+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 0.2.1
+-----------------------------------
+Date: 8-Aug-2007
+
+- Fixed stupid code which caused auto function
+  to not work in some situations.
+
+-----------------------------------
+
+
+parseCSV 0.2.0 beta
+-----------------------------------
+Date: 2-Jan-2007
+
+- Added auto() function to automatically detect
+  delimiter character.
+  Useful for user upload in case delimiter is
+  comma (,), tab, or semi-colon (;). Some
+  versions of MS Excel for Windows use
+  semi-colons instead of commas when saving to
+  CSV files.
+  It uses a process of elimination to eliminate
+  characters that can not be the delimiter,
+  so it should work on all CSV-structured files
+  almost no matter what the delimiter is.
+
+- Generally updated some of the core workings
+  to increase performance, and offer better
+  support for large (1MB and up) files.
+
+- Added code examples to header comment.
+
+-----------------------------------
+
+
+parseCSV 0.1.6 beta
+-----------------------------------
+Date: 22-Dec-2006
+
+- Updated output() function.
+
+-----------------------------------
+
+
+parseCSV 0.1.5 beta
+-----------------------------------
+Date: 22-Dec-2006
+
+- Added output() function for easy output to
+  browser, for downloading features for example.
+
+-----------------------------------
+
+
+parseCSV 0.1.4 beta
+-----------------------------------
+Date: 17-Dec-2006
+
+- Minor changes and fixes
+
+-----------------------------------
+
+
+parseCSV 0.1.3 beta
+-----------------------------------
+Date: 17-Dec-2006
+
+- Added GPL v2.0 license.
+
+-----------------------------------
+
+
+parseCSV 0.1.2 beta
+-----------------------------------
+Date: 17-Dec-2006
+
+- Added encoding() function for easier character
+  encoding configuration.
+
+-----------------------------------
+
+
+parseCSV 0.1.1 beta
+-----------------------------------
+Date: 24-Nov-2006
+
+- Added support for a PHP die command on first
+  line of csv files if they have a .php extension
+  to protect secure data from being displayed
+  directly to the browser.
+
+-----------------------------------
+
+
+parseCSV 0.1 beta
+-----------------------------------
+Date: 23-Nov-2006
+
+- Initial release

+# 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()`, ``fgetcvs()`` 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
+
+**General**
+
+```php
+$csv = new ParseCsv\Csv('data.csv');
+print_r($csv->data);
+```
+
+**Tab delimited, and encoding conversion**
+
+```php
+$csv = new ParseCsv\Csv();
+$csv->encoding('UTF-16', 'UTF-8');
+$csv->delimiter = "\t";
+$csv->parse('data.tsv');
+print_r($csv->data);
+```
+
+**Auto-detect delimiter character**
+
+```php
+$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;
+$csv->parse('data.csv');
+print_r($csv->data);
+```
+
+**Limit the number of returned data rows**
+```php
+$csv = new ParseCsv\Csv();
+$csv->limit = 5;
+$csv->parse('data.csv');
+print_r($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();
+$csv->load_data('data.csv');
+$count = $csv->getTotalDataRowCount();
+print_r($count);
+```
+
+**Get most common data type for each column (Requires PHP >= 5.5)**
+
+```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->parse('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->parse('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']
+$csv->parse('data.csv');
+```
+
+**Add row/entry to end of CSV file**
+
+_Only recommended when you know the exact structure of the file._
+
+```php
+$csv = new ParseCsv\Csv();
+$csv->save('data.csv', array(array('1986', 'Home', 'Nowhere', '')), true);
+```
+
+**Convert 2D array to CSV data and send headers to browser to treat output as
+a file and download it**
+
+```php
+$csv = new ParseCsv\Csv();
+$csv->output('movies.csv', $array, array('field 1', 'field 2'), ',');
+```
+
+For more complex examples, see the ``tests`` and `examples` directories.
