It may be possible to override the core function - I don't actually
know. If you just define a new function with the same function it might
work OK.
The snag I see coming at you like a tonne of bricks is 'how do you call
the original function once you have overridden it.'. This like like
calling SUPER. in Java.

Yes, that could solve it. However, my question was if I can override the
core functions :) Similar that I can do Parent::myFunction() in a subclass,
I want to do that, but with core functions :)

Hi,
I want to add some functionality when calling the mysql_query():
function my_query($Query) {
//do stuff before
mysql_query($Query);
//do things after
}
// or something like:
class PeteDB {
var $conn;
function PeteDB($db, $usr, $pwd, $etc) {
$this->conn = mysql_connect($db, $usr, $pwd, $etc);
if (!is_resource($this->conn)) die('db is useless'); //
trigger_error()
}
function query($qry/*, $args*/) {
// do stuff
$r = mysql_query($qry, $this->conn);
// do more stuff
return $r;
}
}

tada!
hint: always use some kind of wrapper for things like db related functions
(because it allows for stuff like this and, for instance, makes it alot
easier to
switch dbs - because you only have to change code in one place, not counting
any db-specific
sql floating around your app)
*/
This would just be for one project where I want to record all Queries and
the result of them, creating an own logging function.
I did a lot of Google, but no article that I found that take care of this
subject.
