This is the code, it use a foreach to access to department and workers .

EDIT: Will correct several paste errors 

<?php

$json = '{
"boss": "Jeff",
"department": [{
    "office": "1111",
    "workers": "[{\"id_work\":\"123\",\"name\":\"mike\",\"mobile\":\"12345\"}]"
}]}';
$json_data = json_decode($json);
echo "Boss:".$json_data->boss;

echo "<br>";

foreach($json_data->deparment as $dep)
{

 echo "Office number:".$dep->office."<br>";

  foreach($dep->workers as $worker){
  echo "Worker ID: ".$worker->id_work."<br>";
  echo "Worker name : ".$worker->name."<br>";
  echo "Worker mobil: ".$worker->mobil."<br>";


}


}
?>

I cannot access to internal array when I try do a foreach() this happens :

Invalid argument supplied for foreach()

How I can access to the information of the nested array

    Your JSON string looks wrong, I think you need to add a ] at the end -> }]}. Commented Feb 15, 2018 at 4:22

    @Dalton just, no. There's a specific argument you can pass to json_decode() to force an array result and it does not look like OP requires it Commented Feb 15, 2018 at 4:25
  • I don't have some error pasting the json code here,but the json code is correct. But the only error this foreach($dep->workers as $worker) Commented Feb 15, 2018 at 4:26
  • Your workers property is a string, not an array. Looks like you've double-encoded it. Try foreach(json_decode($dep->workers) as $worker) or you know, fix your data format Commented Feb 15, 2018 at 4:26
  • @Landa you can use true as the second parameter in json_decode() to convert your json to normal php array. easy to handle (for me both are easy to handle) Commented Feb 15, 2018 at 4:33

The json data inside $json is wrong. The decode didn't gave errors but the array you get back is not how you want it to be, that's why you get errors after json_decode.

The error you got was because the worker value is in string format. You should update that:

From: "workers": "[{\"id_work\":\"123\",\"name\":\"mike\",\"mobile\":\"12345\"}]"

To: "workers": [{ "id_work": "123", "name": "mike", "mobile":"12345"}]

End result:

$json = '{
"boss": "Jeff",
"department": [{
    "office": "1111",
    "workers": [{ "id_work": "123", "name": "mike", "mobile":"12345"}]
}]}';

$json_data = json_decode($json);
echo "Boss:".$json_data->boss;
echo "<br>";

foreach($json_data->department as $dep)
{
    echo "Office number:".$dep->office."<br>";

    foreach($dep->workers as $worker){
        echo "Worker ID: ".$worker->id_work."<br>";
        echo "Worker name : ".$worker->name."<br>";
        echo "Worker mobil: ".$worker->mobile."<br>";
    }
}
