使用php从输入框中获取值

Question

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.

Answer 1

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;

?>
