我怎么能修改它file_get_contents以便它只返回来自 1000 行重复的唯一错误

$this->data['log'] = file_get_contents($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>

错误：

完整代码：在 Jay 的帮助下

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

用。。。来代替：

$input = file_get_contents($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

有一种非常简单的方法可以做到这一点。将错误日志文本设置为$input，然后使用

$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;

仅使用此代码行来获取唯一的错误行

$errors = array();
foreach(file($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];
    }
}
