循环通过关联数组的阵列

Question

I have this (I'm only showing three records, there are many, many more)

Array
(
[0] => Array
    (
        [name] => Johnson, John
        [telephonenumber] => 555.555.555
        [department] => Department A
    )

[1] => Array
    (
        [name] => Johnson, Bill
        [telephonenumber] => 555.555.4444
        [department] => Department B
    )

[2] => Array
    (
        [name] => Johnson, Carry
        [telephonenumber] => 555.555.3333
        [department] => Department C
    )
)

There will be multiple members of Department A, B, etc. and I need to loop through this data and spit out only members of Department A. I have tried:

if ($phoneList['department'] == 'Falmouth') {
    echo $phoneList['name'] . '<br>';
    echo $phoneList['telephonenumber'] . '<br>';
    echo $phoneList['department'] . '<br><br>';
}

But I am getting errors because I think $phoneList['department'] doesn't exist (shouldn't be $phoneList[0]['department'])?

Either way, that won't help... how can I search through all 90 of these arrays and only print out those with Department A status?

$phoneList is the variable being passed to my view (using codeigniter, ldap and php)

You could use foreach:

foreach($phoneList as $item)
{
  if($item['department'] == 'Falmouth')
  {
    echo $phoneList['name'] . '<br>';
    echo $phoneList['telephonenumber'] . '<br>';
    echo $phoneList['department'] . '<br><br>';
  }
}
