You should be using the PHP <a href="http://us3.php.net/manual/en/function.error-log.php" rel="nofollow">error_log()</a> function which will respect the php.ini settings.

<pre><code>error_log('Send to PHP error log');

You should be handling your logging better, but to answer your question I'd use the *nix <code>find</code> command.

<code>find /path/to/files* -mtime +5 -delete</code>

This will delete all files that haven't been modified in five days. Adjust to your own needs.

blocks|key|1790854|text|您可以设置服务器调度任务(在*nix系统下称为Cron作业)，以便定期运行并删除左日志文件。任务是执行一段PHP代码来完成这项工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1790855|请参阅Cron职务审查|offset|length|1790856|entityMap|0|LINK|mutability|MUTABLE|url|http://www.thesitewizard.com/general/set-cron-job.shtml^0|0|3|8|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

You can set up a server Scheduled task (most known as Cron Job under *nix systems) to run on a regular basis and delete the left log files. The task would be to execute a PHP code that will do the job.

blocks|key|1790875|text|您可以使用内置函数-+filectime+-跟踪日志文件的创建日期，然后删除那些足够老到可以删除的日志文件。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1790876|此代码搜索日志目录并删除2周前的日志。|1790877|$logs+=+opendir('logs');

You can use a built-in function – <a href="http://php.net/filectime" rel="nofollow"><code>filectime</code></a> – to track the creation date of your log files and then delete those that are old enough to be deleted.

This code searches through the logs directory and deletes logs that are 2 weeks old.

<pre><code>$logs = opendir('logs');

while (($log = readdir($logs)) !== false)
{
 if ($log == '.' || $log == '..')
 continue;

 if (filectime('logs/'.$log) &lt;= time() - 14 * 24 * 60 * 60)
 {
 unlink('logs/'.$log);
 }
}

closedir($logs);
</code></pre>

blocks|key|2269707|text|有两种方法可以解决这个问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2269708|如果只将日志写入一个文件，则可以使用以下内容清空该文件：|ordered-list-item|2269709|如果生成许多文件，就可以编写这样的清理函数：|2269710|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$]]|$1|E|3|F|5|D|7|K|8|@]|9|@]|A|$]]|$1|G|3|-4|5|6|7|L|8|@]|9|@]|A|$]]]|H|$]]

There are two ways you can work it out:

<ol>
<li>if you write the log to only one file, you can empty the file using something like this:

<pre><code>&lt;?php file_put_contents($logpath, "");
</code></pre></li>
<li>if you generate many files, you can write cleanup function like this:

<pre><code>&lt;?php
$logpath = "/tmp/path/to/log/";
$dirh = opendir($logpath);
while (($file = readdir($dh)) !== false) {
 if(in_array($file, array('.', '..'))) continue;
 unlink($logpath . $file);
}
closedir($dirh); 
</code></pre></li>
</ol>

Well, while agreeing with everyone else that you're using the wrong tool for the job, your question is pretty straightforward. So here you go:

<ul>
<li>write a PHP script that will run from the command line</li>
<li>use a tool like <code>cron</code> or windows scheduled task</li>
<li>invoke the <code>cron</code> every minute/five minutes/etc</li>
</ul>

Your script would be pretty straightforward:

<pre><code>&lt;?php
 $dh = opendir(PATH_TO_DIRECTORY);
 while( ($file = readdir($dh)) !== false ) {
 if( !preg_match('/^[.]/', $file) ) { // do some sort of filtering on files
 $path = PATH_TO_DIRECTORY . DIRECTORY_SEPARATOR . $file;
 if( filemtime($path) &lt; strtotime('-1 hour') ) { // check how long it's been around
 unlink($path); // remove it
 }
 }
 }
</code></pre>

You could also use <code>find</code> if you're working in Linux, but I see that @Rawkode posted that while I was writing this so I'll leave you with his elegant answer for that solution.

I'm logging some XML content to a text file using <code>file_put_contents()</code> in case I need it for debugging.

How do I delete this file after a certain amount of time?

I've got a restrictive <code>.htaccess</code> in the log folder, but I'd rather not leave the info (will have customer's addresses, etc) up on the web for long.

可能重复：我正在使用file_put_contents()将一些XML内容记录到文本文件中，以防需要它进行调试。如何在一定时间后删除此文件？我在日志文件夹中有一个限制性的.htaccess，但是我不想把信息(会有客户的地址等)放在网上很长时间。
