關於 PHP 導出 excel csv 經常使用的有 PHPexcel ,本文整理了一些其餘方案。

高性能 Excel 擴展

sudo apt-get install -y zlib1g-dev
git clone https://github.com/jmcnamara/libxlsxwriter.git
cd libxlsxwriter
make && sudo make install

for($index = 0 ; $index < 10000 ; $index++){
    $data[$index] = ['viest', 23, 666666666666666666, '銀河市地球區程序村PHP組菜鳥灣66號', 15666666666];
}

$timeStart = microtime(true);

$config = [
    'path' => '/vagrant/',
];

$excel = new \Vtiful\Kernel\Excel($config);

$textFile = $excel->fileName("test.xlsx")
    ->header(['name', 'age', 'id_card', 'address', 'phone'])
    ->data($data)
    ->outPut();

$timeEnd = microtime(true);
$time = $timeEnd - $timeStart;

echo "導出Excel花費: $time seconds\n";

laravel-excel

composer require maatwebsite/excel
// 導出 Excel 並能直接在瀏覽器下載https://laravel-china.org/topics/1918/extension-how-to-deal-with-the-excel-file-in-the-laravel-project 
# $export_file_name = 要生成的文件名
Excel::create($export_file_name, function ($excel) {
    $excel->sheet('Sheetname', function ($sheet) {
        $sheet->appendRow(['data 1', 'data 2']);
        $sheet->appendRow(['data 3', 'data 4']);
        $sheet->appendRow(['data 5', 'data 6']);
    });
})->download('xls');

// 導出 Excel 並存儲到指定目錄
Excel::create($export_file_name, function ($excel) {
    $excel->sheet('Sheetname', function ($sheet) {
        $sheet->appendRow(['data 1', 'data 2']);
        $sheet->appendRow(['data 3', 'data 4']);
        $sheet->appendRow(['data 5', 'data 6']);
    });
})->store('xls', $object_path); 

問題：
1. var_dump($reader->toArray());//第一行內容爲key，若是爲中文，須要修改excel.php的 'to_ascii' => false, 
2.大數字變成科學計數 如 11111111111 顯示成 1.11111E+29
導出 excel 錯誤
PHPExcel_Calculation_Exception: Q5!A65 → Formula Error: An unexpected error occured in /application/www/web_git-pull/vendor/phpoffice/phpexcel/Classes/PHPExcel/Cell.php:291

在excel中一個單元格若是是以「=」開頭，則說明這個單元格是根據其餘單元格的值算出來的，「=」後面必須跟着一個合法的表達式,而那個字符串是用戶的輸入，很明顯不該該是一個合法的表達式，因此應該在代碼中過濾掉或者 $str = 「\t」.$str;

單文件

//https://github.com/mk-j/PHP_XLSXWriter/tree/master/examples 有不少測試代碼
include_once("xlsxwriter.class.php");
ini_set('display_errors', 0);
ini_set('log_errors', 1);
error_reporting(E_ALL & ~E_NOTICE);

$filename = "example.xlsx";
// 
for($index = 0 ; $index < 250000 ; $index++){
    $data[$index] = ['viest', 23, 666666666666666666, '銀河市地球區程序村PHP組菜鳥灣66號', 15666666666];
}

$timeStart = microtime(true);

$writer = new XLSXWriter();
$writer->writeSheet($data);
$writer->writeToFile('example.xlsx');

$timeEnd = microtime(true);
$time = $timeEnd - $timeStart;

echo "導出Excel花費: $time seconds\n";
echo '#'.floor((memory_get_peak_usage())/1024/1024)."MB"."\n";

Excel處理包

//https://github.com/bean-du/excel
  $writer = new ExcelWriter();
    for ($i = 0; $i < 100; $i++){
        for ($j = 0; $j < 10; $j++){
            $data[$i][$j] = 'test ['.$i.']+['.$j.']';
        }
    }
    $writer->setWidth(range('A','J'))
        ->setValue($data)
        ->setFormat('xls')
        ->setAlignment(array('A1','C1'),'CENTER')
        ->setBackgroundColor(array('A1','C1'),'#ccccc')
        ->setAlignment(array('A2','C2'),'RIGHT')
        ->setActiveSheetName('Bean')
        ->outPut('test.xls');

down csv

function export_csv($filename)
{
header("Content-type:text/csv");
header("Content-Disposition:attachment;filename=".$filename);
header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
header('Expires:0');
header('Pragma:public');
