PHP Reading STDObject

Question

I have std object returned via SOAP Client and am trying to read out all the Names / Symbols.

Code I am using is below, but I keep getting invalid argument in foreach on the second foreach statement.

Any ideas?

object(stdClass)#3 (1) {
["ListMoney"]=> object(stdClass)#4 (3)  { 
    ["Outcome"]=> string(7) "Success" 
    ["Exchange"]=> object(stdClass)#5 (1)   { 
        ["Market"]=> string(9) "CHICMERCX" 
    } 
    ["Money"]=> object(stdClass)#6 (1)  { 
        ["Currency"]=> object(stdClass)#7 (2)   { 
            ["Symbol"]=> string(1) "$" 
            ["Name"]=> string(3) "USD"
         } 
         ["Currency"]=> object(stdClass)#7 (2)  { 
            ["Symbol"]=> string(1) "#" 
            ["Name"]=> string(3) "CND"
         }          
    }
 }

Using This Code:

foreach ($result->ListMoney as $ListMoney) { foreach ($ListMoney->Money as $Money) { foreach ($Money->Currency as $Currency) { echo $Currency->Symbol; } } }

You have a few foreach loops too many, $ListMoney->Money for example already gives you the currency:

foreach ($result->ListMoney as $ListMoney)  {
foreach ($ListMoney->Money as $Money)   {
    foreach ($Money->Currency as $Currency) {
        echo $Currency->Symbol;
    }
}
}

Should be something like:

foreach ($result->ListMoney->Money as $Currency) {
    echo $Currency->Symbol;
}

If you use more inner loops, you will run into invalid arguments because for example $result->ListMoney->Outcome->Money does not exist.

Note that by using a syntax like foreach ($result->ListMoney as ... you are skipping a level in your nested object and going straight to the second level. That applies to all your foreach loops.
