README

PHP CSV Parser is a simple csv parser written in php. It can parse csv strings or files.

It utilises Laravel's Support Library to help with providing a simple and clean structure.

Installation

PHP CSV Parser is available as a composer package and can be added to your composer.json like so.

"require": {
    ...
    "jralph/phpcsvparser": "2.*"
    ...
}

Usage

Using the CSV parser is simple and can be done by directly accessing the Jralph\PHPCSVParser\ParserManager class, or either of the Parser classes (Jralph\PHPCSVParser\Parsers\StringParser or Jralph\PHPCSVParser\Parsers\FileParser).

For ease of use, there is also a facade that has been created. Jralph\PHPCSVParser\Facades\Parser. This facade can call the create method on the ParserManager object.

<?php

use Jralph\PHPCSVParser\Facades\Parser;
use Jralph\PHPCSVParser\ParserManager;
use Jralph\PHPCSVParser\Parsers\FileParser;
use Jralph\PHPCSVParser\Parsers\StringParser;

// Using the Facade (AUTO DETECTS STRING OR FILE)
$parser = Parser::create('csv string or path to file here.');

// Using the ParserManager (AUTO DETECTS STRING OR FILE)
$parser = new ParserManager;
$parser->create('csv string of path to file here.');

// Using the File Parser (NO AUTO DETECTION)
$parser = new FileParser('path/to/file/here');

// Using the String Parser (NO AUTO DETECTION)
$parser = new StringParser('"csv","string","here"');

// Once you have an instance of a parser, you can parse the csv.
// You can optionally pass in any of the paramaters below.
$csv = $parser->parse($delimiter = ',', $enclosure = '"', $escape = '\\');

// Or no paramaters at all.
$csv = $parser->parse();

// Maybe your csv does not have column headings.
$csv = $parser->withoutHeadings()->parse();

?>

Working with the CSV

Once you have parsed the CSV, you will be given a CSV object. This object contains a collection of headers (if any) and a collection of all of the csv rows.

<?php

use Jralph\PHPCSVParser\Facades\Parser;
use Jralph\PHPCSVParser\ParserManager;
use Jralph\PHPCSVParser\Parsers\FileParser;
use Jralph\PHPCSVParser\Parsers\StringParser;

$parser = Parser::create('csv string or path to file here.');

$csv = $parser->parse();

foreach ($csv->rows() as $row) {
    // Do something with the rows.
}

?>

CSV Rows

When looping through csv rows, each row is returned as an instance of the CSVRow object.

You can access data through this object in many ways.

<?php

use Jralph\PHPCSVParser\Facades\Parser;
use Jralph\PHPCSVParser\ParserManager;
use Jralph\PHPCSVParser\Parsers\FileParser;
use Jralph\PHPCSVParser\Parsers\StringParser;

$parser = Parser::create('csv string or path to file here.');

$csv = $parser->parse();

foreach ($csv->rows() as $row) {
    // We have not told the parser to process without headings, so we can access
    // each row by its heading name.
    echo $row->heading1; // As an object.
    echo $row['heading2']; // As an array.
    echo $row->getRow('heading3'); // By a method.
}

// If we do not have or know the headings, we can loop through the row attributes.
foreach ($csv->rows() as $row) {
    // Loop through the $row object.
    foreach ($row as $column) {
        echo $column;
    }

    // Get an array of all attributes.
    $attributes = $row->getAttributes();
}

?>

Arrays and JSON

The following objects contain convertors to convert the object to an array and to json.

CSV
CSVRow

<?php

use Jralph\PHPCSVParser\Facades\Parser;
use Jralph\PHPCSVParser\ParserManager;
use Jralph\PHPCSVParser\Parsers\FileParser;
use Jralph\PHPCSVParser\Parsers\StringParser;

$parser = Parser::create('csv string or path to file here.');

$csv = $parser->parse();

echo $csv->toJson(); // Echo the entire csv, headings and rows, as json.

foreach ($csv->rows() as $row) {
    echo $row->toJson(); // Echo the entire row as json.
}

?>
