Description:
------------
---
From manual page: http://www.php.net/function.define#Examples
---

<?php
define("CONSTANT", "Hello world.",false);
echo CONSTANT; // outputs "Hello world."
echo Constant; // outputs "Constant" and issues a notice.

define("GREETING", "Hello you.", true);
echo GREETING; // outputs "Hello you."
echo Greeting; // outputs "Hello you."

?>

If the case_sensitive is true, why GREETING and Greeting output the same value (Hello you)? Then I put ,false just after "Hello world.", why CONSTANT and Constant output the different values? Plus the echo Constant; does not issue a notice.

Test script:
---------------
<?php
define("CONSTANT", "Hello world.",false);
echo CONSTANT; // outputs "Hello world."
echo Constant; // outputs "Constant" and issues a notice.

define("GREETING", "Hello you.", true);
echo GREETING; // outputs "Hello you."
echo Greeting; // outputs "Hello you."

?>

If the case_sensitive is true, why GREETING and Greeting output the same value (Hello you)? Then I put ,false just after "Hello world.", why CONSTANT and Constant output the different values? Plus the echo Constant; does not issue a notice.

Expected result:
----------------
<?php
define("CONSTANT", "Hello world.",false);
echo CONSTANT; // outputs "Hello world."
echo Constant; // outputs "Hello world."

define("GREETING", "Hello you.", true);
echo GREETING; // outputs "Hello you."
echo Greeting; // outputs Greeting

?>

Actual result:
--------------
<?php
define("CONSTANT", "Hello world.",false);
echo CONSTANT; // outputs "Hello world."
echo Constant; // outputs "Constant" and NEVER issues a notice.

define("GREETING", "Hello you.", true);
echo GREETING; // outputs "Hello you."
echo Greeting; // outputs "Hello you."

?>

the flag is case insensitive, not case sensitive

scottmac... you are right. shame...
 [2011-03-22 06:39 UTC] oop at dr dot com 
This is counterintuitive. case_sensitive = true is definitely more straightforward than case_insensitive = false.

It's been this way for more than 10 years.

Also as a default, case sensitive makes more sense.
