_END);

 while(!feof($this-&gt;file_handle))
 {
 $text .= fgets($this-&gt;file_handle);
 }

 return $text;
}
}

if( $run_test )
{
$number_of_characters_to_get = 100000;

I want to create a script that parses or makes sense of apache's error log to see what the most recent error was. I was wondering if anyone out there has something that does this or has any ideas where to start?

How can I parse Apache's error log in PHP?

日志文件

我想创建一个脚本来解析或理解apache的错误日志，以查看最近的错误是什么。我想知道有没有人能做到这一点，或者有什么想法从哪里开始？
