PHP uses the Gettimeofday function to return the current time and store it in an associative array.
This article mainly introduces PHP using the Gettimeofday function to return the current time and stored in the associative array method, involving
Time () provides a second level of accuracy

2. Function prototype
time_t Time (time_t * timer)
The function returns the number of seconds starting from Tc1970-1-1 0:0:0 to now
Use the time () function with other
Use C language for timingIn user space, you can use the C language function gettimeofday to get the time. The call format is:
# Include Int gettimeofday (struct timeval * TV, struct timezone * tz );Int settimeofday (const struct timeval * TV, const
