JSON解码，解析JSON响应和未定义索引

Trying to use some decoded json data, but I'm unable to extract it to use. I've looked at other examples that should work, but haven't worked for me.

What am I missing?

(I'm trying to do what is in the first answer of How to parse json response from CURL )

Raw JSON

{"CustomerOriginId":123456}

JSON Decode:

$result = json_decode($head, true);

Print_R results (print_r($result);):

Array ( [CustomerOriginId] => 123456 ) 

Var_Dump results (var_dump($result);):

array(1) { ["CustomerOriginId"]=> int(123456) } 

My attempts to extract the data for use:

Attempt 1

Attempt 1 Code:

$test45 = $result["CustomerOriginID"];
echo $test45;

Attempt 1 Error:

Notice: Undefined index: CustomerOriginID

Attempt 2

Attempt 2 Code:

$test46 = $result['CustomerOriginID'];
echo $test46;

Attempt 2 Result:

Notice: Undefined index: CustomerOriginID

Attempt 3

Attempt 3 Code:

$test47 = $result[0]['CustomerOriginID'];
echo $test47;

Attempt 3 Result:

Notice: Undefined offset: 0

Attempt 4

Attempt 4 Code:

$test48 = $result[1]['CustomerOriginID'];
echo $test48;

Attempt 4 Result:

Notice: Undefined offset: 1

I'm sure it's something small, but I haven't found an answer as of yet.

Cheers!

The index for your array is "CustomerOriginId", not "CustomerOriginID" (note the case).

$json  = '{"CustomerOriginId":123456}';
$array = json_decode($json, true);

print $array['CustomerOriginId'];  // outputs 123456

Undefined Index usually means you are accessing the array value the wrong way. The index must match CustomerOriginId or it will be undefined.

Try this:

$json='{ "CustomerOriginId" : 123456 }';
$result = json_decode($json, true);
$CustomerOriginId = $result['CustomerOriginId'];
echo 'CustomerOriginId = '.$CustomerOriginId;

or without associative array

$json='{ "CustomerOriginId" : 123456 }';
$result = json_decode($json);
$CustomerOriginId = $result->CustomerOriginId;
echo 'CustomerOriginId = '.$CustomerOriginId;

this works for me:

$x = json_decode('{"CustomerOriginId":123456}', true);
print_r($x); 
print $x['CustomerOriginId'];

output:

Array
(
    [CustomerOriginId] => 123456
)
123456
