CSVReader

Category:Libraries -> CSV

CSV Formatted Data Reader

This is a utility class built to support my own strategy for multilingual and translation management as explained in the LangBuilder entry.

But I’m sure you’ll find other kind of usage…

Requirements

* CI: tested on 1.6.2
* PHP: tested on 5.2.9

Updated to use the more reliable fgetcsv() native function in a php4 compatible way (not verified).

The library code

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* CSVReader Class
*
* $Id: csvreader.php 54 2009-10-21 21:01:52Z Pierre-Jean $
*
* Allows to retrieve a CSV file content as a two dimensional array.
* Optionally, the first text line may contains the column names to
* be used to retrieve fields values (default).
*
* Let's consider the following CSV formatted data:
*
*        "col1";"col2";"col3"
*         "11";"12";"13"
*         "21;"22;"2;3"
*
* It's returned as follow by the parsing operation with first line
* used to name fields:
*
*         Array(
*             [0] => Array(
*                     [col1] => 11,
*                     [col2] => 12,
*                     [col3] => 13
*             )
*             [1] => Array(
*                     [col1] => 21,
*                     [col2] => 22,
*                     [col3] => 2;3
*             )
*        )
