get values from multidimensional array with objects

Question

I've used a little script for importing mt940 files (file of dutch bank transactions).

This is the array I get back but I need a little bit help to get the right values out of the array.

Array (
    [0] => Statement_banking Object (
        [_bank:Statement_banking:private] => ING
        [_account:Statement_banking:private] => 111111111
        [_transactions:Statement_banking:private] => Array (
            [0] => Transaction_banking Object (
                [account:Transaction_banking:private] => 111111111
                [accountName:Transaction_banking:private] => V. DE JONG KERKSTRAAT 1154 1234 BW
                [price:Transaction_banking:private] => 0.56
                [debitcredit:Transaction_banking:private] => C

            )
            [1] => Transaction_banking Object (

            )
            [2] => Transaction_banking Object (
                [account:Transaction_banking:private] =>

                [transactionCode:Transaction_banking:private] => 029 ) )
                [_startPrice:Statement_banking:private] => 44 
                [_endPrice:Statement_banking:private] => 9945 
                [_timestamp:Statement_banking:private] => 1279749600 
                [_number:Statement_banking:private] => 100
            )
        )

This key for example gives me the name and the address:

[accountName:Transaction_banking:private] => V. DE JONG KERKSTRAAT 1154 1234 BW

This key gives me the transaction price:

[price:Transaction_banking:private] => 0.56

Any suggestions?

Answer 1

Normally you would access the address and transaction price as:

foreach( $yourArray[0]->_transactions as $transaction ) {
    $foo = $transaction->accountName;
    $bar = $transaction->price;
}

But in this particular case, some of your fields are private, meaning that you can't access their value directly. You could try defining your own Statement_banking and Transaction_banking classes and define accessor methods for those fields, such as:

public class Statement_banking {
    public function getTransactions() {
        return $this->_transactions;
    }
}

public class Transaction_banking {
    public function getAccountName() {
        return $this->accountName;
    }

    public function getPrice() {
        return $this->price;
    }
}

Then your loop code becomes this:

foreach( $yourArray[0]->getTransactions() as $transaction ) {
    $foo = $transaction->getAccountName();
    $bar = $transaction->getPrice();
}

If you want to iterate over the outer array as well, you can expand it to:

foreach( $yourArray as $statement ) {
    foreach( $statement->getTransactions() as $transaction ) {
        $foo = $transaction->getAccountName();
        $bar = $transaction->getPrice();
    }
}
