JSON decode, Parse JSON response and Undefined Index

Question

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!

That's interesting that `ABCDEF` gets parsed as an `int`. Is this *exactly* what you've been working with?? The *actual* outputs? What does your JSON look like? — esqew, Jul 25 '14 at 15:43
Thanks to all for noting the difference between ID and Id, that was the missing piece... needed a second set of eyes. — user3877504, Jul 25 '14 at 18:50

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;

Please add an *explanation* instead of just posting code which is extremely similar to what the OP already has. – deceze Jul 25 '14 at 15:52

this works for me:

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

output:

Array
(
    [CustomerOriginId] => 123456
)
123456

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
