How to access an array from stdClass Object (json output) using PHP?

Question

Hello guys just need a little help here. Because I have a json data and I decode it. But I can't access it using the foreach loop. When I tried to print the array structure I got this:

Array
(
    [0] => stdClass Object
        (
            [code] => AD
            [country] => Andorra
        )

    [1] => stdClass Object
        (
            [code] => AE
            [country] => United Arab Emirates
        )

    [2] => stdClass Object
        (
            [code] => AF
            [country] => Afghanistan
        )

    [3] => stdClass Object
        (
            [code] => AG
            [country] => Antigua and Barbuda
        )

    .
    .
    .

All I want is to access the code and country

I used this loop but it display the index name and the values:

foreach($decode_country as $p){
   foreach($p as $key => $value){
      echo $key."--".$value."<br />";
   }
}

But it display:

code--AD
country--Andorra
code--AE
country--United Arab Emirates
code--AF
country--Afghanistan
code--AG
country--Antigua and Barbuda
code--AI
country--Anguilla
code--AL
country--Albania
code--AM
country--Armenia

Answer 1

Try like

foreach($decode_country as $p){
   echo "code -- ".$p->code."<br>";
   echo "country -- ".$p->country."<br>";
}

Here $p will be considered as an object and you can extract the code and country using $p->code and $p->country .Or Better : while decoding json data you need to give like

$decode_country = json_decode($data,true);

true will return the array result.Then use

foreach($decode_country as $p){
   echo "code -- ".$p['code']."<br>";
   echo "country -- ".$p['country']."<br>";
}

Answer 2

You may try this

foreach($decode_country as $p){
    echo $p->code;
    echo $p->country;
}

Here $decode_country is an array of objects and inside foreach loop, each $p is an object.

If you use json_decode($data, true); then use

echo $p['code'];

When TRUE is used, returned objects will be converted into associative arrays. Otherwise, use

echo $p->code;
