MySQL PHP不会将大数据导出到Excel
我想从mysql表名 personen 导出一个excel文件，该文件有35列，它包含大约950多条记录，如果我通过在查询中使用限制导出大约300行，它会生成完美的excel但是当我尝试导出500行或更多行时，它会在0字节的excel文件
这是我的代码
ini_set('memory_limit','1024M');
require_once 'PHPExcel.php';
require_once 'db_config.inc.php';

PHPExcel认为这些单元格值中有一个是公式，即以=开头的字符串值;但这并不是一个有效的Excel公式，否则PHPExcel在尝试评估公式时不会失败。
您需要确定数据库中的值是什么，并确保使用setCellValueExplicit()方法告诉PHPExcel它应该被视为字符串而不是公式
