Question

I've currently got a variable called $Listings, which outputs this when var_dump($Listing);:

I need to access the details:protected array and grab information from there.

So far, I've tried:

`$variable = $classAccess->{'PerchAPI'};var_dump($variable);`

which returns NULL.

Any tips on accessing this array? Thanks.

For anybody reading: This problem was resolved, with help from @JonStirling (comments).

$xreceiver_info = $Listing->getDetails();
<?php print_r($xreceiver_info['job_title']);?>

$Listing is the variable that was putting out the block of code in the OP, and I dropped the getDetails() getter into the xreceiver_listing class, as Jon suggested.
