+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 tab (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
+
+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 5.4 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);
+```
+
+**Modify data in a CSV file**
+
+```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');
+$csv->save();
+```
+
+**Replace field names or set ones if missing**
+
+```php
+$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. 
+

+

+  class.

-	----------------
-	# general usage
-	$csv = new parseCSV('data.csv');
-	print_r($csv->data);
-	----------------
-	# tab delimited, and encoding conversion
-	$csv = new parseCSV();
-	$csv->encoding('UTF-16', 'UTF-8');
-	$csv->delimiter = "\t";
-	$csv->parse('data.tsv');
-	print_r($csv->data);
-	----------------
-	# auto-detect delimiter character
-	$csv = new parseCSV();
-	$csv->auto('data.csv');
-	print_r($csv->data);
-	----------------
-	# modify data in a csv file
-	$csv = new parseCSV();
-	$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();
-	----------------
-	# add row/entry to end of CSV file
-	#  - only recommended when you know the extact sctructure of the file
-	$csv = new parseCSV();
-	$csv->save('data.csv', 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
-	$csv = new parseCSV();
-	$csv->output (true, 'movies.csv', $array);
