ERROR: In_array() expects parameter to be array, boolean given.

Pls help me!!! I tried TO 7 DAYS!!!
PLS HELP ME!!!
I TRIE In_array, array_search... Does not works

Please put them on [php] brackets.

PHP:

if(in_array($player1,$this->red and $player2,$this->red)){

How should that work?

Omg didn't see that.
@Valeron

PHP:

if(in_array($player1,$this->red,true) && in_array($player2,$this->red,true)){

i saw "and" is right!

Yes it is right but you didn't add ,true as the 3rd argument.

PHP:

if(in_array($player1,$this->red) and in_array($player2,$this->red)){ 

Thanks.... I will try...

function isEnemy will always return false if players are in same team.

Why? In_array will find
if(in_array($player1,$this->red) and in_array($player2,$this->red)){

unbelievable

English: If Steve is in team red and player Rick is in team red then assume that they are enemies. But they are in same team.

so you mean to remove return true; and else() and put return false;

No, if Steve is in red team and Rick is in blue team:

PHP:

public function isEnemy(IPlayer $player1, IPlayer $player2){
if($this->getTeam($player1) !== $this->getTeam($player2)) return true;
return false;
}

public function getTeam(IPlayer $player){
foreach($this->red as $p){
if($p === $player) return 'red';
}
foreach($this->blue as $p){
if($p === $player) return 'blue'
}
return null;
}


Thanks to all people... I liked your posts
