How to get the value of a key within an nested object array PHP

Question

I've been trying to learn PHP arrays, I have got the basic but struggling with this one.

I'm looking to try and get the value of a key "pdfUrl" by calling the key I want.

Any help would be greatly appreciated.

Array ( [0] => Clearbooks_Soap_1_0_Invoice Object ( [items] => Array ( [0] => Clearbooks_Soap_1_0_Item Object ( [description] => Line Item #1 [unitPrice] => 24.99 [vat] => 5 [quantity] => 1 [type] => 1001001 [vatRate] => 0.2 ) ) [description] => API Test Invoice [entityId] => 16 [invoice_id] => 209 [invoice_prefix] => INV [invoiceNumber] => 204 [reference] => [dateCreated] => 2012-10-19 00:00:00 [dateDue] => 2012-11-16 00:00:00 [dateAccrual] => 2012-10-19 00:00:00 [creditTerms] => 30 [bankPaymentId] => 0 [project] => 0 [external_id] => [status] => approved [pdfUrl] => https://secure.clearbooks.co.uk/accounting/sales/invoice_html/?source=statement&type=invoice&c=2&auth=-lHLOCMD8mOPS5qyEjiw2g [themeId] => 0 [type] => S [vatTreatment] => [multicurrency] => 0 [gross] => 29.99 [net] => 24.99 [vat] => 5 [paid] => 0 [balance] => 29.99 [foreignCurrencyBalance] => 0 ) )

You start out with an array with only one object. To call this object you can use:

$nameVar[0]

Then we have an object. You can not use '[]' for objects in PHP. Use '->' to get the value of properties of an object:

$nameVar[0]->pdfUrl

So if we want the unitprice of the first item we use:

$nameVar[0]->items[0]->unitPrice

Absolute legend, thank you very much. Something so simple and I was over thinking it like crazy hahaha.
