php 更新数据库中断的解决方法

900limitphpsettimeinterruptfunctiondatabasemethodrenewofsolvethis

即可解决:
set_time_limit(900);
这个函数指定了当前所在php脚本的最大执行时间,
虽然设定值是900秒,实际上
最大执行时间=php.ini里的max_execution_time数值 - 当前脚本已经执行的时间 + 设定值
假如php.ini里的max_execution_time=30,当前脚本已经执行10秒,则:
最大执行时间=30-10+900=920秒。
经过如此修改后,PHP脚本成功更新200000条记录。

以上是在LAPP环境中通过的。
另外,据说这个方法在windows环境无效,在windows环境需要指定php.ini里的max_execution_time数值。
没有测试这种情况。
