Multidimensional array loop not displaying the result for objects

Question

I am getting the result from the SOAP client as an response. I just have to analyze the structure of the parameter and display the results accordingly. I have the following srucutre for SerialEquipment and i am getting the results peoperly for all the parameters except the Esaco parameter. The Esaco parameter is an array object and it resides inside the SerialEquipment array. I am trying to fetch the response from Esaco array object but getting an error as Invalid arguments supplied for foreach. I am not understanding how to get the results for Esaco Parameter by looping properly.Just a small mistake i am doing in looping the array.

Code:

foreach($Serial as $key => $obj)
   {
        echo "<b>"."Serial Equipment=>" . $key . "</b>"."<br>";
        echo "Code=>". $obj->Code . "<br>";
        echo "Desc Short=>". $obj->Desc_Short . "<br>";
        echo "Desc Long=>". $obj->Desc_Long . "<br>";


        foreach($obj->Esaco as $key2 => $obj2)  
        {  
            if($obj2 === null){
        // doesn't contain Esaco
        break;
            }
            else{
              echo "<b>"."Esaco=>" . $key2 . "</b>"."<br>";                 
            echo "EsacoMainGroupCode=>". $obj2->EsacoMainGroupCode . "<br>";
            echo "EsacoMainGroupDesc=>". $obj2->EsacoMainGroupDesc . "<br>";
            echo "EsacoSubGroupCode=>".  $obj2->EsacoSubGroupCode . "<br>";
            echo "EsacoSubGroupCode=>".  $obj2->EsacoSubGroupDesc . "<br>";
            echo "EsacoSubGroupCode=>".  $obj2->EsacoGroupCode . "<br>";
            echo "EsacoSubGroupCode=>".  $obj2->EsacoGroupDesc . "<br>";  
        }       
        }           
     }      

if($parameter['aktion'] == 'getVehicle') 
{   
     $vehicle = getVehicleValuation();
     $Serial=$vehicle['SerialEquipment'];        
     $VehicleFuel=$vehicle['VehicleFuel'];

        foreach($VehicleFuel as $key => $obj2)
        {           
            echo "Fuel Type=>". $obj2->Fuel_Type . "<br>";
            echo "Fuel Type Code=>". $obj2->Fuel_Type_Code . "<br>";
            echo "ECE_Unit=>". $obj2->ECE_Unit . "<br>"; 
            echo "ECE_In=>". $obj2->ECE_In . "<br>";     
            echo "ECE_Out=>". $obj2->ECE_Out . "<br>";
            echo "ECE_All=>". $obj2->ECE_All . "<br>";
            echo "ECE_CO2=>". $obj2->ECE_CO2 . "<br>";                       
        }   
}

This is my structure for SerialEquipment: enter image description here

if($parameter['aktion'] == 'getVehicle') 
{
    $vehicle = getVehicleValuation();
    if(($serials = $vehicle['SerialEquipment']) === null){
        // doesn't contain SerialEquipment
        break;
    }

    foreach($serials as $serial){
        print "Code =>" . $serial->Code . "<br>";
        print "Desc Short =>" . $serial->Desc_Short . "<br>";

        //...

        foreach($serial->Esaco as $esaco){
            print "EsacoMainGroupCode =>" . $esaco->EsacoMainGroupCode. "<br>";
            print "EsacoMainGroupDesc =>" . $esaco->EsacoMainGroupDesc. "<br>";

            //...
        }
    }
}

And for the VehicleFuel:

if($parameter['aktion'] == 'getVehicle') 
{   
 $vehicle = getVehicleValuation();
 $Serial=$vehicle['SerialEquipment'];        
 $VehicleFuel=$vehicle['VehicleFuel'];

 $fuelType = $VehicleFuel->Fuel_Type;

 // if there is only going to be one VehicleFuel object Vehicle, then just do..
 echo "Fuel Type =>". fuelType->Fuel_Type . "<br>";
 echo "Fuel Type Code =>". $fuelType->Fuel_Type_Code . "<br>";

 // if there will be more than one, you will want to use a loop...

    foreach($fuelType as $obj)
    {           
        echo "Fuel Type=>". $obj->Fuel_Type . "<br>";
        echo "Fuel Type Code=>". $obj->Fuel_Type_Code . "<br>";
        echo "ECE_Unit=>". $obj->ECE_Unit . "<br>"; 
        echo "ECE_In=>". $obj->ECE_In . "<br>";     
        echo "ECE_Out=>". $obj->ECE_Out . "<br>";
        echo "ECE_All=>". $obj->ECE_All . "<br>";
        echo "ECE_CO2=>". $obj->ECE_CO2 . "<br>";                       
    }   
}

hello Alex it will not work because u have to loop inside loop in order to get all the values for Esaco...

Alex Over a year ago

Why do you? It's just an object inside an object? There are not more than one Esaco objects in the vehicle object, so there is no need to loop?

Alex Over a year ago

@user3844830 I have updated to better reflect your specific example

user3844830 Over a year ago

yes there are multiple values stored inside Esaco object so if we dont loop it, it will only show the first values for Esaco object...

Alex Over a year ago

@user3844830 Ah I see, there ARE potentially more than one Esaco object per SerialEquipment object. I have updated my answer.

The key Esaco is an object not an array. You should change your second foreach.

foreach($Serial as $key => $obj) {       
    echo "Serial Equipment=>" . $key . "<br>";
    echo "Code=>". $obj->Code . "<br>";
    echo "Desc Short=>". $obj->Desc_Short . "<br>";
    echo "Desc Long=>". $obj->Desc_Long . "<br>";  
    foreach($obj->Esaco as $key2 => $obj2) {
        echo $obj2;
        //...
    }           
}

thanks man its running now :) but i am getting as error in this loopforeach($obj->Esaco as $objects) saying invalig arguments supplied ?

Debflav Over a year ago

After your edition. You can delete the thrid foreach.

user3844830 Over a year ago

No man when i removed third foreach its giving null values for Esaco :( Actually its showing the values only for those SerialEquipment those have only single time Esaco value. When there are multiple times Esaco values are coming its showing null there

Debflav Over a year ago

I don't know what you are waiting for in Esaco object but I guess you can do it by yourself. It's the same behavior just loop on this object.
