PHP determines 2 methods for a specified time period

Sometimes we need to do a task at a certain time of day, or do different tasks in different hours of the day, and how to do that with PHP, and the following two examples can solve this problem

One, contains the hour and minute Judgment code as follows: Date_default_timezone_set ("Asia/shanghai"); $time = intval (Date ("Hi")); if ($time > "a" && $time < "1130") {//code} Two, only the judge hour code is as follows: Date_default_timezone_set ("Asia/shanghai" );  if (Date (' G ') <8 | | date (' g ') >17) {//code} $H = intval (Date ("H")); if ($h > | | $h < 7) {echo ' Here is the first task ';} else {echo ' Here is the second task ';}
