+ParseCSV 1.3.2
+-----------------------------------
+Date: 07-Nov-2021
+
+Bugfix:
+- Allow _guess_delimiter to work with a single
+  row of data. As a consequence, `$csv->auto()`
+  now works for files with just one row of data.
+  See issue #206.
+
+-----------------------------------
+
+
+ParseCSV 1.3.1
+-----------------------------------
+Date: 20-Jun-2021
+
+Bugfix:
+- `parseFile()` will now set `$csv->data`.
+  Until now, the parsed data was only returned.
+  This adds consistency with `$csv->parse()`
+  for the following operations on the object.
+
+-----------------------------------
+
+
+ParseCSV 1.3.0
+-----------------------------------
+Date: 14-Apr-2021
+
+Breaking changes:
+- Passing file paths to parse() or new Csv() is now deprecated
+  and will be removed in v2.0.0. Use ->parseFile() instead.
+
+  WARNING: It will call trigger_error() for now.
+  This may still break your application, depending on your
+  php.ini config. You can add E_USER_DEPRECATED to the
+  error_reporting mask to avoid breaking your application:
+
+  Example:
+
+  error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_USER_DEPRECATED
+
+  This change is to avoid security issues: see issue #198.
+
+Non-breaking deprecations:
+- The function load_data() is deprecated.
+  Call loadFile() or loadDataString() instead.
+- Supplying CSV data (file content) to auto() is deprecated.
+  Please use autoDetectionForDataString().
+
+  The motivation is to make subtle gotchas less likely: when the
+  file cannot be found or read by PHP (permissions), its file path
+  would be treated like CSV data.
+- Currently, there is code to parse .php: <?...?> tags are removed
+  before the remaining file content is treated like a .csv file.
+  This rarely-used functionality will be removed in v2.0.0.
+  You are only affected if you use ParseCsv to parse .php files.

+ParseCSV 1.2.1
+-----------------------------------
+Date: 25-Apr-2020
+
+Breaking changes: none
+New features: none
+Bug fixes: none
+
+Code quality:
+- Switched from PHPUnit 4 to 6 to get rid of
+  wrappers. This will reduce friction for PhpStorm users,
+  because it gets rid of the "Multiple definitions" error
+  See issue #188. Thanks to @SharkMachine for the hint.
+-----------------------------------
+
+
+ParseCSV 1.2.0
+-----------------------------------
+Date: 07-Jan-2020
+
+Breaking changes: none
+
+New features:
+- Compatible with PHP 7.4. Thanks to @andreybolonin
+  @morrislaptop @martijnengler and @fjf2002.
+- unparse() now also understands $use_mb_convert_encoding.
+- Verbal condition operators are now allowed to contain
+  upper case letters, for example:
+  $csv->conditions = 'rating IS GREATER THAN 4';
+
+Bug fixes:
+-  All filter condition operators containing "is" or "equals"
+   were broken.
+
+Code quality:
+- Improved test coverage.
+-----------------------------------
+
+
+ParseCSV 1.1.1
+-----------------------------------
+Date: 2-Feb-2019
+
+Breaking changes: none
+
+New features: none
+
+Bug fixes:
+- Function load_data: check length of input, prevents E_NOTICE
+  if too long.
+- Fixed bugs in unparse().
+
+Code quality:
+- Improved test coverage.
+-----------------------------------
+
+
+ParseCSV 1.1.0
+-----------------------------------
+Date: 9-Aug-2018
+
+Breaking changes:
+- Ignore entirely empty lines at the end of files
+  See https://github.com/parsecsv/parsecsv-for-php/pull/142
+- Dropped support for PHP 5.4. Now, you need at leas PHP 5.5.
+- Fixed parse()'s return value: return true only if $data is useful.
+
+New features:
+- Added support for Laravel-style collections via the
+  new getCollection() function - see
+  https://github.com/parsecsv/parsecsv-for-php/pull/134
+- New function getTotalDataRowCount() - useful if
+  $limit is set - see pull request #122.
+- Added requires to keep Composer-free environments working.
+
+Bug fixes:
+- Better support for streams.
+  See https://github.com/parsecsv/parsecsv-for-php/pull/147
+- Fixed output() with custom header.
+  See https://github.com/parsecsv/parsecsv-for-php/issues/132
+- Fixed bug on _validate_fields_for_unparse() if titles property
+  is used instead of fields parameter for changing the titles for
+  unparsing.
+- Fixed bug in unparse() that caused incorrect column order
+  (Issue #41).
+
+
+Code quality:
+- Improved test coverage.
+-----------------------------------
+
+
+ParseCSV 1.0.0
+-----------------------------------
+Date: 3-March-2018
+
+- Renamed class from parseCSV to Csv and added name-
+  space "ParseCsv" for PSR compliance.
+
+- Added support for MS Excel's "sep=" to detect the
+  delimiter (Issue #60).
+
+- Added data type detection - function getDatatypes()
+  guesses the type of each column.
+
+- MIME: output() sends correct MIME type to browser
+  if the separator is a tab char (Issue #79).
+
+- Added support for mb_convert_encoding() instead of
+  iconv() - see issue #109.
+
+- A number of minor bug fixes - see GitHub issues.
+
+- Added many more unit tests.
+
+-----------------------------------
+
+
+parseCSV 0.4.3 beta
+-----------------------------------
+Date: 1-July-2008
+
+- Issue #4. Added an option for setting sorting
+  type behavior when sorting data.
+  Simply set $csv->sort_type to "regular", "numeric",
+  or "string".
+
+- Issue #6. Raw loaded file data is now cleared from
+  file_data property when it has been successfully
+  parsed to keep parseCSV's memory footprint to a
+  minimum. Specifically handy when using multiple
+  instances of parseCSV to process large files.
+
+-----------------------------------
+
+
+parseCSV 0.4.2 beta
+-----------------------------------
+Date: 31-May-2008
+
+- IMPORTANT! If you're using the output(),
+  method please note that the first parameter
+  has been completely removed as it was
+  technically just useless. Instead, the second
+  parameter (filename) doubles as its replacement.
+  Simply put, if filename is not set or null, the
+  output() method will not output a downloadable
+  file. Please update your existing code
+  when using 0.4.2 and later :)
+
+- Small fix to the headers sent by the output()
+  method.
+
+- Added a download example using the output()
+  method to the examples folder.
+
+-----------------------------------
+
+
+parseCSV 0.4.1 beta
+-----------------------------------
+Date: 29-May-2008
+
+- Fixed a small bug in how the output() method
+  handles input data.
+
+-----------------------------------
+
+
+parseCSV 0.4 beta
+-----------------------------------
+Date: 11-Apr-2008
+
+- Error reporting for files/data which is corrupt
+  or has formatting errors like using double
+  quotes in a field without enclosing quotes. Or
+  not escaping double quotes with a second one.
+
+- parse() method does not require input anymore
+  if the "$object->file" property has been set.
+
+I'm calling this a beta release due to the heavy
+modifications to the core parsing logic required
+for error reporting to work. I have tested the
+new code quite extensively, I'm fairly confident
+that it still parses exactly as it always has.
+
+The second reason I'm calling it a beta release
+is cause I'm sure the error reporting code will
+need more refinements and tweaks to detect more
+types of errors, as it's only picking two types
+or syntax errors right now. However, it seems
+these two are the most common errors that you
+would be likely to come across.
+
+-----------------------------------
+
+
+parseCSV 0.3.2
+-----------------------------------
+Date: 1-Apr-2008
+
+This is primarily a bug-fix release for a critical
+bug which was brought to my attention.
+
+- Fixed a critical bug in conditions parsing which
+  would generate corrupt matching patterns causing
+  the condition(s) to not work at all in some
+  situations.
+
+- Fixed a small code error which would cause PHP to
+  generate a invalid offset notice when zero length
+  values were fed into the unparse() method to
+  generate CSV data from an array.
+
+Notice: If you have been using the "parsecsv-stable"
+branch as an external in any of your projects,
+please use the "stable/parsecsv" branch from this
+point on as I will eventually remove the former due
+to it's stupid naming.
+
+-----------------------------------
+
+
+parseCSV 0.3.1
+-----------------------------------
+Date: 1-Sep-2007
+
+- Small change to default output settings to
+  conform with RFC 4180 (http://rfc.net/rfc4180.html).
+  Only the LF (line feed) character was used
+  by default to separate rows, rather than
+  CRLF (carriage return & line feed).
+
+-----------------------------------
+
+
+parseCSV 0.3.0
+-----------------------------------
+Date: 9-Aug-2007
+
+- Changed to the MIT license.
+
+- Added offset and limit options.
+
+- Added SQL-like conditions for quickly
+  filtering out entries. Documentation on the
+  condition syntax is forthcoming.
+
+- Small parsing modification to comply
+  with some recent changes to the specifications
+  outlined on Wikipedia's Comma-separated values
+  article.
+
+- Minor changes and optimizations, and a few
+  spelling corrections. Oops :)
+
+- Included more complex code examples in the
+  parseCSV download.

+# ParseCsv
+[![Financial Contributors on Open Collective](https://opencollective.com/parsecsv/all/badge.svg?label=financial+contributors)](https://opencollective.com/parsecsv)
+
+ParseCsv is an easy-to-use PHP class that reads and writes CSV data properly. It
+fully conforms to the specifications outlined on the 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.
+
+[csv]: http://en.wikipedia.org/wiki/Comma-separated_values
+
+## 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 7.2 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
+$csv->data[4] = array('firstname' => 'John', 'lastname' => 'Doe', 'email' => 'john@doe.com');
+$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
+````
+
+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
+````
