in my extension, i have a class which has methods which work slightly
differently depending on whether or not they are called statically.
as an example :

   $original = new UnicodeString("HELLO WORLD","utf8");
   $lower = UnicodeString::toLowerCase($original);    /* returns a new copy
*/
   $lower1 = $original->toLowerCase();  /* original is lowercased. return a
reference */

 the latter is for efficiency. imagine chains like
       print_r($original->reverse()->toTitleCase()->split(" "));  /* no
intermediaries created  work on $original*/

while the former allows for transformations without affecting the original
string.

since the method can behave statically, it is marked as ZEND_ACC_STATIC.
however it appears that once marked as such,
getThis() always reports NULL. i've confirmed that marking it as non static
cause the object to be properly passed.

is this a WAD. if so, is it possible (at least for internal functions) for a
method to be called statically as well as in an object context ?

Yepp, I have experienced this and forced myself to add methodNameS (the S is for
static)
method to have static calls available.

Hello l0t3k,

never ever mix static and non static methods!
The only reason this is possible is for having BC for old
bullshit concepts. Apart from that use ZEND_ACC_ALLOW_STATIC
if you really want that behavior but before you do think
twice and again and then again if there is no correct way...
