[英]Display entered text with echo after input PHP
I want to do something very simple. 我想做一些非常简单的事情。 After a user enters text in an HTML text box then hits submit, the PHP echo's the entered text.
用户在HTML文本框中输入文本然后点击提交,PHP回显是输入的文本。 I searched all over and I cant find out how to do it!
我搜遍了所有,我无法找到如何做到这一点! There must be some way!
必须有一些方法! I want something like this except
$foo
is what the entered text was. 我想要这样的东西,除了
$foo
是输入的文本。
<html>
<input type="text" name="something" value="$foo"/>
<html>
<?php
echo $foo = "ben";
echo "foo is $foo"; // foo is foobar
?>

<input type="text" name="something" value="<?= isset($_POST['something']) ? htmlspecialchars($_POST['something']) : '' ?>" />
<input type="submit" name="submit" />
</form>
<?php
if(isset($_POST['submit'])) {
echo 'You entered: ', htmlspecialchars($_POST['something']);
}
?>
