# ParseCsv

![PHPUnit](https://github.com/parsecsv/parsecsv-for-php/actions/workflows/phpunit.yml/badge.svg)



ParseCsv is an easy-to-use PHP class that reads and writes CSV data properly. It

fully conforms to the specifications outlined on the

[Wikipedia article][CSV] (and thus RFC 4180). It has many advanced features which help make your

life easier when dealing with CSV data.



You may not need a library at all: before using ParseCsv, please make sure if PHP's own `str_getcsv()`, ``fgetcsv()`` or `fputcsv()` meets your needs.



This library was originally created in early 2007 by [jimeh](https://github.com/jimeh) due to the lack of built-in

and third-party support for handling CSV data in PHP.

## Features



* ParseCsv is a complete and fully featured CSV solution for PHP

* Supports enclosed values, enclosed commas, double quotes and new lines.

* Automatic delimiter character detection.

* Sort data by specific fields/columns.

* Easy data manipulation.

* Basic SQL-like _conditions_, _offset_ and _limit_ options for filtering

  data.

* Error detection for incorrectly formatted input. It attempts to be

  intelligent, but can not be trusted 100% due to the structure of CSV, and

  how different programs like Excel for example outputs CSV data.

* Support for character encoding conversion using PHP's

  `iconv()` and `mb_convert_encoding()` functions.

* Supports PHP 5.5 and higher.

  It certainly works with PHP 8.3 and all versions in between.



## Installation



Installation is easy using Composer. Just run the following on the

command line:

```

composer require parsecsv/php-parsecsv

```



If you don't use a framework such as Drupal, Laravel, Symfony, Yii etc.,

you may have to manually include Composer's autoloader file in your PHP

script:

```php

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

```



#### Without composer

Not recommended, but technically possible: you can also clone the

repository or extract the

[ZIP](https://github.com/parsecsv/parsecsv-for-php/archive/master.zip).

To use ParseCSV, you then have to add a `require 'parsecsv.lib.php';` line.



## Example Usage



**Parse a tab-delimited CSV file with encoding conversion**



```php

$csv = new \ParseCsv\Csv();

$csv->encoding('UTF-16', 'UTF-8');

$csv->delimiter = "\t";

$csv->parseFile('data.tsv');

print_r($csv->data);

```



**Auto-detect field delimiter character**



```php

$csv = new \ParseCsv\Csv();

$csv->auto('data.csv');

print_r($csv->data);

```



**Parse data with offset**

* ignoring the first X (e.g. two) rows

```php

$csv = new \ParseCsv\Csv();

$csv->offset = 2;

$csv->parseFile('data.csv');

print_r($csv->data);

```



**Limit the number of returned data rows**

```php

$csv = new \ParseCsv\Csv();

$csv->limit = 5;

$csv->parseFile('data.csv');

print_r($csv->data);

```



**Get total number of data rows without parsing whole data**

* Excluding heading line if present (see $csv->header property)

```php

$csv = new \ParseCsv\Csv();

$csv->loadFile('data.csv');

$count = $csv->getTotalDataRowCount();

print_r($count);

```



**Get most common data type for each column**



```php

$csv = new \ParseCsv\Csv('data.csv');

$csv->getDatatypes();

print_r($csv->data_types);

```



**Modify data in a CSV file**



Change data values:

```php

$csv = new \ParseCsv\Csv();

$csv->sort_by = 'id';

$csv->parseFile('data.csv');

# "4" is the value of the "id" column of the CSV row

$csv->data[4] = array('firstname' => 'John', 'lastname' => 'Doe', 'email' => '[email protected]');

$csv->save();

```



Enclose each data value by quotes:

```php

$csv = new \ParseCsv\Csv();

$csv->parseFile('data.csv');

$csv->enclose_all = true;

$csv->save();

```



**Replace field names or set ones if missing**



```php

$csv = new \ParseCsv\Csv();

$csv->fields = ['id', 'name', 'category'];

$csv->parseFile('data.csv');

```



**Add row/entry to end of CSV file**



_Only recommended when you know the exact structure of the file._



```php

$csv = new \ParseCsv\Csv();

$csv->save('data.csv', array(array('1986', 'Home', 'Nowhere', '')), /* append */ true);

```



**Convert 2D array to CSV data and send headers to browser to treat output as

a file and download it**



Your web app users would call this an export.



```php

$csv = new \ParseCsv\Csv();

$csv->linefeed = "\n";

$header = array('field 1', 'field 2');

$csv->output('movies.csv', $data_array, $header, ',');

```



For more complex examples, see the ``tests`` and `examples` directories.



## Test coverage



All tests are located in the `tests` directory. To execute tests, run the following commands:



````bash

composer install

composer run test

````



Note that PHP 8.2 and newer allow PHPUnit versions that deprecate `@annotations`. The GitHub actions use Rector to

convert them to `#[attributes]`.

When pushing code to GitHub, tests will be executed using GitHub Actions. The relevant configuration is in the

file `.github/workflows/ci.yml`. To run the `test` action locally, you can execute the following command:



````bash

make local-ci

````



## Security



If you discover any security related issues, please email [email protected] instead of using GitHub issues.
