Get value from array using key

Question

I have an array like this:

Array
(
[0] => Array
    (
        [settingID] => 1
        [name] => audioCueDistance
        [setValue] => false
    )

[1] => Array
    (
        [settingID] => 2
        [name] => audioCueDistanceToGo
        [setValue] => true
    )

[2] => Array
    (
        [settingID] => 3
        [name] => audioCues
        [setValue] => true
    )

[3] => Array
    (
        [settingID] => 4
        [name] => audioCueStyle
        [setValue] => default
    )

[4] => Array
    (
        [settingID] => 5
        [name] => audioCueTime
        [setValue] => true
    )

[5] => Array
    (
        [settingID] => 6
        [name] => isMetric
        [setValue] => true
    )

How can I get individual values from key for example, I would like to output the setValue of isMetric.

Thanks

foreach ($foo as $bar) {
    if ($bar['name'] == "isMetric") {
        // Use setValue here
    }
}

Please use this solution with care. If you need to access the property often it makes sense to convert the array first so you can access the key anytime without loosing performance.

@androidavid What you said is valid but I just went with a simple loop because if someone needs to access a specific element outside of when looping against the whole collection often then it should probably just be a class in the first place instead of making an array to act as an object

From what I understand you want to do something like $myArray['isMetric']['setValue'].

As your array is not in that form you need to map it that way.

$myArray = array(
    array(
        'settingID'=>6,
        'name'=>'isMetric',
        'value'=>true
    )   
);

$myAssocArray = array_reduce($myArray, function($carry, $item){
    $carry[$item['name']] = $item;
    return $carry;
}, array());

echo $myAssocArray['isMetric']['setValue'];

foreach($array as $element)
{
    if($element['name'] = 'isMetric')
        return $element['setValue'];
}
throw new \Exception('isMetric Not Found.');
