将 foreach 拆分为页面 [英] Split foreach to pages

问题描述

$files = glob('docs/*.xml');
 foreach($files as $file){
 $xml = new SimpleXMLElement($file, 0, true);
 echo'
 <tr>
 <td>' . $xml->doctype . '</td>
 <td><a href="viewdoc.php?docname=' . basename($file, '.xml') . '&username='. $xml->startedby .'&myname='. $_SESSION['username'] .'">' . basename($file, '.xml') . '</a></td>
 <td><a href="viewprofile.php?name='. $xml->startedby .'">'. $xml->startedby .'</a></td>
 <td>'. $xml->date .'</td>
 <td>* * * * *</td>
 <td></td>
 </tr>
 ';
}

上面的代码是一个循环，显示了 docs 文件夹中的所有文件.我希望在 1 页中只有 10 个 xml 文件，并将每页拆分为 10 个文件.我该怎么做?

The code above is a loop that show me all files in docs folder. I wish to have only 10 xml files in 1 page and split every page anouter 10 files. How can I do that?

推荐答案

您可以使用以下方法之一拆分 $files 数组，这两种方法都需要设置一个 $page 变量，该变量将是一个整数，显示哪个10个要查看的xml文件页面.

You can split out the $files array with one of the following , both of these methods require a $page variable to be set that would be an integer showing which 10 xml file page you want to view.

// this will make files an array for 10 element 
$files = glob('docs/*.xml');
$files = array_chunk($files, 10);
foreach($files[$page-1] as $file){ 
$xml = new SimpleXMLElement($file, 0, true);
echo'
    <tr>
    <td>' . $xml->doctype . '</td>
    <td><a href="viewdoc.php?docname=' . basename($file, '.xml') . '&username='. $xml->startedby .'&myname='. $_SESSION['username'] .'">' . basename($file, '.xml') . '</a></td>
    <td><a href="viewprofile.php?name='. $xml->startedby .'">'. $xml->startedby .'</a></td>
    <td>'. $xml->date .'</td>
    <td>* * * * *</td>
    <td></td>
    </tr>
    ';
}

或者你可以使用数组切片来获得你想要的 10 个

Or you could use array slice to get whichever 10 you wanted

$files = glob('docs/*.xml');
$files = array_slice($files, ($page-1)*10, 10);
foreach ($files as $file){
$xml = new SimpleXMLElement($file, 0, true);
echo'
    <tr>
    <td>' . $xml->doctype . '</td>
    <td><a href="viewdoc.php?docname=' . basename($file, '.xml') . '&username='. $xml->startedby .'&myname='. $_SESSION['username'] .'">' . basename($file, '.xml') . '</a></td>
    <td><a href="viewprofile.php?name='. $xml->startedby .'">'. $xml->startedby .'</a></td>
    <td>'. $xml->date .'</td>
    <td>* * * * *</td>
    <td></td>
    </tr>
    ';
}
