that you do not adjust the max_execution_time, but only in the PHP program: Set_time_limit (0); Make temporary adjustments. Setting 0 means there is no time limit. Of course, from the point of view of program execution, set 0 is to solve the timeout problem, but in fact is not a good solution, if the program supports the continuation of the breakpoint, then set 600 seconds or 3,600 seconds also seems to be a better idea, time-out automatic breakpoint continued to pass.
