Opencart的錯誤日誌顯示獨特的錯誤

我怎麼能修改file_get_contents，使其只從1000返回重複Opencart的錯誤日誌顯示獨特的錯誤

行的唯一錯誤

$this->data['log'] = file_get_contents($file, FILE_USE_INCLUDE_PATH, null); 

<textarea wrap="off" style="width: 98%; height: 300px; padding: 5px; border: 1px solid #CCCCCC; background: #FFFFFF; overflow: scroll;"><?php echo $log; ?></textarea>

錯誤：

完整代碼：與幫助周杰倫

$this->data['log'] = file_get_contents($file, FILE_USE_INCLUDE_PATH, null);

替換：

條

$input = file_get_contents($file, FILE_USE_INCLUDE_PATH, null); 
$temp = preg_replace('~\d{4}-\d\d-\d\d \d\d?:\d\d:\d\d - ~', '', $input); 
$this->data['log'] = implode(PHP_EOL, array_unique(explode(PHP_EOL, $temp)));

vqmod

<file name="admin/controller/tool/error_log.php"> 
    <operation> 
     <search position="before"><![CDATA[ 
     $this->data['clear'] = $this->url->link('tool/error_log/clear', 'token=' . $this->session->data['token'], 'SSL'); 
     ]]></search> 
     <add><![CDATA[

有這樣做的一個非常簡單的方法。設置你的錯誤日誌文本爲$input，然後使用

$temp = preg_replace('~\d{4}-\d\d-\d\d \d\d?:\d\d:\d\d - ~', '', $input); 
$output = implode(PHP_EOL, array_unique(explode(PHP_EOL, $temp))); 

echo $output;

+1非常印象如此之短。 –

周杰倫，你有（或知道我在哪裏可以找到它）和VQMod這個修復文件？我無法在谷歌上找到它... – Mathlight

@Mathlight - 這實際上是你需要一個vQmod的東西。你只需要一個php文件，並用我看到的日誌文件 –

使用此代碼行只拿到唯一的錯誤線

$errors = array(); 
foreach(file($file)) as $error_line) { 
    $regex = '/^([0-9]{4}-[0-9]{2}-[0-9]{2}\s[0-9]{2}:[0-9]{2}:[0-9]{2})\s-\s(.+)$/'; 
    preg_match($regex, $error_line, $match); 

    $hash = md5($match[2]); 

    if (!isset($errors[$hash])) { 
     $errors[$hash] = array(
      'error_line' => $match[2], 
      'times' = array(
       $match[1], 
      ), 
     ); 
    } else { 
     $errors[$hash]['times'][] = $match[1]; 
    } 
}

我不認爲它會去工作，除非你剝去每一行的時間戳。 –

這就是我改變了我的答案 – GreenRover

正則表達式會拋出一個錯誤，因爲它沒有任何分隔符 –
