php扩展开发之数组初始化及赋值

PHP_FUNCTION(hello_array){
        char *mystr;
        zval *mysubarray;
        array_init(return_value); //初始化一个新数组
        add_index_long(return_value, 42, 123);//向数字索引的数组增加指定类型的值
        add_next_index_string(return_value, "I should now be found at index 43");
        add_next_index_stringl(return_value, "I'm at 44!", 10);
        mystr = estrdup("Forty Five");
        add_next_index_string(return_value, mystr);
        add_assoc_double(return_value, "pi", 3.1415926535);
}

var_dump(hello_array());
