Re: [PHP-DEV] Extension help
ok, I have managed to add a member variable, but am having problems when i try to
retreive it using zend_find_hash
here's the code :
for the extension :
PHP_FUNCTION(create_object)
{
... other stuff
add_property_string(return_value,"foo","hello!",1);
... other stuff
}
PHP_FUNCTION(my_other_function)
{
zval **tmpString;
zval *obj;
obj = getThis();
zend_hash_find(obj-value.obj.properties,"foo",sizeof("foo"),(void**)tmpString);
convert_to_string_ex(tmpString);
zend_printf("foo = %s",tmpString);
}
that doesn't work :(
but in a php script it does :
?
$myObject = create_object();
echo $myObject-foo;
?
produces "hello!"
what am i doing wrong ?!

look at adding it to the value.obj.properties of the class (its a
HashTable).

You're almost correct, sizeof("foo") should be sizeof("foo")+1

My fault for not reading on beyond the first typo:
zend_printf("foo = %s",tmpString);
should probably be
zend_printf("foo = %s", (*tmpString)-value.str.val);
but I may be wrong on the level of indirection.
The zval cannot automagically be put in a %s and treated as a string, you
should manually extract the pointer to the actual string.
Hope this helps!
Cheerio, Marc.
(btw, you might have a look at the way the zval struct is set up in the
source code)

even though i did convert_to_string_ex(tmpString) ?

RE: [PHP-DEV] Extension help
Hi! even though i did convert_to_string_ex(tmpString) ? You should still do that, but the only thing that really does is set the zval type to IS_STRING, and the value union is set accordingly (instead of e.g. a long in value.lval, you get the value as a string in value.str.val (and the length of the string in value.str.len, excl. terminating 0). So what you have after the conversion is still a zval, but you can now safely use the value.str.val (which is of type char *, as you would expect).

BM but I may be wrong on the level of indirection. BM The zval cannot automagically be put in a %s and treated as a string, you BM should manually extract the pointer to the actual string. BM BM even though i did convert_to_string_ex(tmpString) ? The convert_to_string_ex makes tmpString to be sting zval (otherwise you better not access the str.val part at all - there could be a pile of thrash there). That doesn't make tmpString a C string, however - it's still a zval. -- Stanislav Malyshev, Zend Products Engineer [EMAIL PROTECTED] http://www.zend.com/ +972-3-6139665 ext.115 -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Well, that's the most full one that exists. Eventually, it should be extended to cover the most, but before it happnes, you have the code and the PHP-DEV... yeah, think once i get my extension finally working I may write a tutorial on creating something more advanced than running ext_skel and adding a function - eg, defining a class, using objects etc.. -- Stanislav Malyshev, Zend Products Engineer [EMAIL PROTECTED] http://www.zend.com/ +972-3-6139665 ext.115 -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- http://www.theshining.org -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
