php issues returning an array from a function

Question

I'm pulling information through curl from Fedex Rate Quote Sytem. I am getting the necessary information. The curl functions correctly. The results are accurate. But, when I try to add the results to an array, it wont pass them from the function to the page. Its like the results arent being stored in the function.

foreach($result->SOAPENVBody->RateReply->RateReplyDetails as $value) {
    $number = ++$number;
    $key1 = $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType;
    $value1 = $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->RatedShipmentDetails[0]->ShipmentRateDetail->TotalNetCharge->Amount;


    $options[$key1] = $value1;
}

    return $options;

I know that the function WILL pass the array set up like this as I tested it with

$key1 = '1';
$value1 = 'Hello';

It passed that information to the page.

When I echo out the curl results through $key1 and $value1 (echo $key1 . $value1;) it displays the correct information on the page as well. IT just wont pass it through to the array.

Below I am pasting the results from the echo to show what information is being retrieved

FIRST_OVERNIGHT: 194.35
PRIORITY_OVERNIGHT: 147.83
STANDARD_OVERNIGHT: 133.77
FEDEX_2_DAY_AM: 111.54
FEDEX_2_DAY: 99.78
FEDEX_EXPRESS_SAVER: 89.71
FEDEX_GROUND: 20.92

And I'm figuring someone will want to see how I am calling the function...here it is from the main page where the function is being called.

include_once('inc/functions/fedex_rate.php');
          $fedex_options = array();
         $fedex_options = fedex_rate($totalweight);

          foreach ($fedex_options as $key => $value) {
              echo '<tr><td colspan="2"><div class="margin10">'. $key .'</div></td><td colspan="2"><div class="margin10">'. $value .'</div></td></tr>'; 
          }

I even tried just using $options as well in the foreach loop on the main page; however, that didnt work either. I finally saw an example where someone set up a new array using array details from the function and so that is where I stopped.

Below is the fedex rate quote complete function minus sensitive information

<?

function getProperty($var) {
if ($var == 'key') return 'xxxxxxxxx';
if ($var == 'password') return 'xxxxxxxxx';
if ($var == 'account') return 'xxxxxx';
if ($var == 'meter') return 'xxxxx';
}


function fedex_rate($totalweight) {
//your account details here
$key = getProperty('key');
$password = getProperty('password');;
$account_number = getProperty('account');
$meter_number = getProperty('meter');
$residential = '1'; // 1 = true, 0 = false
    if ($residential == 1) { $residential = 'true'; }
    if ($residential == 0) { $residential = 'false'; }
if($residential == 1) { $servicetype = 'GROUND_HOME_DELIVERY'; }
if ($residential == 0) { $servicetype = ''; }



$recipient_address = 'xxxxxxx';
$recipient_city = 'xxxxxx';
$recipient_state = 'xx';
$recipient_zip = 'xxxxx';
$recipient_county = 'xx';

    return $options;

} // function

I was able to get it to work by adding an empty value before and after the $result in the array...but WHY is this the case? Why cant I pass the value of the $result tag to the array by itself?

$key1 = ''. $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType .'';

    $value1 = ''. $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->RatedShipmentDetails[0]->ShipmentRateDetail->TotalNetCharge->Amount .'';

CAN ANYONE TELL ME WHY I cannot pass the $result directly to the array without any additional blank tags? This ended up being the problem, so the person who figures that out gets the accepted answer.

Try initializing $options before you start the foreach and in the foreach just add data to it. — ivanivan

I found A solution. I posted as an unaccepted answer as well as on my question. Can anyone tell me why $result cant be passed as a standalone value? That ended up being the problem to the entire thing.... — KDJ

After parsing XML, every element is SimpleXMLElement object and object can't be set as key in array.

When you concat empty string, it became string instead of Object. as you know when you try to echo an object it call __toString method (if defined).

if you like to debug this issue, try to call,

var_dump($result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType)

You can also resolve this by:

$key1 = (string)$result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType;

OR

$key1 = $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType->__toString();

which option is the better option to use?

Samiul Amin Shanto Over a year ago

In my opinion, (string) is better option

KDJ Over a year ago

thank you for the explanation. I am new to parsing XML so that helps me for future projects working with XML. This works perfectly. You rock!

The problem is that $options is not defined before in fedex_rate(). just define it as an empty array before the foreach.

 $options = array();
 foreach($result->SOAPENVBody->RateReply->RateReplyDetails as $value) {
    ....

that doesnt solve it. I've had it set and it didnt work either,. Like I said, I can set a random array results $key1 = '1'; $value1 = 'Hello'; and it returns those as the array. ITs something about setting the $result tag in the array. ITs not wanting to pass the actual $result to the array even though it does allow me to echo it

monstercode Over a year ago

is the $result->SOAPENVBody->RateReply->RateReplyDetails not null, or traversable? Maybe the foreach is not executing because of being empty.

KDJ Over a year ago

when I echo the $key1 and $value1, it returns the correct results. It has a value set in it. I've tested the results a bunch of times to double check for that. You can see the data in the original question. The key is the shipment type, the value is the price

monstercode Over a year ago

Are you passing the correct value in $totalweight in the main script to fedex_rate()? (I suspect there is code missing between the include and the function call)

KDJ Over a year ago

yes because if i wasnt then the echo wouldnt return the correct results.
