Class: csv_export_writer - X-Ref
Utitily class for exporting of CSV files.| __construct($delimiter = 'comma', $enclosure = '"', $mimetype = 'application/download', $bom = false) X-Ref |
| Constructor for the csv export reader param: string $delimiter The name of the character used to seperate fields. Supported types(comma, tab, semicolon, colon, cfg) param: string $enclosure The character used for determining the enclosures. param: string $mimetype Mime type of the file that we are exporting. param: boolean $bom If true, prefix file with byte order mark. |

| download_array($filename, array &$records, $delimiter = 'comma', $enclosure='"') X-Ref |
| Creates a file for downloading an array into a deliminated format. This function is useful if you are happy with the defaults and all of your information is in one array. param: string $filename The filename of the file being created. param: array $records An array of information to be converted. param: string $delimiter The name of the delimiter. Supported types(comma, tab, semicolon, colon, cfg) param: string $enclosure How speical fields are enclosed. |
| print_array(array &$records, $delimiter = 'comma', $enclosure = '"', $return = false) X-Ref |
| This will convert an array of values into a deliminated string. Like the above function, this is for convenience. param: array $records An array of information to be converted. param: string $delimiter The name of the delimiter. Supported types(comma, tab, semicolon, colon, cfg) param: string $enclosure How speical fields are enclosed. param: bool $return If true will return a string with the csv data. return: string csv data. |
