Description:
------------
With a space between -> and Imagick::clone PHP throws a parser error. Without the space everything is perfect.

Reproduce code:
---------------
$imagick = new Imagick ( 'path/to/a/image.jpg' );
$clone = $imagick -> clone ( ); // Spaces important!
// Code which runs:
//$clone = $imagick ->clone ( );

Expected result:
----------------
Clone of $imagick in $clone.

Actual result:
--------------
Parse error:  syntax error, unexpected T_CLONE, expecting T_STRING or T_VARIABLE or '{' or '$' in .../file.php on line 2

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

Oops, misread but I can't reproduce the problem with:

class a { function foo(){echo "foo\n";}} $b = new a; $b -> foo();

Pajoye, I think that's not a problem of imagick, more a parser problem. You can't reproduce the problem because foo() is not clone(). "clone" is a reserved keyword (http://docs.php.net/clone), imagick can use this function because it's in the class namespace (http://docs.php.net/manual/en/function.imagick-clone.php). PHP supports this if the parser detects "->" before the keyword. But the parser does not recognize the space in this case.

Yes, I misread the initial report. My 2nd comment asked you to test with a snapshot.
 [2008-06-23 00:30 UTC] j dot jeising at gmail dot com
Tested with latest snapshot on windows

php test.php
Parse error: syntax error, unexpected T_CLONE, expecting T_STRING or T_VARIABLE
or '{' or '$' in test.php on line 4

Same probleme here.

Weird, it works here on windows and linux.

Can you zip your src and post a link to it here please? Maybe there is a hidden character (not a space)?

Scott, can you take a look? You may be the best person to check the parser :)
 [2008-07-01 10:15 UTC] scottmac@php.net
This is fixed in PHP 5.3 since the move to re2c, I will see whats possible for the 5.2 branch.
 [2008-07-02 14:46 UTC] j dot jeising at gmail dot com
I detect, that the bug affects all keywords with Object Operator before, example:

$this -> class = 'foobar';
 [2008-11-17 19:37 UTC] scottmac@php.net
This isn't a bug in 5.2, its just a limitation of flex.
