PHP getting values in multidimensional array

Question

In php how would I get the value 'error' in this array below? I did a var_dump($myArray);

I tried echo $myArray[0][0]; and $myArray[0]; but neither of these worked.

array(1) {
 [0]=>
 array(1) {
 ["error"]=>
 array(4) {
 ["message"]=>
 string(27) "Invalid OAuth access token."
 ["type"]=>
 string(14) "OAuthException"
 ["code"]=>
 int(190)
 ["fbtrace_id"]=>
 string(11) "GJb4ZZLyAll"
 }
 }
 }

What I am actually looking for is to check the value of $myArray[0][0]; If my code works that value will be "id". If it didn't work it will be "error". So I need to see if it says "id" or "error".

• gbestard: echo $myArray[0]['error']['message']
• Prafulla Kumar Sahu: Try var_dump( array_column($myArray, ''error" )); and var_dump( array_column($myArray[0], ''error" ));

As from my understanding you want to check the value of the key. So we get the keys as an array with array_keys(), with this you then can access the first key and check if it is id or error, e.g.

$keys = array_keys($myArray[0]);
if($keys[0] == "id") {
 //good
} elseif($keys[0] == "error") {
 //bad
}

In PHP you can access array elements by name. So to get the value of "error" type:

$value = $myArray[0]["error"];
