How to extract data from CSV file in PHP?

You can use fgetcsv to parse a CSV file without having to worry about parsing it yourself.

An example:

$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
    echo "<p> $num fields in line $row: <br /></p>\n";
    $row++;
    for ($c=0; $c < $num; $c++) {
      echo $data[$c] . "<br />\n";
    }
  }
  fclose($handle);
}
