$_POST 空格转换为下划线

$_POST spaces converted in underscores($_POST 空格转换为下划线)

问题描述

我有一个像这样的 HTML 下拉菜单

I have an HTML dropdown menu that looks like this

<select name='not working random test!'>
<option value='0'>Select quantity:</option>
<option value='1'>1 room</option>
<option value='2'>2 rooms</option>
</select>

是否有可能，如果我使用 var_dumping $_POST，我会看到类似的内容?

Is it even possible that, if I'm var_dumping $_POST, I see something like this?

["not_working_random_test!"]=>
string(1) "1"

这给我的引擎造成了一些麻烦:我希望我为选择指定的名称是相同的.为什么没有发生这种情况?

This is causing some troubles with my engine: I expect the name I specify for the select to be the same. Why is this not happening?

推荐答案

这是标准的 PHP 行为.来自文档:

This is standard PHP behaviour. From the documentation:

变量名中的点和空格被转换为下划线.例如 <input name="a.b"/> 变成 $_REQUEST["a_b"].

Dots and spaces in variable names are converted to underscores. For example <input name="a.b" /> becomes $_REQUEST["a_b"].

PHP 转换为 _(下划线)的字段名称字符的完整列表如下(不仅仅是点):

---

The full list of field-name characters that PHP converts to _ (underscore) is the following (not just dot):

• chr(32) (空格)
• chr(46) . (dot)
• chr(91) [(左方括号)
• chr(128) - chr(159)(各种)

• chr(32) (space)
• chr(46) . (dot)
• chr(91) [ (open square bracket)
• chr(128) - chr(159) (various)

如果 一个左方括号和一个右方括号都存在，它们不会被转换，但是 $_POST 元素变成了一个数组元素.

If both an open and a closing square bracket are present, they are not converted but the $_POST element becomes an array element.

<input name='hor[se'>
<input name='hor[se]'>

将变成:

$_POST['hor_se'];
$_POST['hor']['se'];
