In this case, do I have to refresh the page? No side php only runs once. how can you obtain the later time of your date value.
Therefore, I personally suggest using JavaScript:
[Dynamic time] you can add your url in timetip.

HTML code

Script window. onload = running; // run the running () function running () {timeshow () ;}function addzero (param) {var str = ""; if (param <10) str = "0" + param; else str = param; return str;} function timeshow () {var today = new Date (); var y = today. getFullYear (); var m = today. getMonth () + 1; // when the hour is taken out, + 1 var d = today. getDate (); var h = today. getHours (); var I = today. getMinutes (); var s = today. getSeconds (); var a = today. getDay (); var week = ""; switch (a) {case 0: week = "Sunday"; break; case 1: week = "Monday"; break; case 2: week = "Tuesday"; break; case 3: week = "week"; break; case 4: week = "Thursday"; break; case 5: week = "Friday "; break; case 6: week = "Saturday"; break;} // determine the current time period [color = # FF0000] var timetip = ""; if (h <12) {// alert (h); if (h> 6) {timetip = "morning";} else if (h> 0 & h <6) | h = 6 | h = 0) {timetip = "morning";} // end if} else if (h = 12) {timetip = "noon" ;}else {if (h> 12 & h <18) {timetip = "afternoon ";} else if (h> 18 & h <24) | h = 18) {timetip = "evening ";} // end if} // end if [/color] m = addzero (m); d = addzero (d); h = addzero (h ); I = addzero (I); s = addzero (s ); var riqi = week + "" + y + "year" + m + "month" + d + "day" + ""; // assign the year, month, day, and week to the riqi variable var sfm = h + ":" + I + ":" + s; // assign the hour, minute, and second value to the sfm variable [color = # FF0000] var sp = document. getElementById ("showtime"); // gets the object SPNS of the location to be placed. innerHTML = riqi + y + "-" + m + "-" + d + "" + sfm; // put the time in the page [/color] setTimeout ("timeshow () ", 1000); // runs the timesho () function once every one second} script
