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:

<?php
require_once &#39;PHPExcel.php&#39;;
require_once &#39;PHPExcel/Writer/Excel5.php&#39;;
require_once ("..includemysqlconn.php");
$sdate = $_POST["sdate"]; //接受传递过来的生成时间段
$edate = $_POST["edate"];
//$sdate=&#39;2009-01-01&#39;;
//$edate=&#39;2009-04-01&#39;;
$cancel_time = date("YmdHis");
$data = new MysqlConn();
$data->connect();
$sql = "select * from employee_addminus where (oper_time between &#39;$sdate&#39; and &#39;$edate&#39;) and isCanceled=0";
// 创建一个处理对象实例
$objExcel = new PHPExcel();
// 创建文件格式写入对象实例, uncomment
$objWriter = new PHPExcel_Writer_Excel5($objExcel);
//设置文档基本属性
$objProps = $objExcel->getProperties();
$objProps->setCreator("章贡区医疗保险局");
$objProps->setLastModifiedBy("章贡区医疗保险局");
$objProps->setTitle("章贡区医疗保险局职工月增减变动报表");
$objProps->setSubject("章贡区医疗保险局职工月增减变动报表");
$objProps->setDescription("章贡区医疗保险局职工月增减变动报表");
$objProps->setKeywords("章贡区医疗保险局职工月增减变动报表");
$objProps->setCategory("变动报表");
//*************************************
//设置当前的sheet索引，用于后续的内容操作。
//一般只有在使用多个sheet的时候才需要显示调用。
//缺省情况下，PHPExcel会自动创建第一个sheet被设置SheetIndex=0
$objExcel->setActiveSheetIndex(0);
$objActSheet = $objExcel->getActiveSheet();
//设置当前活动sheet的名称
$objActSheet->setTitle(&#39;月增减变动报表&#39;);
//*************************************
//
//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
$objActSheet->getColumnDimension(&#39;A&#39;)->setWidth(20);

//设置单元格的值

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:

$cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_phpTemp;   

$cacheSettings = array( ' memoryCacheSize '  => '8MB'   

                  );   

PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings);  

第5种,代码如下:

$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_memcache;   

$cacheSettings = array( 'memcacheServer'  => 'localhost',   

                   'memcachePort'    => 11211,   

                  'cacheTime'       => 600   

                 );   

PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings);
