how to access the count? - richb201 - 08-19-2018
I have a $result being returned from a sdk call. It has this structure:
$result
>data {array} [4]
>Items
Count
ScannedCount
>@metaData
I am trying to get the Count programmatically (I can see it is 12 in the debugger)
$i=$result.data['Count'];
$i=$result->data->Count;
I have tried these plus quite a few others. How can I get $i to equal the the Count?
RE: how to access the count? - donpwinston - 08-19-2018
why not execute a print_r($result)?
if $result is an object then $i = $result->data['Count']
assuming 'Count' references an item in $data and $data is an array.
RE: how to access the count? - richb201 - 08-19-2018
$result = $dynamodb->query($params);
$iCount = $result->data['Count'];
I am getting an error:
Message: Cannot access private property Aws\Result::$data
Filename: controllers/Configure.php
RE: how to access the count? - skunkbad - 08-19-2018
Try
$data = $result->getData();
Or
$count = $result->getCount();
RE: how to access the count? - richb201 - 08-20-2018
Those two functions don't exist. I can see the count in the result. I can't seem to take a snapshot of the debug window. here is what I see
$result={Aws\result}[1]
data={array}[4]
Items{array}[12]
Count=12
Can I somehow get the size of the items array? that would do it.

@richb201,
You could also count the items array.

Yes, is there a php function which returns the count of the items (or any) array?
RE: how to access the count? - richb201 - 08-20-2018
I tried this but it fails:
$iCount=count($result->data.Items);
$iCount=0
I then tried
$iCount=count($result[data].Items);
and $iCount = 1 instead of 12
I then tried $iCount=count($result['data'].Items);
and $iCount is 1 instead of 12.
Talk about trial and error.....
RE: how to access the count? - richb201 - 08-20-2018
Trial and error works!
This worked:
$iCount=$result['Count'];
RE: how to access the count? - php_rocs - 08-20-2018
@richb201,
for items it would be...
$iCount = count($result['Items']);
P.S. Your understanding of how arrays work was the challenge in this situation. I had to work on this issue too. I use to hate working with arrays but once I got the hang of it (more practice) I started to love working with arrays. I'm glad you figured it out.
