This is a simple implementation of a CSV file reader which adds support for seeking into a file quickly. This enables us to process large CSV files in reasonable amounts of time.

Installation

Install using composer composer require sgmarketplace/csv

Usage

Simply instantiate the CsvMappedReader class and seek away

require 'vendor/autoload.php';

$csv = new \SgCsv\CsvMappedReader('demo.csv');

The FileReader implements the \SeekableIterator and \Countable PHP Interfaces so you can easily iterate via foreach. Each entry is returned as an associative array of file column headings mapped to line values.

// Print all values in file from the column with heading 'someheading'
foreach ($csv as $line) {
    echo $line['someheading']."\n";
}
