CSV Reader & Writer

This is easy to use Composer package to read and write CSV files in very convenient way. The CSV Reader is actually an OO-wrapper on the fgetcsv() built-in PHP function. It adds exceptions on errors and implements Iterator interface. You can iterate CSV reader in foreach statement like array. It supports headers of columns, so you may handle with associative data arrays. Headers may be read from first line of CSV file or be set manually. Or be read from first line and then changed by some reflection function or whatever you want.

Instead of opening you also can assign already opened file handle or stream. This package contains validation of data consistency. For example, it throws an exception if some row contains less or more columns than previous one. Therefore you don't need to always check type of return values. Just use try .. catch statement and catch exceptions if necessary. The package uses strong typing for scalars came to us from PHP7.

$csv = new CsvReader(new CsvFormat([
    'delimiter' => ',',
    'enclosure' => '"',
    'escape' => '\\',
]));
$csv->open('input.csv', CsvReader::WITH_HEADERS);

foreach ($csv as $row) {
    var_dump($row);
}

$csv->close();

Write CSV

use gugglegum\CsvRw\CsvFormat;
use gugglegum\CsvRw\CsvWriter;

$headers = ['id', 'firstName', 'lastName'];

$rows = [
    [
        'id' => 1,
        'firstName' => 'John',
        'lastName' => 'Smith',
    ],
];

$csv = new CsvWriter(new CsvFormat([
   'delimiter' => ',',
   'enclosure' => '"',
   'escape' => '\\',
]));

$csv->open('output.csv', CsvWriter::WITH_HEADERS, $headers);

foreach ($rows as $row) {
    $csv->writeRow($row);
}

$csv->close();

Troubleshooting

If you have troubles with MAC's line-endings \r, you may turn on PHP option auto_detect_line_endings:

When turned on, PHP will examine the data read by fgets() and file() to see if it is using Unix, MS-Dos or Macintosh line-ending conventions.

It may be turned on from you PHP code. Just add this before reading MAC files:

ini_set('auto_detect_line_endings', true);
