How to iterate through a CSV file using PHP

csv_reader.php

// Open the file
$file = fopen($uri,'r');
// If the first line is a header, uncomment the following..
// $header = fgetcsv($file);
// Iterate through each row of the file
while(!feof($file)) {
  // Read in the row
  // $row will be an array of values that correspond to
  // the columns in the row, example:
  // array (
  //  [0] => 'column_1_value',
  //  [1] => 'column_2_value',
  //  [n] => 'column_n_value',
  // )
  $row = fgetcsv($file);
}
// Close the file
fclose($file);
