    $handle = fopen($file, "r");

                        <td>Carter</td>
                        <td>johncarter@mail.com</td>
                        <td></td>
           </tr>
             ";
    }
}

fclose($handle);

?>  
</tbody>
</table>

我想读取一些文本文件并将每一行文件内容放入一行表格中。每列都有一个文件。然后我有一列用于删除每一行并删除文件中该行的内容。那我该怎么做呢？

Answer 1

$handle = fopen("other/network/route/via.txt", "r");
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // process the line read.
    }

    fclose($handle);
} else {
    // error opening the file.
}
