Can not set empty enclosure for CSV

[matejjurancic]

This is:

- [x] a bug report
- [ ] a feature request
- [x] **not** a usage question

What is the expected behavior?

When enclosure is set to empty string, no enclosure should be written to CSV.

What is the current behavior?

Empty enclosure is changed to double quotes in PhpOffice\PhpSpreadsheet\Writer\Csv::setEnclosure(). Code was recently changed from

if ($pValue == '') {
    $pValue = null;
}
$this->enclosure = $pValue;

to

$this->enclosure = $pValue ? $pValue : '"';

and now changes empty string to double quotes.

What are the steps to reproduce?

<?php

require __DIR__ . '/vendor/autoload.php';

$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Csv($spreadsheet);
$writer->setEnclosure('');

Which versions of PhpSpreadsheet and PHP are affected?

1.13.0

My apologies - it was my pull request that introduced this change. It did not break any existing tests. and I don't understand your use case. Can you please give me a testable example of how you are using this so that I can revert this behavior and add an appropriate test.

I am actually using Laravel Excel, where the CSV configuration parameters are only passed to phpspreadsheet.
Basically all I want to do is generate a CSV file without enclosures, such as this:

2020-06-03;000123;06.53;14.22
2020-06-03;000234;07.12;15.44
...

I used to achieve this using $writer->setEnclosure('');, but this now sets enclosure to " and I get such content:

"2020-06-03";"000123";"06.53";"14.22"
"2020-06-03";"000234";"07.12";"15.44"
...

CSV files that my app generates are imported in another app. That app doesn't allow enclosures so files can't be imported. I know ... 🙄

@oleibman are there any plans to merge it back any time soon?

[crnkovic]

I would love an update for plans to merge for this as well.
