如何避免php执行超时？
假设lnmp环境的php执行超时为5秒，现有一个函数里需要调用一个外部接口取数据。而调用这个外部接口有可能会超过5秒也取不完全部数据。是否有方法可以绕开5秒的执行超时时间呢？
php异步？
回复讨论(解决方案)
set_time_limit($n);
set_time_limit($n);
除了这个，还有其他思路嘛？
外部接口回调呢？
你不是要取的返回数据吗？那就要等他返回
如果你只发出请求，而不等待返回数据，也是可以的
当然你也就不可能得到实时数据了
若是实时性不高，那就异步吧

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
