$car_price[“Ferrari”]=‘23bn’;
$car_price[“volvo”]=‘19bn’;

echo $car_price[“BMW”];[/php]

Are you trying to get the item in the array where the value (e.g. ‘25bn’) matches what you’re looking for?

You could use a foreach:

[php]$found = false;
$car_make = ‘’;

foreach($car_price as $key => $value) {
if($key == ‘WHAT_YOU_ARE_LOOKING_FOR’) {
$found = true;
$car_make = $key;
}
}[/php]

Replace $key with $value in the IF:

[php]$car_price[“BMW”]=‘25bn’;
$car_price[“Ferrari”]=‘23bn’;
$car_price[“volvo”]=‘19bn’;

$found = false;
$car_make = ‘’;

foreach($car_price as $key => $value) {
if($value == ‘25bn’) {
$found = true;
$car_make = $key;
}
}

echo $found ? $car_make : ‘Not found!’;[/php]
