Question

我有一个CSV文件扫描结果。我只想阅读第一列并阅读第6行的行。

这就是我的尝试：

<html>
<body>
<h1>MAC Address have been verified</h1>

<table width="50%" border="1">
<tr>
    <th>NO</th>
    <th>MAC Address</th>
</tr>

<?php
if (($handle = fopen("data.csv", "r")) !== FALSE) {
    $row = 1;
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        echo "<tr>";
        echo "<td><center>".$row++."</center></td>";
        echo "<td>".$data[0]."</td>";
        echo "</tr>";
    } //end while
    fclose($handle);
} //end if

?>
</table>
</body>enter code here
</html>

以下重要的一行是 if（$ row＆gt; 6）break;

<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        if ( $row > 6 ) break;
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}
?>
