使用php从输入框中获取值

I was wondering if it would be possible to have a php file grab data from a html page with an input box, so that the user enters a word, and the php runs using that word in the script once the user hits enter. Any help would be appreciated.

我想知道是否有可能让php文件从带有输入框的html页面中获取数据, 这样用户输入一个单词,一旦用户点击进入,php就会在脚本中使用该单词运行。 任何帮助将不胜感激。

    Use a form with the method attribute set to ‘get’ or ‘post’ like this:

    <form method=“post”>
        <input type=“text” name=“test” value=“test” />
        <button type=“submit”>submit</button>
    </form>
    

    Then on the same php page, use this to get the result, store it in a variable and output it:

    <?php
    
        $result = $_POST[‘test’];
        echo $result;
    
    ?>
