Access some values in php variable

Question

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.

what have you tried? It's simple array and loop syntax that you're asking for. — thescientist

You use a loop for that. foreach ($yourarray as $element) then the $element varialbe is your key value array — Ibu

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

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

You just need to get the value from the array. Check isset to make sure the value exists if you want.


$speed = (isset($var[0]['speed'])) ? $var[0]['speed'] : 0;

pls try this :

$speed = 0;
if (isset($var[0]["name"]) && isset($var[0]["speed"]) && $var[0]["name"]=="Ferrari"){
    $speed = $var[0]["speed"];
}
