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 'PHPExcel.php';

require_once 'PHPExcel/Writer/Excel5.php';

require_once("..includemysqlconn.php");

$sdate=$_POST["sdate"];//接受传递过来的生成时间段

$edate=$_POST["edate"];

//$sdate='2009-01-01';

//$edate='2009-04-01';

$cancel_time=date("YmdHis");



$data=new MysqlConn();

$data->connect();

$sql="select * from employee_addminus where (oper_time between '$sdate' and '$edate') 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('月增减变动报表');



//*************************************

//

//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('A')->setWidth(20);

$objActSheet->getColumnDimension('B')->setWidth(10);

$objActSheet->getColumnDimension('C')->setWidth(6);

$objActSheet->getColumnDimension('D')->setWidth(20);

$objActSheet->getColumnDimension('E')->setWidth(12);

$objActSheet->getColumnDimension('F')->setWidth(10);

$objActSheet->getColumnDimension('G')->setWidth(20);

$objActSheet->getColumnDimension('H')->setWidth(18);

$objActSheet->getColumnDimension('I')->setWidth(12);

$objActSheet->getColumnDimension('J')->setWidth(8);

$objActSheet->getColumnDimension('K')->setWidth(8);

$objActSheet->getColumnDimension('L')->setWidth(12);

$objActSheet->getColumnDimension('M')->setWidth(10);

$objActSheet->getColumnDimension('N')->setWidth(10);



$objActSheet->getRowDimension(1)->setRowHeight(30);

$objActSheet->getRowDimension(2)->setRowHeight(27);

$objActSheet->getRowDimension(3)->setRowHeight(16);



//设置单元格的值

$objActSheet->setCellValue('A1', '章贡区医疗保险局职工月增减变动报表');

//合并单元格

$objActSheet->mergeCells('A1:N1');

//设置样式

$objStyleA1 = $objActSheet->getStyle('A1');

$objStyleA1->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

$objFontA1 = $objStyleA1->getFont();

$objFontA1->setName('宋体');

$objFontA1->setSize(18);

$objFontA1->setBold(true);



//设置居中对齐

$objActSheet->getStyle('A2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

$objActSheet->getStyle('B2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

$objActSheet->getStyle('C2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

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);
