Works great so far...thanks for this!

Thank you for this!

Legend :)

Appreciate all the kind words folks! :)

Thank you! life saver!

You deserve a medal!

A thank you from me as well! This saved me much time (and mistakes).

@jaspal747

What if I had CSV with different delimiter than comma? For example | (pipe)?

@p1xel007 please refer https://opensource.box.com/spout/docs/ for setting your custom delimiter.

use Box\Spout\Reader\Common\Creator\ReaderEntityFactory;

$reader = ReaderEntityFactory::createReaderFromFile('/path/to/file.csv');
/** All of these methods have to be called before opening the reader. */
$reader->setFieldDelimiter('|');
$reader->setFieldEnclosure('@');

The helper code I have written should work with any delimiter as it simply uses the base library to decode each row ($row->toArray()).
