Question

i have this function to get the index key of an element in $clientsObjects array.
each element in the array keeps an object of the Client class which have a getSocket() method which returns a socket resource.

i’m 100% sure the the $socket function parameter is equal to one of the Client->getSocket() which are in the array.
from some reason the code never enters the if statement…
any suggestions ?

function getClientObjectKey($socket)
{       
    global $clientsObjects;             
    while ($sock = current($clientsObjects))
    {                       
        if ($sock->getSocket() == $socket)          
            return key($clientsObjects);    
        $sock = next($clientsObjects);
    }           
}

Answer 1

you can do the same using foreach wich would give you direct access to the key and do the iteration for you, sop you don’t have to mess around with current, next and key:

foreach ($clientsObjects as $key => $sock){                       
  if ($sock->getSocket() == $socket)          
    return $key;    
} 

anyway, using key() shouldn’t be a problem in your case, so i assume there’s a difference between the objects you try to compare.
