如何在显示文本文件内容时设置页码
how can i set page number in showing contents of text file
我有文本文件,我想显示页码以便在页面中显示
例如我的文本文件有 100 行,我可以用 table 中的数组显示它们,一行中的每一行如下所示:
这是我的文本文件示例:
mycontent-54564-yoursdsd
condsadtent-5544564-fyfdfdsd
....
//convert into array
$lines = file('myfile.txt');
//count number of lines
$numbers=count($lines);
//show every line in a row of table :
foreach ($lines as $line) {
$line=explode("-", $line);
echo "<tr>";
echo "<td>$line[0]</td>";
echo "<td>$line[1]</td>";
echo "<td>$line[2]</td>";
echo "</tr>";
}
我想用 PHP 分页来查看这个 table ,例如在一页中显示每 10 行文本文件,第 1 页中的第 1 到 10 行,第 11 到 20 行在第 2 页等...我该怎么做?
谢谢
您可以使用 array_chunk
(documentation);
array Chunks an array into arrays with size elements. The last
chunk may contain less than size elements.
然后您更改代码:
$pages = array_chunk($lines, 10); // create chunk of 10 fr each page
foreach($pages as $i => $page) {
echo "This is page num $i" . PHP_EOL;
foreach ($page as $line) { // for each line in page
$line=explode("-", $line);
echo "<tr><td>$line[0]</td><td>$line[1]</td><td>$line[2]</td></tr>";
}
}

如果您只想加载特定页面的数据,请执行以下操作:
$pageNum = _Session["page"]; // of whatever way you use to get page num - you may want to do -1 as array index starting from 0 - up to you
$pages = array_chunk(file('myfile.txt'), 10);
foreach ($pages[$pageNum] as $line) { // for each line in page you want
$line=explode("-", $line);
echo "<tr><td>$line[0]</td><td>$line[1]</td><td>$line[2]</td></tr>";
