I don't follow your post at all.. but if you've added [] to an input, you've turned the data into an array. To access this in the PHP, you just access it as you would before. Instead of getting a string back though, you get an array of strings. You'll need to read more about arrays in the manual if you don't understand.

Ok, you can't do that.

 

Look, if you have:

<input type="text" name="data[u]" />

Then $_GET['data']['u'] will be the value of that input.

 

An input name cannot start with a square bracket.

 

A PHP variable name cannot start with a square bracket.

 

Why do you believe you need to do this?  Describe the actual problem.

I want to do this because it would look awesome as a site url decoration..

 

 

I have my index.php set to

[i].php

and edited my apache config to read that as index and it works fine why cant i add the [ ] brackets to the input? im sure ican there has to be a way, lol

[] cannot be used in the URL without escaping/encoding it

You cannot use them in the way you want in the URL.

 

It is against the specs:

http://tools.ietf.org/html/rfc3986#section-2.2

 

The only time [ and ]'s are allowed within the URI is for IPs:

  A host identified by an Internet Protocol literal address, version 6

  [RFC3513] or later, is distinguished by enclosing the IP literal

  within square brackets ("[" and "]").  This is the only place where

  square bracket characters are allowed in the URI syntax.  In

  anticipation of future, as-yet-undefined IP literal address formats,

  an implementation may use an optional version flag to indicate such a

  format explicitly rather than rely on heuristic determination.

 

      IP-literal = "[" ( IPv6address / IPvFuture  ) "]"

 

I believe you can do this though:

foo.php?x%5Bfoo%5D=bar would allow you to get $_GET['x[foo]'];

 

But I know you wanted it all for looks, but thats a no-go on looks IMO.

Do note that it isn't PHPs fault. This is a standard set by the IETF quite a while ago and likely never allow what you're wanting.

I think you're getting a little confused by what's going on here, so even though this topic is marked "solved" I'm going to explain it again:

 

Square brackets are special characters.  They are not valid for use in:

- URLs

- Field names

- Variable Names

- File Names

 

 

It has nothing to do with PHP, it has nothing to do with form encoding, it has nothing to do with your personal project.  It has everything to do with computers in general, and the governing bodies that regulate how the internet and programming languages work.

 

Also, mod_rewrite can do all kinds of fun things to your URLs, go play with that instead.
