Walk through array in php

Question:

I would like to go through an array but I only want a single field which in this case would be "status". Let him print the word open on the screen. Please help!

This is the arrangement:

{
    "status": "Abierto",
    "last_author": "56935387022"
}

This is my code:

$ch = curl_init();

$options = array(CURLOPT_URL => 'https://api-cluster.postcenter.io/v2/ticket/5d9b5a86b2a7d10db4a05935/',
                 CURLOPT_HEADER => false,
                 CURLOPT_RETURNTRANSFER=> TRUE,
                 CURLOPT_HTTPHEADER => array(
                    'Authorization: Key 76e7e6402ed09e3def8e09eaba1d94ea46985e4b24c6a3a422b42c06aabb1f232d6e9beb814531d233abc2564393330606e68be35987470e60a746adbe9bb117',
                    "cache-control: no-cache"
                )
                );

curl_setopt_array($ch, $options);

$r=curl_exec($ch);

    if(!$r)
    {
        $mData=array( curl_error($ch) );

    } else {
        $json=json_decode($r);
        $mData=$json;
    }

    curl_close($ch);


foreach ($mData as $item) {
    echo $item;
}

Answer:

I think you have a confusion between what is a JSON object and what is a JSON array.

This is a JSON object:

{
    "status": "Abierto",
    "last_author": "56935387022"
}

It is not an arrangement. If it were an arrangement, it would start with [ and end with ] . This is an important difference that you need to understand when working with JSON responses that come from cURL or from APIs or others.

Consequently, you can read the data directly, like this: $json->status .

Let's see a test:

$r=
    '
{
    "status": "Abierto",
    "last_author": "56935387022"
}
    ';
$json=json_decode($r);
echo $json->status;

Exit:

Abierto

Let's look at an example of a JSON array (see how it starts and how it ends).

$r=
    '
    [
{
    "status": "Abierto",
    "last_author": "56935387022"
},
{
    "status": "Cerrado",
    "last_author": "56935387023"
}
    ]
    ';
$json=json_decode($r);

Here you can read inside a loop, no matter it is an array of objects:

foreach ($json as $item){
    echo $item->status.PHP_EOL;
}

Exit:

Abierto
Cerrado

Or you can access directly using the index:

echo $json[0]->status;

Exit:

Abierto
