1st of all, this is my first thread in this section... I hope its the right one since I dont know if it really is an beginners problem? but I assume it is one :) here we go:
I am trying to filter a array thats full of users, kicking out entrys that dont have a matching user_id so I only work with "buddys" out of a buddylist!
im foreach'ing the buddylist array and putting it into a new array because the current buddylist array has another array inside.. I only want the user id's!
then im calling array_filter(), passing it the user table and a callback function that has to check with in_array if the current user's ID is inside of the buddylist array and then removing/keeping the entry depending on the result...
soooo... the problem now is that if I check for any user Id with in_array() it works and finds the id. but if I use it inside of the callback function of array_filter() it tells me the second argument is a wrong datatype ????
heres the working "test" code without array_filter()
Warnung: in_array() [function.in-array]: Wrong datatype for second argument in /www/htdocs/xxxxxxxxx/XXXX.php (Line 316)
I assume I am missing something... some php rule that doesnt let me use in_array() in a callback function??? I dont understand why it isnt working inside of the callback function, even tho I am using the same vars/arrays like in my test script???
this code is all inside the constructor of an object ($engine) I created. I was using $this->buddyList first but replaced it with $engine->buddyList because I got this error
Fatal error: Using $this when not in object context in /xxxxxxxx/XXXXXXX.php on line 316
I guess the whole problem has something to do with the buddylist and the way I have to call it inside the callback function of array_filter()
