CsvFile

The CsvFile class makes it easy to iterate through CSV files of any size. It implements Iterator and SeekableIterator so you can easily loop through the CSV using foreach:

Usage

Let's say you have a file called foo.csv with the following content:

id,name,description
0,foo,"This is a Foo"
1,bar,"This is a Bar"
2,baz,"This is a Baz"
3,qux,"This is a Qux"

You can iterate through it like this:

$csvFile = new CsvFile('foo.csv');

foreach ($csvFile as $row) {
	$id          = $row['id'];
	$name        = $row['name'];
	$description = $row['description'];
}

No header row

If your CSV doesn't have a header row:

0,foo,"This is a Foo"
1,bar,"This is a Bar"
2,baz,"This is a Baz"
3,qux,"This is a Qux"

Use the $headerRow argument to omit it:

$csvFile = new CsvFile('foo.csv', CsvFile::HEADER_ROW_NONE);

foreach ($csvFile as $row) {
	list($id, $name, $description) = $row;
}

Other formats

Other formats, like PSV or TSV are also supported:

id|name|description
0|foo|"This is a Foo"
1|bar|"This is a Bar"
2|baz|"This is a Baz"
3|qux|"This is a Qux"

$csvFile = new CsvFile('foo.csv', 0, '|');
