PHP CSV Parser

Requirements

• PHP 5.3 (it uses some PHP 5.3 specific functions like str_getcsv(...))

WARNING

This class has not been fully tested to ensure it works as it should -- (it's a work in progress) ;-)

UPDATE

It has now been tested on small data sets...Still remains to be seen how it performs on large data sets :)

Examples

    include("../src/Emmanix2002/PhpCSVParser.php");

    use Emmanix2002\PhpCSV\PhpCSVParser;

    $csv_parser = new PhpCSVParser();
    if($csv_parser){
        var_dump(
            $csv_parser->fromPath(__DIR__.'/csv_1.csv')
                    ->parse()
                    ->to(__DIR__.'/csv_created_by_to_path.csv')
        );
    }

    include("../src/Emmanix2002/PhpCSVParser.php");
