README

PHP Library to only write and only XLSX files, in a fast and scalable way, box/spout package served as a basis.

Installation

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require threshold/php-excel

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Usage

Simple XLSX file generation with instant download:

$writer = new \Threshold\PhpExcel\Writer\Writer();
$writer
    ->setShouldCreateNewSheetsAutomatically(false)
    ->setShouldUseInlineStrings(true)
    ->openToBrowser("test.xlsx");

$sheet = $writer->getCurrentSheet();
$sheet
    ->setName("Statistics")
    ->setMergeRanges(["A1:B1"]);

$writer->addRow(\Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createRow([
    \Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createCell(
        "Statistics",
        (new \Threshold\PhpExcel\Writer\Entity\Style\Style())
            ->setCellAlignment(\Threshold\PhpExcel\Writer\Entity\Style\CellAlignment::CENTER)
            ->setFontBold())
]));

$writer->close();

Generating and saving a simple XLSX file to a given location:

$writer = new \Threshold\PhpExcel\Writer\Writer();
$writer
    ->setShouldCreateNewSheetsAutomatically(false)
    ->setShouldUseInlineStrings(true)
    ->openToFile("path/to/save/file/test.xlsx");

$sheet = $writer->getCurrentSheet();
$sheet
    ->setName("Statistics")
    ->setMergeRanges(["A1:B1"]);

$writer->addRow(\Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createRow([
    \Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createCell(
        "Statistics",
        (new \Threshold\PhpExcel\Writer\Entity\Style\Style())
            ->setCellAlignment(\Threshold\PhpExcel\Writer\Entity\Style\CellAlignment::CENTER)
            ->setFontBold())
]));

$writer->close();

Generate XLSX recursively, with only one file returned at the end:

// In each round, you must state that you are in the last round and how many rounds there will be in total.
$loopMax     = $request->query->get("loopMax", 1);
$loopCounter = $request->query->get("loopCounter", 1);
$writer      = new \Threshold\PhpExcel\Writer\Writer();
$writer
    ->setTempFolder("your/temp/folder/path/if/you/want")
    ->setShouldCreateNewSheetsAutomatically(false)
    ->setShouldUseInlineStrings(true)
    ->setDefaultRowStyle((new \Threshold\PhpExcel\Writer\Entity\Style\Style())
        ->setFontName("Calibri")
        ->setFontSize(11))
    ->setLoop($loopMax, $loopCounter); // Here you have to pass the circles,
                                       // from this it will know whether the writing will continue
                                       // or the file must be closed.
    
// $writer->close() until the last round returns the name of the temporary folder
// created in the first round in the temporary path,
// this must be specified here in order to continue generating the XLSX file.
if ($request->query->get("tempFolderName")) {
    $writer
        ->setTempFolderName($request->query->get("tempFolderName"));
}

$writer->openToFile("php://output")

$sheet = $writer->getCurrentSheet();
$sheet
    ->setName("Statistics");
    
if ($loopCounter === 1) {
    // The merged cells are counted from the last written row in each round,
    // so for example the cell merging of the address only needs to be entered in the first round.
    // In later rounds, the "A1:B1" cell merge will not apply to the first row, for example,
    // if we wrote 15 rows in the previous round, then cells A and B of the 16th row will be merged.
    // In this case, "A1:B1" will be as if we entered "A16:B16" in the first round.
    $sheet->setMergeRanges(["A1:B1"]);
    
    $writer->addRow(\Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createRow([
        \Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createCell("Statistics", (new \Threshold\PhpExcel\Writer\Entity\Style\Style())

                ->setBorderRight(\Threshold\PhpExcel\Writer\Entity\Style\Color::BLACK, \Threshold\PhpExcel\Writer\Entity\Style\Border::WIDTH_MEDIUM, \Threshold\PhpExcel\Writer\Entity\Style\Border::STYLE_SOLID)

            ->setFontName("Arial")
            ->setFontBold()
            ->setFontSize(20)),
        \Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createCell("", (new \Threshold\PhpExcel\Writer\Entity\Style\Style()) // Create empty cells with same Style to have borders
            ->setCellAlignment(\Threshold\PhpExcel\Writer\Entity\Style\CellAlignment::CENTER)
            ->setBorder((new \Threshold\PhpExcel\Writer\Entity\Style\Border())
                ->setBorderTop(\Threshold\PhpExcel\Writer\Entity\Style\Color::BLACK, \Threshold\PhpExcel\Writer\Entity\Style\Border::WIDTH_MEDIUM, \Threshold\PhpExcel\Writer\Entity\Style\Border::STYLE_SOLID)

                ->setBorderLeft(\Threshold\PhpExcel\Writer\Entity\Style\Color::BLACK, \Threshold\PhpExcel\Writer\Entity\Style\Border::WIDTH_MEDIUM, \Threshold\PhpExcel\Writer\Entity\Style\Border::STYLE_SOLID))
            ->setFontBold()->setFontSize(20))
    ]));
}

// We write this line in each round. In the first round it goes to cell "A2", in the second round to cell "A3" and so on.
$writer->addRow(\Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createRow([
    \Threshold\PhpExcel\Writer\Factory\WriterEntityFactory::createCell("Round: " . $loopCounter)
]));

if (($writerResponse = $writer->close()) === true) {
    header('Content-Type: application/zip');
    header('Content-Disposition: attachment; filename="test.xlsx"');
} else {
    header('Content-Type: application/json; charset=utf-8');
    echo json_encode(["tempFolderName" => $writerResponse]);
}
exit;

If you have generated multiple worksheets, you can now sort them alphabetically or in reverse order.

$writer->sortSheetsByName(); // abc sorting
$writer->sortSheetsByName(true); // abc reverse sorting

If you want to generate multiple worksheets, instead of using an if to determine whether you are in the first loop and using the $writer->getCurrentSheet() function to get the first worksheet, you can pass a second boolean parameter (the default is false) to the $writer->openToFile() or $writer->openToBrowser() functions, which will prevent the first worksheet from being created automatically. This way, you only need to use the $writer->addNewSheetAndMakeItCurrent() function to add a worksheet in each loop.

$writer->openToFile("example.xlsx", true);
$writer->openToBrowser("example.xlsx", true);
$sheet = $writer->addNewSheetAndMakeItCurrent();

If you generate Excel recursively and the submitted data determines the worksheet names each time, and it may happen that a worksheet with the same name needs to be created, you can use the $writer->getSheetByName() function, which searches the worksheets by name. If it has already been created, it returns that worksheet and sets it as current, if it does not, it creates a new one with the specified name, sets it as current and returns with it. And at the end, you can sort them in order.

$requestWorksheetNames = ["a", "b", "c"]; // first request
$requestWorksheetNames = ["d", "b", "f"]; // second request

// loop over the names each request
foreach ($requestWorksheetNames as $worksheetName) {
    $sheet = $writer->getSheetByName($worksheetName); // In the first request, none of them exist, so all of them are created, but in the second request, the "b" worksheet already exists, so no new one is created, but the existing one can be written further.
}
$writer->sortSheetsByName(); // And at the end, you can sort them in order.

If you want to add a header to your worksheets, which you only need to add once to the worksheet, you can use the $sheet->isNew() function as a check, which will only return true if this is the first time you've added the worksheet. If $writer->getSheetByName() returns it because you created it before, it will return false.

$sheet = $writer->getSheetByName("example");

if ($sheet->isNew()) {
    // add header
}
