Php multi array foreach loop

Question

i would like to find the country iso code in this array:

$countryArray = array(
        'AD' => array(
        'country_name' => 'ANDORRA',
        'dial_code' => '376'
        ),
        'AE' => array(
        'country_name' => 'UNITED ARAB EMIRATES',
        'dial_code' => '971'
        ),
        'AF' => array(
        'country_name' => 'AFGHANISTAN',
        'dial_code' => '93'
        ));

my condition is:

foreach($countryArray as $row){
    if($row->dial_code == '93'){
        echo $row; //???
    }
}

in the echo statement, i would like to display AF in this example. but the result is wrong.

Answer 1

foreach($countryArray as $key => $row){ if($row['dial_code'] == 93){ echo $key; //??? } }

try this one, just use $key variable inside your foreach loop
