Please refer to the Plum documentation for information about Plum in general.

Currently PlumCsv contains a reader and a writer for CSV files and uses League\CSV to actually read and write CSV files.


You can use the Plum\PlumCsv\CsvReader to read data from a .csv file.

use Plum\PlumCsv\CsvReader;

$reader = new CsvReader('countries.csv');

Optionally you can also pass the delimiter and enclosure to the constructor.

$reader = new CsvReader('countries.csv`, ',', '"');

Most CSV files have a header row. Because Plum processes a CSV file row by row you need to add HeaderConverter to change the index of each read item. In addition you can use the SkipFirstFilter to skip the header row. Both HeaderConverter and SkipFirstFilter are part of the core Plum package.

use Plum\Plum\Converter\HeaderConverter;
use Plum\Plum\Filter\SkipFirstFilter;

$workflow = new Workflow();
$workflow->addConverter(new HeaderConverter());
$workflow->addFilter(new SkipFirstFilter(1));
$reader = new CsvReader('countries.csv`, ',', '"');


The Plum\PlumCsv\CsvWriter allows you to write the data into a .csv file.

use Plum\PlumCsv\CsvWriter;

$writer = new CsvWriter('foobar.csv', ',', '"');
$writer->writeItem(['value 1', 'value 2', 'value 3');

The second and third argument of __construct() are optional and by default , and " respectively. In addition the setHeader() method can be used to define the names of the columns. It has to be called before the prepare().

$writer = new CsvWriter('foobar.csv');
$writer->setHeader(['column 1', 'column 2', 'column 3']);

When you read data dynamically you probably don't want to set the header columns manually. You can call autoDetectHeader() to use the array keys of the first item written to CsvWriter as headers.

$writer = new CsvWriter('foobar.csv');
$writer->autoDetectHeader(); // Must be called before the first `writeItem()`

If you need to further configure the writer, you can inject an instance of League\Csv\Writer to Plum\PlumCsv\CsvWriter.

use Plum\PlumCsv\CsvWriter;
use League\Csv\Writer;

$csv = Writer::createFromFileObject(new SplFileObject('countries.csv', 'w'));
$writer = new CsvWriter($csv);
