am using following function to state friend function between two user but i get following error
Warning: in_array() expects parameter 2 to be array, string given in C:\Users\sanoj\Documents\NetBeansProjects\PDO friends 2\userData.php on line 60
line 60 is this if (in_array($friend, $f)) { and function is bellow
function isFriend($user, $friend) {
$isFriend = false;
$friends = getUsersFriends($user);
foreach ($friends as $f) {
if (in_array($friend, $f)) {
$isFriend = true;
}
}
return $isFriend;
}
Just like the comments above, if $friends is indeed just a flat array, just use in_array alone. No need for foreach. What happens is, you're applying in_array of each string which doesn't make sense. You apply in_array to the whole array of strings:
function isFriend($user, $friend) {
return in_array($friend, getUsersFriends($user));
}
Take note that Sanoj != sanoj. It might be better to change all the caps of the collection of friends to compare against the strtolowered $friend:
Idea:
function isFriend($user, $friend) {
return in_array(strtolower($friend), array_map('strtolower', getUsersFriends($user)));
}
