Question

I’m using FedEx’s API to find “dropoff” locations for their stores that I then will be displaying using a map API (Google).

The API is working however I am having trouble as I am unfamiliar with the Object Oriented array.

I’d like to store values in the array as unique variables so I can pass them to my map API.

I’m trying to accomplish something LIKE the below:

<?php

// MY "IDEAL" solution - any other ideas welcome
// (yes, reading up on Object Oriented PHP is on the to-do list...)

$response = $client ->fedExLocator($request);

if ($response -> HighestSeverity != 'FAILURE' && $response -> HighestSeverity != 'ERROR')
{
    $response -> BusinessAddress -> StreetLines[0] = $location_0;
    $response -> BusinessAddress -> StreetLines[1] = $location_1;
    $response -> BusinessAddress -> StreetLines[2] = $location_2;
}

?>

Working FedEx Code Sample:

<?php

$response = $client ->fedExLocator($request);

if ($response -> HighestSeverity != 'FAILURE' && $response -> HighestSeverity != 'ERROR')
{
    echo 'Dropoff Locations<br>';
    echo '<table border="1"><tr><td>Streetline</td><td>City</td><td>State</td><td>Postal Code</td><td>Distance</td></tr>';
    foreach ($response -> DropoffLocations as $location)
    {
        if(is_array($response -> DropoffLocations))
        {
            echo '<tr>';
            echo '<td>'.$location -> BusinessAddress -> StreetLines. '</td>';
            echo '<td>'.$location -> BusinessAddress -> PostalCode. '</td>';
            echo '</tr>';
        }
        else
        {
            echo $location . Newline;
        }
    }
    echo '</table>';
}

?>

Answer 1

OK, from what I can tell, the $response object has two members: $response->HighestSeverity, which is a string, and $response->DropoffLocations, which is an array. $response->DropoffLocations is just an array, nothing fancy about it on its face. You can refer to its entries with square brackets (e.g. $response->DropoffLocations[0] etc), or, as they have done, walk through it with foreach.

The only thing “object oriented” about the array, other than the fact that it is a member of an object, is that its entries are objects, rather than simple values.

As a result, you’re putting your indexing in the wrong place (and missing DropoffLocations altogether). Instead of, for example, this:

$response -> BusinessAddress -> StreetLines[0] = $location_0;

You should be indexing $response->DropoffLocations itself, and then pulling the member variables from each entry, like this:

$response -> DropoffLocations[0] -> BusinessAddress -> StreetLines = $location_0;

Do note @PeterGluck’s comment, though. It’s very unlikely that you want to set that value to anything.
