访问php变量中的一些值

I have an array variable $var. When I var_dump($var), it shows the following:

array(2) {
   [0] => array(3) {
         ["name"] => string(7) "Ferrari" 
         ["speed"] => int(120)
         ["isActive"] => bool(true)
         }array(3) {
         ["name"] => string(7) "Porsche" 
         ["speed"] => int(100)
         ["isActive"] => bool(false)
         }
}

The question is: I want to access these values. For example, i want to save the speed value of Ferrari into a variable $speed.

Something like check every element of array, If "name" = Ferrari, Set $speed= corresponding int value of choosen element of array.

What is the syntax of this in PHP.

Thanks in advance.

    $speed = null;
    foreach ($var as $car) {
        if ($car['name'] == 'Ferrari') {
            $speed = $car['speed'];
        }
    }
    echo $speed;
    

    Would be more reusable if you'll extend the array $var.
