我的1.php里如果只写 echo "ok";
那么是可以正常显示OK的，但是如果我的１.ｐｈｐ里解一个循环１００万次的语句，并且每个循环间还sleep下（为了模拟1.php是一个会消耗较长时间的处理过程），那么很可能会在一段时间后蹦出提示框要保存此页面（1.php）？请问这个是怎么回事？怎么解决呢？

回复讨论(解决方案)

set_time_limit(0);

不行啊。现象一样，是不是apache里要设置什么呢？

设置下memory_limit试试

楼上的也试过了，不行，现象相同。

set_time_limit(0);
而且还要到你的APACHE配置文件php.ini中修改max_execution_time = 0

仍然不行。是不是浏览器端还有什么要设置的

仍然不行。是不是浏览器端还有什么要设置的
先你的APACHE配置文件php.ini中修改max_execution_time = 0，然后在程序中添加set_time_limit(0);
怎么可能有问题呢？上亿的数据我测试的时候，页面等待十几分钟都没挂掉。

下载说明你php脚本解析不了有没有可能是php 挂了

但是如果php挂了？怎么办呢？重装么
