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);

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);
