Description:
------------
The first letter lowercase is not a constant.
Only the first capital letter should be recognized as a constant.

I am too stressed because of constants in program coding.
I hope to improve soon.


I made it in lowercase, but I get an error.	
Notice: Use of undefined constant link - assumed 'link' in /home/mall/phpmall/cc_list.php on line 83

Test script:
---------------
$arr = preg_split("/-/",$f[link]);

No, constants can be in lowercase.

You need a string for the array key. Strings use quotes.

$arr = preg_split("/-/",$f["link"]);

I know it.
I'm not saying that.
If you write an uppercase letter as the first character in a constant grammar,
You do not have to do that.
Is not that right?

I mean, do not treat lowercase letters as constants.

PHP does not care if it is uppercase or lowercase. What matters is how you use it.

It's true, most people name constants in uppercase, but that is not a requirement and PHP should not make it a requirement. Lowercase constants are allowed.

Do not you understand me?
Constant names should not be lowercase.
Exclude lowercase characters in constant names.
In the next version of PHP, allow only uppercase letters in constant names.
