Spreadsheet
Replace a worksheet within an Excel workbook (.xlsx) without changing any other properties of the file.
License
This program is free software; see LICENSE for more details.
Details
The main purpose of this library is adding a "data table" to an existing excel file without modifing any other components. This is especially useful if you have a template file, e.g. for reporting including "advanced" features like charts, pivot tables, macros and you'd like to change a base data table within a PHP application.
Setup
Use composer to add this repository to your dependencies:
{
"require": {
"authenticode/spreadsheet": "dev-master"
}
}Examples
The following example demonstrates how to use Spreadsheet. The following is also
contained as example.php within the folder "examples/":
<?php
require_once('../vendor/autoload.php');
// Create a new instance
$dataTable = new Authenticode\Spreadsheet\Spreadsheet();
// Specify the source file
$in = 'spec.xlsx';
// Specify the output file
$out = 'test.xlsx';
// Specify the data for the worksheet.
$data = array(
array("Date" => new \DateTime('2014-01-01 13:00:00'), "Value 1" => 0, "Value 2" => 1),
array("Date" => new \DateTime('2014-01-02 14:00:00'), "Value 1" => 1, "Value 2" => 0),
array("Date" => new \DateTime('2014-01-03 15:00:00'), "Value 1" => 2, "Value 2" => -1),
array("Date" => new \DateTime('2014-01-04 16:00:00'), "Value 1" => 3, "Value 2" => -2),
array("Date" => new \DateTime('2014-01-05 17:00:00'), "Value 1" => 4, "Value 2" => -3),
);
// Attach the data table and copy the new xlsx file to the output file.
$dataTable->showHeaders()->addRows($data)->attachToFile($in, $out);
?>In this example the method "attachToFile" creates a new excel file. If you use this library within a web application you might prefer the "fillXLSX()" function which returns a string representation of the excel document. The following examples demonstrates this case within a laravel application
<?php
class ReportController extends Controller {
protected $dataTable;
public function __construct(\Authenticode\Spreadsheet\Spreadsheet $dataTable) {
$this->dataTable = $dataTable;
}
public function show($month) {
$data = DB::select('select date,value1,value2 from reporting where MONTH(date) = ?', array($month));
$path = storage_path() . '/reports/example.xlsx';
$xlsx = $this->dataTable->showHeaders()->addRows($data)->fillXLSX($path);
return Response::make($xlsx, 200, array(
'Content-Type' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
'Content-Disposition' => 'attachment; filename="report.xlsx"',
'Content-Length' => strlen($xlsx)
));
// ...
}
}
