标签:内存 serial cache 信息 excel ppp 读取 序列化 memcach 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 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 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 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 PHPExcel_CachedObjectStorageFactory::cache_to_discISAM; 4、保存在php://temp PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp; 5、保存在memcache中 PHPExcel_CachedObjectStorageFactory::cache_to_memcache 注意是加在new PHPExcel() 前面:如下 phpExcel大数据量情况下内存溢出解决 标签:内存 serial cache 信息 excel ppp 读取 序列化 memcach 原文地址:http://www.cnblogs.com/hopelooking/p/7686321.html $cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_memcache;
