Question

以下是我的代码。我将数据作为一个包含2个部分的字符串。第一部分是关于Excel工作表的标题。第二部分是关于实际数据。它们由特殊的分隔符分隔。

同样，第二部分（实际数据）用＆＃39; \ n＆＃39;对于每一行，每列再次用分隔符＆＃39; |＆＃39;。

分隔

现在，如果我点击下载，excel将在1分20秒后生成..请帮助我找到罪魁祸首，因为我是php的新手。

我在这里使用PHPExcel_IOFactory插件..

if（！empty（$ json_decodeArr）） $ dataExists = 1; 其他 $ dataExists = 0;

$service_name = $params['service_name'];
$company_name = $params["company_name"];
    $language = $params["language"];

$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
$cacheSettings = array(' memoryCacheSize ' => '32MB');
PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings);

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

if (isset($GLOBALS[$service_name]["TEMPLATE_NAME"]) && $GLOBALS[$service_name]["TEMPLATE_NAME"] != '') {
    $template = $GLOBALS[$service_name]["TEMPLATE_NAME"];
    $ext = $GLOBALS[$service_name]["TEMPLATE_NAME_EXT"];
    $path = $GLOBALS[$service_name]["TEMPLATE_PATH"];
    $filepath = $path . $template.$language . "." . $ext;
    try {
        //load Excel template file
        $objPHPExcel = PHPExcel_IOFactory::load($filepath);
    } catch(Exception $e) {
        die('Error loading file ' . $e -> getMessage());
    }

} else {
    $template = $GLOBALS["TEMPLATE_BLANK"];
    $ext = $GLOBALS[$service_name]["TEMPLATE_BLANK_EXT"];
    $path = $GLOBALS["TEMPLATE_BLANKPATH"];
    $filepath = $path . $template . "." . $ext;
    try {
        //load Excel template file
        $objPHPExcel = PHPExcel_IOFactory::load($filepath);
    } catch(Exception $e) {
        die('Error loading file ' . $e -> getMessage());
    }
}

$temp_array = array();

//Named Configuration XLS Generation

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
unset($objPHPExcel);
ob_start(); 
$objWriter -> save("php://output");
ob_flush();
exit ;

PHPExcel_IOFactory :: createWriter和Save花了一分多钟写一个文件
