PHP的gzuncompress与文件读写错误 [英] PHP gzuncompress with file read and write errors

问题描述

我有一个跟踪通过脚本发生的事件的函数。为了有效地使用我的资源，我决定压缩它生成的数据。然而，我不断收到此错误：

$ p $ 未知的错误类型：[2] gzuncompress（）[function.gzuncompress]：数据错误


以下是函数：

pre > function eventlog（$ type，$ message）{
//类型：账户，运行，队列，系统
//设置文件名/位置
$ eventfile ='/myprivatedirectory/'.date('Ymd').$type.'.log';
$ b $ if（file_exists（$ eventfile））{
while（！is_writable（$ eventfile））{clearstatcache（）;}

$ fh_log = fopen（$ eventfile， 'R +'）;
flock（$ fh_log，LOCK_EX）;
$ logcontents = gzuncompress（fread（$ fh_log，filesize（$ eventfile）））;

倒带（$ fh_log）;
ftruncate（$ fh_log，0）;

$ logcompressed = gzcompress（$ logcontents。$ message。\\\
）;
fwrite（$ fh_log，$ logcompressed）;
flock（$ fh_log，LOCK_UN）;
fclose（$ fh_log）;
} else {
$ fh_log = fopen（$ eventfile，'w'）;
flock（$ fh_log，LOCK_EX）;
$ logcompressed = gzcompress（$ message。\\\
）;
fwrite（$ fh_log，$ logcompressed）;
flock（$ fh_log，LOCK_UN）;
fclose（$ fh_log）;






$ b因此，每天午夜，一个新的错误日志是创建任何上述事件发生（帐户，运行，队列，系统），否则每个新的事件追加到尊重的日志文件。

我很想保持压缩，但我不能有这些错误，任何人都可以请帮忙？感谢提前。
解决方案

我认为执行是错误的我不会建议你gzcompress（$ message。\ N）;每一条消息...

我认为你应该做的就是在一天结束的时候你可以压缩整个日志文件，这样更有效率。

使用

  file_put_contents 
  
  
 
 
 $ p  $ eventfile ='/myprivatedirectory/'.date('Ymd').$type.'.log'; 
 $ eventfileCompressed ='/myprivatedirectory/'.date('Ymd').$type.'.gz'; 
 $ gz = gzopen（$ eventfilecompressed，w9）; 
 gzwrite（$ gz，file_get_contents（$ eventfile））; 
 gzclose（$ gz）; 
  

阅读文件

  $ zd = gzopen（$ eventfilecompressed，r）; 
 $ zr = gzread（$ zd，$ fileSize）; 
 gzclose（$ zd）; 
  

这种方法可以为您节省更多的处理能力

I have a function that keeps track of events that happen through out the script. In an effort to use my resources effectively, I decided to compress the data that it generates. However, I keep getting this error:

Unknown error type: [2] gzuncompress() [function.gzuncompress]: data error

Here's the function:

function eventlog($type, $message){
    // Types: account,run,queue,system
    // Set up file name/location
    $eventfile = '/myprivatedirectory/'.date('Ymd').$type.'.log';

    if(file_exists($eventfile)){
        while(!is_writable($eventfile)){clearstatcache();}

        $fh_log = fopen($eventfile,'r+');
        flock($fh_log, LOCK_EX);
        $logcontents = gzuncompress(fread($fh_log,filesize($eventfile)));

        rewind($fh_log);
        ftruncate($fh_log, 0);

        $logcompressed = gzcompress($logcontents.$message."\n");
        fwrite($fh_log,$logcompressed);
        flock($fh_log, LOCK_UN);
        fclose($fh_log);
    } else {
        $fh_log = fopen($eventfile,'w');
        flock($fh_log, LOCK_EX);
        $logcompressed = gzcompress($message."\n");
        fwrite($fh_log,$logcompressed);
        flock($fh_log, LOCK_UN);
        fclose($fh_log);
    }
}

So everyday, at midnight, a new error log is created as any of the above events occur (account,run,queue,system), otherwise each new event is appended to the respectful log file.

I would love to keep the compression, but I can not keep having these errors, can anyone please help? Thanks in advance.

解决方案

I think the implementation is all wrong i would not advice you to gzcompress($message."\n"); every message ...

I think what you should do is that at the end of the day you can compress the whole log file which is more efficient

Save your information using

  file_put_contents

At the end of the day

$eventfile = '/myprivatedirectory/'.date('Ymd').$type.'.log';
$eventfileCompressed = '/myprivatedirectory/'.date('Ymd').$type.'.gz';
$gz = gzopen($eventfileCompressed ,"w9");
gzwrite($gz, file_get_contents($eventfile));
gzclose($gz);

To read the file

$zd = gzopen($eventfileCompressed,"r");
$zr = gzread($zd,$fileSize);
gzclose($zd);

This approach would save you more processing power
