这是我的php代码:从Mysql中检索一个表并将其打印在页面上。

代码:

<?php

// Inialize session
session_start();

// Check, if username session is NOT set then this page will jump to login page
if (!isset($_SESSION['username'])) {
header('Location: index.php');
}

?>

    echo "<td>$row[0]</td>";
    echo "<td>$row[1]</td>";
    echo "<td>$row[2]</td>";
    echo "<td>$row[3]</td>";
    echo "</tr>\n";
}
echo "</table></div>";
?>


</body>
</html>

基本上看起来有点像这样:

Sql table

我需要的是此页面上的一个按钮,点击该按钮将同一个表格下载为PDF文件。

任何帮助都将不胜感激。

将html轻松转换为pdf的唯一可行解决方案是使用domPdf库https://code.google.com/p/dompdf/

您可以使用?pdf get参数添加指向同一页面的链接,并在$_GET['pdf']出现时通过dompdf输出您的php代码,而不是将其回显到浏览器。

查看wiki的用法: https://code.google.com/p/dompdf/wiki/Usage

我认为在您的情况下最简单的方法是添加: if ( $_GET['pdf'] ) ob_start(); 到页面顶部。 (启动输出缓冲区:请参阅http://php.net/manual/en/function.ob-start.php

if ( $_GET['pdf'] ) {
    $html = ob_get_contents(); // this fills $html with all your output generated above.

    //do the dompdf stuff here , using the $html variable.

}

到页面底部..
