我的PHP代码读取日志文件：

<table width="100%" class="table table-striped table-bordered table-hover" id="dataTables-example">
    <thead>
        <tr>
            <th>Sr.No.</th>
            <th>Error</th>
        </tr>
    </thead>
    <tbody>
        <?php
        $cnt = 1;
        if ($file = fopen("RESTAPI/logs/app_errors.log", "r")) {
          while(!feof($file)) {
             $line = fgets($file);
             # do same stuff with the $line
        ?>
        <tr class="odd gradeX">
            <td>
                <?= $cnt ?>
            </td>
            <td>
                <?= $line ?>
            </td>
        </tr>
        <?php $cnt++; }
        fclose($file);
        }?>
    </tbody>
</table>

Answer 1

使用php explode

$arrayOfFields = explode(",", $line);

foreach($arrayOfFields as $field){
  echo $field . " ";
}

这应输出
