Answer 1

foreach($array['Aircraft'] as $array){
     echo $array['A'];
}

Have you tried something like this?

Answer 2

We need to see some code where you've tried to iterate through the array. You should be trying something like $data['aircraft'][0][A] to access a single item's value.

Something like this should work to loop through:

foreach ($array AS $aircraft) {
    echo $aircraft[A] . PHP_EOL;
}

// Gulfstream G100
// Cessna Citation CJ3

Hopefully enough to give you an idea.

Answer 3

Very easy way : use var_dump() or print_r() functions to dump variable in php
But, for a specific needs, you have to think with recursive approach

function loopRecursive($input) {
    foreach ($input as $key => $value ) {
        if (is_array($value)) {
            loopRecursive($value);
        }
        else {
            printf('Key: %s value: %s<br /> ',$key, $value);
        }                                  
    }
}

Answer 4

Try this:

foreach($array['Aircraft'] as $array){
    echo $array['A']." "; // Will print Gulfstream G100 Cessna Citation CJ3 
}

Hope this helps.

Peace! xD
