Objective-PHP is a port of the Objective-C (or Objective-J runtime to PHP. This adds the language features of Objective-C nestled nicely inside the syntax of Objective-C. Moka is a port of the Apple Cocoa Frameworks (or Cappuccino).

Objective-PHP Keywords

The Objective-PHP keywords start with an @ symbol. Note that this includes the Objective-C keyword #import which is @import in ObjPHP as `#’ denotes a comment in PHP.

You may notice some keywords are added to be compatible with Objective-J syntax.

The following is a list of Objective-PHP keywords (effectively this extends the PHP keyword set by this list, ie you cannot use these names in your code) including whether they are currently supported in the language:

KEYWORD : SUPPORT (Fully/ Partial/ Partial (In Development)/ No/ No (Coming Soon))
@import: Fully
@implementation: Fully
@interface: No (See ObjC vs. ObjPHP document)
@end: Fully
@public: Partial
@private: Partial
@protected: Partial
@try: No (Coming Soon)
@catch: No (Coming Soon)
@finally: Nos
@protocol: Fully
@selector: Fully
@synthesize: No (Coming Soon)
@accessors: Partial (In Development)
@synchronized: No
@defs: No
@encode: No (Coming Soon)
@php: Fully
nil: Fully
Nil: Fully
super: Fully (see note on $self)

The following is a list of Special variables`:

$_cmd
$self (Note: self (no $) is reserved in PHP)
$this (In instance methods this is replaced by a pointer to the receiver)

Implementation Details

The more awake (or caffine fueled) of you will note that @ too has a special meaning in PHP. It is the Silence operator and mutes the output of a function call (e.g. @test(); wil output nothing). This is only a problem if one wants to name a PHP method the same as one of the Objective-PHP keywords. However this is illegal anyway (you cannot name methods after keywords) so there should be not other constraints).
