Question

如何使用php在textarea中保存换行符？目前我有这个临时解决方案，通过使用exec执行shell字符串来完成工作，但如果可能的话，我希望它全部都在php中。这是我的临时脚本，请告诉我应该如何编辑

<?php

include 'theme.php';
/* ceklogin(); */
css();
if ($_POST['wget-send']) {
    $formdir = $_POST['dir'];
    $formlink = $_POST['link'];
    $filelink = fopen('/root/wget/wget-download-link.txt', a);
    $filedir = fopen('/root/wget/wget-dir.txt', w);

    fwrite($filedir, $formdir);
    exec('echo "' . $formlink . '" >> /root/wget/wget-download-link.txt', $out);
    echo $out[2];
    exit();
}

if ($_POST['restart-download']) {

    exec('mv /root/wget/wget-download-link.txt.done /root/wget/wget-download-link.txt');
    exit();
}

echo "<form action=\"" . $PHP_SELF . "\" method=\"post\" id=\"WgetForm\">";
echo "Download directory:<br><input type=\"text\" name=\"dir\" size=\"15\" value=\"/mnt/usb/\"/>    <br>";
echo '<br>Download link:';
echo ("<textarea name=\"link\" rows=\"13\" cols=\"62\"></textarea><br>");
echo '<input type="submit" onclick="LinkAdded()" name="wget-send" value="Download" id="WgetID"/><br>';
echo '<input type="submit" onclick="DownloadRestarted()" name="restart-download" value="Restart latest download" id="RestartWget"/>';
echo "</form></div>";
echo <<<HTML
<script type="text/javascript">

function LinkAdded(){

        alert("Link has been sucessfully sent to wget, it'll be downloaded soon, check the wget log for the download progress");
}

function DownloadRestarted(){

        alert("Download restarted, check the wget log for the download progress");
}

</script>
 HTML;
 foot();
 echo '
 </div>
 </body>
 </div>
 </html>';
 ?>

如果我使用nl2br，输出文件将是这样的

satu<br />
dua<br />
tiga<br />
empat<br />
lima

我不希望那些<br />在那里。这是包含nl2br的脚本：

<?php
include 'theme.php';
/*ceklogin();*/
css();
if($_POST['wget-send'])
    {
        $formdir=$_POST['dir'];
        $formlink=$_POST['link'];
    $filelink = fopen('/root/wget/test.txt',a);
    $filedir = fopen('/root/wget/wget-dir.txt',w);

    $savelink = nl2br($formlink);
    fwrite($filedir, $formdir);
    fwrite($filelink, $savelink);

    }

if($_POST['restart-download'])
    {
    exec('mv /root/wget/wget-download-link.txt.done /root/wget/wget-download-link.txt');
    exit();
    }

echo "<form action=\"".$PHP_SELF."\" method=\"post\" id=\"WgetForm\">";
echo "Download directory:<br><input type=\"text\" name=\"dir\" size=\"15\" value=\"/mnt/usb/\"/><br>";
echo '<br>Download link:';
echo ("<textarea name=\"link\" rows=\"13\" cols=\"62\"></textarea><br>");
echo '<input type="submit" onclick="LinkAdded()" name="wget-send" value="Download" id="WgetID"/><br>';
echo '<input type="submit" onclick="DownloadRestarted()" name="restart-download" value="Restart latest download" id="RestartWget"/>';
echo "</form></div>";
echo <<<HTML
<script type="text/javascript">

function LinkAdded()
    {
            alert("Link has been sucessfully sent to wget, it'll be downloaded soon, check the wget log for the download progress");
    }
function DownloadRestarted()
    {
            alert("Download restarted, check the wget log for the download progress");
    }

</script>
HTML;
foot();
echo '
</div>
</body>
</div>
</html>';
?>

注意我希望文件test.txt的输出如下所示<{1}}部分

<br />

将textarea保存到数据库或文本文件时使用nl2br。然后你就可以在textarea中回显它：

<?php

// Input (can be saved in database or text file)

$toSave = nl2br($_POST["link"]);

// Output (from databse or text file)

echo "<textarea name=\"link\" rows=\"13\" cols=\"62\">$output</textarea><br>";

?>

使用php在textarea中保存换行符？
