PHP 显示实时 Shell Output Z4C4AD5FCA2E7A3AAF74DBB1CED00381 内

Question

I have a shell file shell.sh that echo hi every 1 second.我有一个 shell 文件 shell.sh 每 1 秒回显一次。 I would like to display the real time output of my shell script on my website in a box.我想在我的网站上的框中显示我的 shell 脚本的实时 output。

However, the problem is that, my code doesn't show the output in a box.但是，问题是，我的代码没有在框中显示 output。 And when I click on it, everything disappears and I just see a white page.当我点击它时，一切都消失了，我只看到一个白页。

The following is my php file.以下是我的 php 文件。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
    <form method="GET" action="splitter.php">
        <label for="folderPath">Folder Path:</label>
        <input type="text" id="folderPath" name="folderPath">
    <br></br>
        <fieldset id="khz">
            <p>Please Choose Khz: </p>
          <input type="radio" value="8khz" name="khz"> 8khz <br>
          <input type="radio" value="16khz" name="khz"> 16khz <br>
        </fieldset>
    <br></br>
        <fieldset id="audio-type">
            <p>Please Choose Type: </p>
          <input type="radio" value="C12" name="group2"> Channel 1 & 2 <br>
          <input type="radio" value="LR" name="group2"> Left to Right <br>
        </fieldset>
        <div class="spaceh10"></div>
        <input class = "submitButton" type="submit" value="Submit">

    <div class="spaceh10"></div>
    <div style="width:500px;height:100px;border:1px solid #000;">
    <?php
    if (isset($_GET['folderPath']) && !empty($_GET['folderPath']) && 
    isset($_GET['khz']) && isset($_GET['group2'])) {

    $folderPath = $_GET['folderPath'];
    $khz = $_GET['khz'];
    $group2 = $_GET['group2'];
    #$folderPath $khz $group2
    $command = './shell.sh';
    while (@ ob_end_flush()); // end all output buffers if any

    $proc = popen($command, 'r');
    echo '<pre>';
    while (!feof($proc)){
        echo fread($proc, 4096);
        @ flush();
    }
    echo '</pre>';
    }
    ?>
    </div>
</body>
</html>

and below is my shell script以下是我的 shell 脚本

while true
do 
    echo "Hi"
    sleep 1
done

How do I make my code run in the box?如何让我的代码在盒子中运行？ And make sure the outputs just stay in the box and doesn't overflow.并确保输出只是留在盒子里并且不会溢出。 Why doesn't my code show the output?为什么我的代码不显示 output？

I am monitoring the server address which my php file is running.我正在监视我的 php 文件正在运行的服务器地址。 And when I click submit it loads forever on a white screen and since I know it's not gonna end I stop within the browser.当我点击提交时，它会永远加载在白屏上，因为我知道它不会结束，所以我在浏览器中停下来。 and I get the following error.我收到以下错误。

./shell.sh: line 6: echo: write error: Broken pipe

How can I show my real time shell output in a box?如何在盒子中显示我的实时 shell output？ and it doesn't outflow the box border?并且它不会流出框边框？

If you are ok with using a node tool, and not pure php, checkout websocketd and this question .如果您可以使用节点工具，而不是纯粹的 php，请查看websocketd和这个问题。

PHP is not the best choice for a realtime app, because generally php apps are short lived, but what you are asking for is along the lines of a WebSocket server. PHP 不是实时应用程序的最佳选择，因为通常 php 应用程序寿命很短，但您要求的是 WebSocket 服务器。 Alternatively, you could use polling to call a php endpoint that reads from a log file, if you really want to use php.或者，如果您真的想使用 php，您可以使用轮询来调用从日志文件读取的 php 端点。

However, it is possible , just not as easy as using node (or elixir, or go, or ruby, etc.), when so many more examples for this use case exist for node.但是，当此用例存在更多示例时，它可能不像使用节点（或 elixir、或 go、或 ruby 等）那么容易。
