How to extract data from csv file in PHP

In addition to Matt's suggestion, you can also use SplFileObject to read in the file:

$file = new SplFileObject("data.csv");
$file->setFlags(SplFileObject::READ_CSV);
$file->setCsvControl(',', '"', '\\'); // this is the default anyway though
foreach ($file as $row) {
    list ($fruit, $quantity) = $row;
    // Do something with values
}

^{source: http://de.php.net/manual/en/splfileobject.setcsvcontrol.php}

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

Example from PHP Manual:

$row = 1;
if (($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);
}
