PHP大量数据循环时内存耗尽问题的解决方案
最近在开发一个PHP程序时遇到了下面的错误:PHP Fatal error: Allowed memory size of 268 435 456 bytes exhausted错误信息显...
分析:开发的这个程序是要用一个foreach循环语句在一个有10万条记录的表里全表搜索具有特定特征的数据,
也就是说,一次要把10万条数据取出,然后逐条检查每天数据。可想而知,10万条数据全部加载到内存中,内存不爆才怪.
缓冲查询和非缓冲查询(Buffered and Unbuffered queries)</a>。
PHP的查询缺省模式是缓冲模式。也就是说,查询数据结果会一次全部提取到内存里供PHP程序处理。这样给了PHP程序额外的功能。比如说,计算行数,将 指针指向某一行等。
更重要的是程序可以对数据集反复进行二次查询和过滤等操作。但这种缓冲查询模式的缺陷就是消耗内存,也就是用空间换速度。
相对的,另外一种PHP查询模式是非缓冲查询,数据库服务器会一条一条的返回数据,而不是一次全部返回,这样的结果就是PHP程序消耗较少的内存,
但却增加了数据库服务器的压力,因为数据库会一直等待PHP来取数据,一直到数据全部取完。
很显然,
缓冲查询模式适用于小数据量查询,而非缓冲查询适应于大数据量查询。
对于PHP的缓冲模式查询大家都知道,下面列举的例子是如何执行非缓冲查询API。
