PHP/HTML - How to retain spaces in form input names?

问题

I have a form that has an input type=text and the name attribute has spaces in it.

When the form submits (it uses post) how can the spaces be retained, currently it replaces the spaces with underscores _

回答1:

Use arrays in the input names.

<input name="data[hello world]" type="text">

Then get the data in PHP using the 'data' key:

$_POST['data']['hello world']
