Searching an array for an object's member variable - php

Question

How would something like this be possible:
I have an object called Player:
class Player
{
public $name;
public $lvl;
}
and I have an array of these players in: $array.
For example $array[4]->name = 'Bob';
I want to search $array for a player named "Bob".
Without knowing the array key, how would I search $array for a Player named "Bob" so that it returns the key #? For example it should return 4.
Would array_search() work in this case? How would it be formatted?

Answer 1

Using array_filter will return you a new array with only the matching keys.
$playerName = 'bob';
$bobs = array_filter($players, function($player) use ($playerName) {
return $player->name === $playerName;
});

Answer 2

According to php docs, array_search would indeed work:
$players = array(
'Mike',
'Chris',
'Steve',
'Bob'
);
var_dump(array_search('Bob', $players)); // Outputs 3 (0-index array)
-- Edit --
Sorry, read post to quick, didn't see you had an array of objects, you could do something like:
$playersScalar = array(
'Mike',
'Chris',
'Steve',
'Bob'
);
class Player
{
public $name;
public $lvl;
}
foreach ($playersScalar as $playerScaler) {
$playerObject = new Player;
$playerObject->name = $playerScaler;
$playerObjects[] = $playerObject;
}
function getPlayerKey(array $players, $playerName)
{
foreach ($players as $key => $player) {
if ($player->name === $playerName) {
return $key;
}
}
}
var_dump(getPlayerKey($playerObjects, 'Steve'));
