Bug #61275 Cannot have class method with same name as language construct
Submitted: 2012-03-04 17:52 UTC Modified: 2012-03-04 18:30 UTC
From: php at mralston dot com Assigned:
Status: Duplicate Package: Class/Object related
PHP Version: 5.4.0 OS: Any
Private report: No CVE-ID: None

It isn't possible to have a class method whose name is the same as any of the 
language constructs, e.g. array(), doing so creates a parse error as follows:

PHP Parse error: parse error, expecting `T_STRING' in - on line 8

The error message is somewhat cryptic and confusing when it affects code which 
otherwise perfectly valid.

This perhaps isn't a big deal for most people as the work around is to rename your 
method. It is a problem when using a different name for the method is undesirable 
(e.g. I'm creating a framework in PHP which emulates that from a different 
programming language, so ideally the method names should be the same).

Test script:

$test=new testClass();

class testClass
	public function array()
		echo("testClass::array() called.");


Expected result:
testClass::array() called.

Actual result:
PHP Parse error: parse error, expecting `T_STRING' in - on line 8

Changed package field from 'Compile Failure' to 'Class/Object related', as 
'Compile Failure' is probably intended to relate to problems compiling PHP itself, 
rather than PHP scripts.

This is a duplicate of See there for a discussion of why this is hard to do.

Fair enough. I didn't spot that bug report, but I didn't really know what to 
search for when I was looking.

I don't quite understand from the other thread why resolving it is difficult, 
however as I am not intimately familiar with how PHP operates under the hood I 
am willing to accept that there are perfectly valid reasons beyond my 

I'll +1 the other bug report. :-)
