get form values into array in php
提问by Gandalf StormCrow
Is it possible to get form field values into array? EX:
是否可以将表单字段值放入数组？前任：
<?php
array('one', 'two', 'three');
?>
<form method="post" action="test.php">
<input type="hidden" name="test1" value="one" />
<input type="hidden" name="test2" value="two" />
<input type="hidden" name="test3" value="three" />
<input type="submit" value="Test Me" />
</form>
So is it possible to pass all form values no matter the number of them to the array in php ?
那么是否可以将所有表单值传递给 php 中的数组，而不管它们的数量？

Yes, just name the inputs the same thing and place brackets after each one:
是的，只需将输入命名为相同的内容并在每个输入后放置括号：
<form method="post" action="test.php">
<input type="hidden" name="test[]" value="one" />
<input type="hidden" name="test[]" value="two" />
<input type="hidden" name="test[]" value="three" />
<input type="submit" value="Test Me" />
</form>
Then you can test with
然后你可以测试
<?php
print_r($_POST['test']);
?>

It already is done.
它已经完成了。
Look at the $_POSTarray.
看看$_POST数组。
If you do a print_r($_POST);you should see that it is an array.
如果你做 aprint_r($_POST);你应该看到它是一个数组。
If you just need the values and not the key, use
如果您只需要值而不是键，请使用
$values = array_values($_POST);

This is actually the way that PHP was designed to work, and one of the reasons it achieved a large market penetration early on with web programming.
这实际上是 PHP 被设计的工作方式，也是它在 Web 编程早期实现大规模市场渗透的原因之一。
When you submit a form to a PHP script, all the form data is put into superglobal arrays that are accessible at any time. So for instance, submitting the form you put in your question:
当您向 PHP 脚本提交表单时，所有表单数据都被放入可随时访问的超全局数组中。例如，提交您在问题中提交的表格：
<form method="post" action="test.php">
<input type="hidden" name="test1" value="one" />
<input type="hidden" name="test2" value="two" />
<input type="hidden" name="test3" value="three" />
<input type="submit" value="Test Me" />
</form>
would mean that inside test.php, you would have a superglobal named $_POSTthat would be prefilled as if you had created it with the form data, essentially as follows:
这意味着在 inside 中test.php，您将拥有一个名为 superglobal 的超全局变量$_POST，它会被预填充，就像您使用表单数据创建它一样，基本上如下所示：
$_POST = array('test1'=>'one','test2'=>'two','test3'=>'three');
There are superglobals for both POST and GET requests, ie. $_POST, $_GET. There is one for cookie data, $_COOKIE. There is also $_REQUEST, which contains a combination of all three.
POST 和 GET 请求都有超全局变量，即。$_POST, $_GET. 有一个用于 cookie 数据，$_COOKIE. 还有$_REQUEST，它包含所有三个的组合。
See the doc page on Superglobalsfor more info.
