  1. Hello, I have a CSV file that looks like this: "Account","State","Zip","Email","Birth Date","Favorites","Balance" with data rows in them. I need to calculate total balances aggregated by state, need to get output in .txt flle like: State, Balance value, value this is how I started : $inputfile = 'input.csv'; $inputHandle = fopen($inputfile, "r"); $output = array(); while (($data = fgetcsv($inputHandle, 1024, ",")) !== FALSE){ foreach($data as $line) { list($state, $balance) = $data; $state = trim($state); $balance = trim($balance); $output[$state] += (int)$balance; file_put_contents('summary.txt', var_export($output, TRUE)); } } I get unidentified inxex errors on $output[$state] += (int)$count; May be i make some mistake in line: list($state, $balance) = $data; Could someone maybe propose a better, more convinient solution here?
