php怎么限定一个函数的执行时间?
php如何限定一个函数的执行时间???
比如说,自定义了一个函数 ,这个函数运行的时间从1秒到60秒不等。现在要用到该函数但有一个问题是时间不能大于30秒,如果大于则程序报错,
现在有没有办法,在不修改原函数的情况下,来限制原函数 的运行时间,只要运行该函数,只要超过30秒,不管有没有成功都返回一个结果。
------解决方案--------------------
貌似,没有,可以用,试试
1.set_time_limit
2.fsockopen
3.curl
------解决方案--------------------
"在不修改原函数的情况下,...不管有没有成功都返回一个结果。"
我认为不可能,当然,除非你修改php的内部实现...
------解决方案--------------------
个人觉得不大可能。哪怕是你定义了时间跳转,函数应该也是会被继续执行完毕。
------解决方案--------------------
php从上往下执行 在函数开始记录一个时间 函数结尾记录一个时间,应该就能知道这个函数执行的时间了吧
