已成功获取JSON PHP数据，但我无法访问它

Question

I am using PHP to make a HTTP request to another web server to retrieve JSON data, the request seems to work and I am able to use var_dump to see the data but I am unsure I can access the data.

This is my code for obtaining the data:

$response = Requests::get($mydetails);

$array1 = json_decode(json_encode($response), true);

Nearly all of the things I have tried (such as echo $array1->operation->result->status) give me the same error message:

PHP Notice:  Trying to get property of non-object

This is the first few lines of the var_dump output:

 array(9) {
  ["body"]=>
  string(7017) "{"operation":{"result":{"status":"Success","message":"Request details listed successfully"},"details":[{"fields":[{"name":"requesttype","value":"Incident","type":"Pick List","displayvalue":"Request Type","allowedvalues":["Incident","Request for Change","Request For Information","Request for Work"],"mandatory":"false"},{"name":"impact","value":"Affects User","type":"Pick List","displayvalue":"Impact","allowedvalues":["Affects Business","Affects Department","Affects Group","Affects User"],"mandatory":"false"},{"name":"status","value":"Closed","type":"Pick List","displayvalue":"Status","allowedvalues":["Awaiting Customer","Awaiting Third Party","Closed","More Information Required","Open","Resolved"],"mandatory":"false"},{"name":"impactdetails","value":"-","type":"Multi Line","displayvalue":"Impact Details","allowedvalues":[""],"mandatory":"false"},{"name":"mode","value":"Phone Call","type":"Pick List","displayvalue":"Mode","allowedvalues":["Customer Portal","E-Mail","Fax","On-Site Request","Phone Call"],"mandatory":"false"},{"name":"priority","value":"Severity 2","type":"Pick List","displayvalue":"Priority","allowedvalues":["National Level 1","National Level 2","Request for Change","Severity 1","Severity 2","Severity 3","Severity 4"],"mandatory":"false"},{"name":"department","value":"General Practice","type":"Not Editable","displayvalue":"Department","allowedvalues":[""],"mandatory":"true"},{"name":"requesteremail","value":"","type":"Not Editable","displayvalue":"E-mail","allowedvalues":[""],"mandatory":"false"},{"name":"requestercontactnumber","value":"","type":"Not Editable","displayvalue"

Answer 1

The structure after the decoding is an array, so you should access it with array operators like $array1['body']['operation']['result']['status'], not with -> - which is object traversing operator. You could also decode it as an object:

$response = Requests::get($mydetails);

$array1 = json_decode(json_encode($response));

But your response seems to already be an array, so just access it, without re-encoding, maybe?

edit: After doing some assumptions about your code, you should maybe do this:

$response = Requests::get($mydetails);

$array1 = json_decode($response['body'], true);
var_dump($array1); // looks ok?
