$files->getAllCSV() method

Get all rows from a CSV file

This simplifies the reading of a CSV file by abstracting file-open, get-header, get-rows and file-close operations into a single method call, where all those operations are handled internally. All you have to do is call the $files->getAllCSV($filename) method once and it will return an array of arrays (one per row). This method will also skip over blank rows by default, unlike PHP’s fgetcsv() which will return a 1-column row with null value.

This method is limited by available memory, so when working with potentially large files, you should use the $files->getCSV() method instead, which reads the CSV file row-by-row rather than all at once.

Note for the method $options argument that the length, separator, enclosure and escape options all correspond to the identically named PHP fgetcsv arguments.

Example foods.csv file (first row is header):

Example of reading the foods.csv file above:

Available since version 3.0.197.

Examples

Food,Type,Color
Apple,Fruit,Red
Banana,Fruit,Yellow
Spinach,Vegetable,Green
$rows = $files->getAllCSV('/path/to/foods.csv'); 
foreach($rows as $row) {
  echo "Food: $row[Food] ";
  echo "Type: $row[Type] ";
  echo "Color: $row[Color] ";
}

Usage

// basic usage
$array = $files->getAllCSV(string $filename);

// usage with all arguments
$array = $files->getAllCSV(string $filename, array $options = []);

filenamestring

CSV filename to read from

options (optional)array
  • header (bool|array): Indicate whether CSV has header and how it should be used (default=true): True to treat first line as header and return rows as associative arrays indexed by the header values. False to indicate there is no header and/or to indicate it should return regular non-associative PHP arrays for rows. Array to use it as the header and return rows as associative arrays indexed by your values.
  • length (int): Optional. When specified, must be greater than the longest line (in characters) to be found in the CSV file (allowing for trailing line-end characters). Otherwise the line is split in chunks of length characters, unless the split would occur inside an enclosure. Omitting this parameter (or setting it to 0, or null in PHP 8.0.0 or later) the maximum line length is not limited, which is slightly slower. (default=0)
  • separator (string): The field separator/delimiter, one single-byte character only. (default=',')
  • enclosure (string): The field enclosure character, one single-byte character only. (default='"')
  • escape (string): The escape character, at most one single-byte character. An empty string ("") disables the proprietary escape mechanism. (default="\")
  • convert (bool): Convert digit-only strings to integers? (default=false)
  • blanks (bool): Allow blank rows? (default=false)
