Re: [PHP-DEV] Working with arrays.
I did it like so:
bitbucket.org/winapiforphp/system/src/93583820bbc1/winsystem_registry.c#cl-298
It's a little messy.

Hi.
What macros exist regarding processing arrays in PHP (core not userland)?
I want to pass ...
array('value1', 'value2', 'value3')
to a function and in the function have it converted to
'value1\0value2\0value3\0\0'.
Conventionally, I'd need to iterate the array to get the lengths of
all the elements, add the number of elements to this value and then 1
more for the trailing \0.
Unless there are some macros to allow to do this sort of thing more easily.

[PHP-DEV] Re: alternative to the fopen() hack in autoloaders
Lukas Kahwe Smith wrote:
Ahoi,
I have written an RFC for a more efficient solution to get rid of the
common fopen() hack inside autoloaders:
if ($fp = @fopen($file, 'r', true)) {
fclose($fp);
include $file;
}
Here is the gist of the proposal:
In order to solve the above issues this RFC proposes the addition of a
new construct/function for now called “autoload_include” for lack of a
better name that largely behaves like the “include” does today with the
following differences, that when the include failed because of a missing
file no warning is raised and php null is returned.
Further details can be found on the wiki:
http://wiki.php.net/rfc/autoload_include
As stated in the RFC, I am not happy with the name autoload_include.
Suggestions welcome!

thank you, for your immidiatly response.
yes, i know that ,,return'' is a language construct. it is documented
that the parentheses are not required (1) but not
that it is necessary that there have to be an argument if the
parantheses are used.
using ,,echo()'' for example, which is a function(!), brings the same
parser error when using empty parentheses.
it seems like an error in the parser where functions or ,,language
constructs'' where the parantheses are optional.

Thank you for your report.
The behavior you report is not a bug. You call return as if it is a
function. It is not, it is a language construct.
The correct syntax is:
return 'bar';
or
return;
The parenthesis are not needed.

Expected result:
no parser error :-)
