Bug description:Unloading Extentions OR Overriding Native Functions OR
Importing Functions
Description:
------------
I'm building a framework which has a custom gettext implementation since
the gettext extension of PHP is poorly designed for my needs and it's not
installed in all environments so relying on it reduces compatibility. The
problem however is that it's installed in some environments and since it
claims the global "_" function which is pretty much a gettext standard
alias (and other gettext functions), it's preventing me from implementing
the gettext standard. There are no possible way for me to solve this
problem nicely today because PHP does not have the ability to either:
A. Override/undeclare/rename native functions. (Okay, I can do it via APD
but that makes extension dependability even WORSE.)
B. Unloading extensions at runtime. (Most preferable... I don't want it at
all)
C. Importing functions. (My framework uses namespaces. The fact that
functions cannot be imported by the "use" keyword really spoils this
feature. Otherwise it could actually have fix this problem.)
Note that this problem assumes a context where you can't control the
environment in which you install your application in. This is a very real
scenario for a lot of people including me. This is a practical problem, not
a theoretical one.
Also note that declaring the "_" function in a namespace would be
pointless:
1. it would no longer be compatible with the gettext standard
2. it would require refactoring of all existing string wrapped code
3. it would no longer be compatible with existing string wrapped code
4. a longer name like \foo\translate_lib\_() defeats the point of having a
short function name
Another workaround is to declare a _ forwarding function in every possible
namespace, but that solution is dumb and ugly.
As a temporary workaround I might declare something like t\s() but I don't
like that solution and it doesn't solve 1, 2 and 3 above.
Test script:
---------------
/** EITHER A: */
undeclare_function("_");
/** OR B: */
unload_extension("gettext");
/** OR C: */
namespace foo;
use foo\translate_lib;
/** Test: */
// My gettext implementation.
function _($msgid) {
return translate($msgid);
}
echo _("hello");
Expected result:
----------------
bonjour
Actual result:
--------------
Fatal error: Cannot redeclare _()
