phpExcel数据内存溢出解决办法

时间:2015-01-23  来源:西部数据  作者:西部数据

云平台需要进行excel数据批量导入,使用的是phpExcel工具,小曲同学的代码都写好后,小数据量下测试都没有问题,可是一到正式环境下,数据超过千条,一行十列为一条数据,就报内存超出.

先看实例,代码如下:

  1. <?php  
  2. require_once 'PHPExcel.php';        
  3. require_once 'PHPExcel/Writer/Excel5.php';     
  4. require_once("..includemysqlconn.php");    
  5. $sdate=$_POST["sdate"];//接受传递过来的生成时间段    
  6. $edate=$_POST["edate"];    
  7. //$sdate='2009-01-01';    
  8. //$edate='2009-04-01';    
  9. $cancel_time=date("YmdHis");    
  10.    
  11. $data=new MysqlConn();    
  12. $data->connect();    
  13. $sql="select * from employee_addminus where (oper_time between '$sdate' and '$edate') and isCanceled=0";    
  14.        
  15. // 创建一个处理对象实例        
  16. $objExcel = new PHPExcel();        
  17.        
  18. // 创建文件格式写入对象实例, uncomment        
  19. $objWriter = new PHPExcel_Writer_Excel5($objExcel);       
  20.      
  21. //设置文档基本属性        
  22. $objProps = $objExcel->getProperties();        
  23. $objProps->setCreator("章贡区医疗保险局");        
  24. $objProps->setLastModifiedBy("章贡区医疗保险局");        
  25. $objProps->setTitle("章贡区医疗保险局职工月增减变动报表");        
  26. $objProps->setSubject("章贡区医疗保险局职工月增减变动报表");        
  27. $objProps->setDescription("章贡区医疗保险局职工月增减变动报表");        
  28. $objProps->setKeywords("章贡区医疗保险局职工月增减变动报表");        
  29. $objProps->setCategory("变动报表");        
  30.        
  31. //*************************************        
  32. //设置当前的sheet索引,用于后续的内容操作。        
  33. //一般只有在使用多个sheet的时候才需要显示调用。        
  34. //缺省情况下,PHPExcel会自动创建第一个sheet被设置SheetIndex=0        
  35. $objExcel->setActiveSheetIndex(0);        
  36. $objActSheet = $objExcel->getActiveSheet();        
  37.        
  38. //设置当前活动sheet的名称        
  39. $objActSheet->setTitle('月增减变动报表');        
  40.        
  41. //*************************************        
  42. //        
  43. //设置宽度,这个值和EXCEL里的不同,不知道是什么单位,略小于EXCEL中的宽度

小数据量没问题,但是大数据量时出现数据导入内存溢出经过查询之后,找到了解决办法.

版本:1.7.6,在不进行特殊设置的情况下,phpExcel将读取的单元格信息保存在内存中,我们可以通过如下代码:

PHPExcel_Settings::setCacheStorageMethod();

来设置不同的缓存方式,已达到降低内存消耗的目的.

1、将单元格数据序列化后保存在内存中,代码如下:

PHPExcel_CachedObjectStorageFactory::cache_in_memory_serialized; 

2、将单元格序列化后再进行Gzip压缩,然后保存在内存中,代码如下:

PHPExcel_CachedObjectStorageFactory::cache_in_memory_gzip; 

3、缓存在临时的磁盘文件中,速度可能会慢一些,代码如下:

PHPExcel_CachedObjectStorageFactory::cache_to_discISAM;

4、保存在php://temp,代码如下:

PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;  

5、保存在memcache中,代码如下:

PHPExcel_CachedObjectStorageFactory::cache_to_memcache

举例,第4种方式,代码如下:

  1. $cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_phpTemp;   
  2. $cacheSettings = array' memoryCacheSize '  => '8MB'   
  3.                       );   
  4. PHPExcel_Settings::setCacheStorageMethod($cacheMethod$cacheSettings);  

第5种,代码如下:

  1. $cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_memcache;   
  2. $cacheSettings = array'memcacheServer'  => 'localhost',   
  3.                        'memcachePort'    => 11211,   
  4.                       'cacheTime'       => 600   
  5.                      );   
  6. PHPExcel_Settings::setCacheStorageMethod($cacheMethod$cacheSettings);
