In PHP4 and first PHP5 betas you could ask a parent method form a object with the following syntax : parent::method(). It was possible to use parent:: or PARENT::
Use of caps is important as it make possible to better distinguish the keyword from a classname

In the last betas (tested in php-5.0.0b3 and php5-200401031230) PARENT:: in caps output an error (Fatal error:  Class 'PARENT' not found). Same error comes with SELF:: in caps (while parent:: and self:: are OK)

Reproduce code:
class foo {
 function min() { echo "parent::method OK" ; }
 function maj() { echo "PARENT::method OK" ; }
class bar extends foo {
 function min() { parent::min() ; }
 function maj() { PARENT::maj() ; }

$obj = new bar ;
$obj->min() ; // ok in PHP4 and last PHP5
echo "\n" ;
$obj->maj() ; // error on last PHP5 snaps

Expected result:
parent::method OK
PARENT::method OK

Actual result:
parent::method OK
<br />
<b>Fatal error</b>:  Class 'PARENT' not found in <b>-</b> on line <b>8</b><br />

And what is it if it's not a bug ? a feature ?!? So there will be keywords that work only in lowercase and some others (like if, echo) wont be case sensitive ? or parent and self aren't keywords ? this seems to be strange...

I do really think it's a bug. And what else would you it to be ? Actually, it is a regression bug : something what was working in older versions (<5) is no more available in the new one.

I'm ok that 'parent' is THE good way to call that functionnality. But if it was possible to make the call without case sensitivity, it should be the same in PHP5. 

What I'm sure for now is that all websites that me and my developement group are not compatible with PHP5. And I think it's a serious regression. What do you think ?
