MySQL PHP 未将大数据导出到 Excel

Question

我想从 mysql table name personen 导出一个 excel 文件，它有 35 列，包含大约 950 多条记录，如果我通过在查询中使用限制导出大约 300 行，它会完美地生成 excel 但是当我尝试导出 500 行或更多行时，它会在 0 字节 excel 文件

这是我的代码

ini_set('memory_limit','1024M');
require_once 'PHPExcel.php';  
require_once 'db_config.inc.php';
// Create new PHPExcel object  
$objPHPExcel = new PHPExcel();  

// Set properties  
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw")  
->setLastModifiedBy("Habib ul Haque")  
->setTitle("Office 2007 XLSX Test Document")  
->setSubject("Office 2007 XLSX Test Document")  
->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")  
->setKeywords("office 2007 openxml php")  
->setCategory("Test result file");

Answer 1

PHPExcel 认为其中一个单元格值中包含公式，即以 = 开头的字符串值；但这实际上作为 Excel 公式无效，否则 PHPExcel 在尝试计算公式时不会失败。

您需要从数据库中确定该值是什么，并确保您使用 setCellValueExplicit() 方法告诉 PHPExcel 它应该被视为字符串而不是公式
