thinking

hiho@ll i was interested in creating threads in php (don't know for what, just for fun now ;-) ) what i want: [code] <?php   function testfunc(){         print("IT WORKS");   }   create_thread("testfunc"); ?> [/code] explanation: the above code, creates a thread, the thread runs and prints "IT WORKS" (1) the same stuff should work with objects and some parameters would be cool, to give the thread function (2) the example (1) works, that's not my problem now my problem is (2) using objects, and parameters the code i have: [CODE] /* {{{ PHP_MCLS_CREATESOCKET */ PHP_FUNCTION(create_thread) {     zval *functionname;     if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC,"z",&functionname)==FAILURE){         RETURN_FALSE;     }     switch(Z_TYPE_P(functionname)){         case IS_STRING:{                       pthread_t mclsth;                       pthread_create(&mclsth,NULL,thread_func,functionname->value.str.val);                       pthread_detach(mclsth);                       RETURN_TRUE;                       }         default: RETURN_FALSE;     }   RETURN_TRUE; } /* }}} */ void* thread_func(void *arg){     char *funcname = (char*)arg;     zval *func_name;     zval *return_value;     if(funcname == NULL){         zend_error(E_ERROR,"MCLS: Function is null");     }     MAKE_STD_ZVAL(func_name);     ZVAL_STRING(func_name, "testfunc", 1);     ZEND_SET_SYMBOL(EG(active_symbol_table), "func_name", func_name);     TSRMLS_FETCH();     if(call_user_function_ex(CG(function_table), NULL, func_name, &return_value, 0, NULL, 0,&EG(symbol_table)) != FAILURE){         return NULL;     }     zend_error(E_ERROR,"Couldn't call function %s",funcname);     return NULL; } [/CODE] this all works with my extension but since i'm a noob in programming extensions i have no idea how can i differentiate between   create_thread("myfunc");   OR   create_thread(array($object,"myfunc"));   and how can i make "forward" this to thread_func?   i think i will need something like a wrapper structure, which holds my function call data and parameters   but since i'm a zendnoob i have no idea, how the php memory management works   and that's why i'm not sure how it works to be more concrete: Q1: what is missing for my C code to accept object methods or functions? (example code would be great) Q2: what is missing for my C code to accept parameters for the threadfunction? Q3: when, how and why do i have to free some zval vars? [edit] i forgot to mention that i'm running php-5.1.4 [/edit] thx@ll
