输入 PHP 后显示带有回显的输入文本
我想做一些非常简单的事情.用户在 HTML 文本框中输入文本然后点击提交后，PHP 回显输入的文本.我到处搜索，我找不到怎么做！一定有什么办法！我想要这样的东西，除了 $foo 是输入的文本.
I want to do something very simple. After a user enters text in an HTML text box then hits submit, the PHP echo's the entered text. I searched all over and I cant find out how to do it! There must be some way! I want something like this except $foo is what the entered text was.
<html>
<input type="text" name="something" value="$foo"/>
<html>
<?php
echo $foo = "ben";
echo "foo is $foo"; // foo is foobar
?>
