Carry values outside the if?

PHP
1

I have this if:

foreach ($new_array_adm2 as $key => $val) {

if ($val['feature code'] === 'ADM3' ) 
       {
           
           $test = "".$val['country code']." ".$val['admin1 code']." ".$val['admin2 code']."";  
           
       }

echo $test;

}

Why $test doesn’t work here?

My guess is you’re not going the level into the array that you think you are.

Try this and see if it shows what you think it should be.

foreach ($new_array_adm2 as $key => $val) {
  echo "key: " . $key . " val: " . $val . "<br>";
}

So what do you expect $test to be if the feature code is not ADM3? At the very least you need to set it to a known value within your foreach loop:

foreach ($new_array_adm2 as $key => $val) {
    $test = null;
    if ($val['feature code'] === 'ADM3' )  {
        $test = sprintf("%s %d %s", 
            $val['country code'],
            $val['admin1 code'] ,
            $val['admin2 code']);  
    }
    echo $test . "\n";
}

By the way, while spaces within keys are allowed they are a bit unusual. Might want to use country_code instead of counter code if possible.
