Like you said in your title, fgetcsv is the way to go. It's pretty darn easy to use.
$file = fopen('myCSVFile.csv', 'r');
while (($line = fgetcsv($file)) !== FALSE) {
  //$line is an array of the csv elements
  print_r($line);
}
fclose($file);
		
			 You'll want to put more error checking in there in case fopen() fails, but this works to read a CSV file line by line and parse the line into an array.
