RE: [PHP-DEV] how-to get array[0] and array[name] to actually reference only 1 value?
Also, even though [0] and ['id'] initially contain the same value, they are not bound together in any way. You may be able to accomplish what you desire by using references. (See the manual section on references for more information. ie. $q-data[0]["id"] = $q-data[0][0]; How can I create such a reference in code? Now I'm using zend_hash_index_update and zend_hash_update for $q-data[0][0] and $q-data[0]["id"], but that doesn't create a reference. So how should I code this?

Well, I guess that hacking the php source would work. :) However, I was
just thinking that you Could do something like this:
(Note - not tested! :)
while (list ($key, $value) = mysql_fetch_array ($result, MYSQL_ASSOC)) {
$data[] = $data[$key] = $value;
}

not bound together in any way. You may be able to accomplish what you
desire by using references. (See the manual section on references for
more
information.
ie. $q-data[0]["id"] = $q-data[0][0];
After looking for references in the php-code, I found something that seems
to work ok (zend_assign_to_variable_reference):
zval *dummy, *value, **x_ptr, **y_ptr;
MAKE_STD_ZVAL(value);
ZVAL_LONG(value, 10);
ALLOC_ZVAL(dummy);
INIT_ZVAL(*dummy);
zend_hash_update(return_value-value.obj.properties, "x", sizeof("x"),
value, sizeof(zval *), (void **) x_ptr);
zend_hash_update(return_value-value.obj.properties, "y", sizeof("y"),
dummy, sizeof(zval *), (void **) y_ptr);
zend_assign_to_variable_reference(NULL, y_ptr, x_ptr, NULL ELS_CC);
This leads me to another question: how do I obtain the x_ptr (from the
example) if the zend_hash_update was done elsewhere and no ptr was passed
then???
zend_hash_update(return_value-value.obj.properties, "x", sizeof("x"),
value, sizeof(zval *), NULL);
[...]
// How do I get the x_ptr ???
zend_hash_update(return_value-value.obj.properties, "y", sizeof("y"),
dummy, sizeof(zval *), (void **) y_ptr);
zend_assign_to_variable_reference(NULL, y_ptr, x_ptr, NULL ELS_CC);
Cheerio, Marc.

I could, but since I'm writing a database abstraction module I'm wrapping
the mysql-routines (and other db's as well, but since I just started it's
only mysql for now).
Anyway, basic functionality (including the references) now works on win, so
I'll try and compile it on my Linux-box.
Cheerio, Marc.
(BTW, why a cc to the bug database?)

[PHP-DEV] how-to get array[0] and array[name] to actually reference only 1 value?
What I'm trying to do is get the following php-script to work... (the only
thing about this that doesn't work is in the fourth 'echo' line...)
$db = dbx_connect("mysql", "localhost", "username", "password"); // works
$result = dbx_query($db, "use dbname"); // works
$q = dbx_query($db, "select id from tbl"); // works
// now I have the results in a 2D array, q-data[row][col]
// where col can be either an index or a fieldname
echo $q-data[0][0]; // works, displays first returned id, say 17
echo $q-data[0]["id"]; // works, displays first returned id (17)
// now I want to change the first returned id...
$q-data[0][0] = 12345;
// what I want is that the next two lines BOTH reflect the change
echo $q-data[0][0]; // works, displays changed id (12345)
echo $q-data[0]["id"]; // doesn't work like I would like, still displays
first returned id (17)
// This is the same behaviour that you get when you use the mysql-functions
// directly, so no help there... (you can still combine these functions with
the
// mysql-functions, if needed, like
$fieldtype = mysql_field_type($q-handle, 0);
// )
$result = dbx_close($db); // works ( $result = mysql_close($db-handle);
works too, BTW )
Currently I don't think this can be done the way I would like it to work.
Can anybody contradict me on this?
Cheerio, Marc.
