PHP Add Hour to beginning of day

Question

Given a date and an hour, I want to append that hour onto that date.

E.g: Given hour 3 and date 2017-05-30 I want: 2017-05-30 03:00:00

<?php

$d1 = date('Y-m-d');
$hour = 3;
$new_time = date("Y-m-d H:i:s", strtotime('+' . $hour .' hours', $d1));
echo $new_time;

?>

When running the following code I get:

Notice: A non well formed numeric value encountered on $new_time = date("Y-m-d H:i:s...

How can I get the proper output?

Do you want 3 hours from now, or just `03:00:00` of that date? — aynber, May 30 '17 at 14:35

try strtotime() with + hour like below :

<?php
    $d1 = date('Y-m-d');
    $new_time = date("Y-m-d H:i:s", strtotime($d1."+ 3 hour")); //here you can change the hour according to your need as now it is + 3
    echo $new_time;

Yeah I noticed you tag the OP in all the answers you're giving (not just this one). You dont have to do that. It's already implied that an answer on Stackoverflow is a reaction to the question. – Loko May 30 '17 at 14:38
@Loko probably his *"signature"* lol – Funk Forty Niner May 30 '17 at 14:39
wonder what'll happen if and when all of those OP's change their profile names lol!!! they'll be wondering who you're talking to haha! – Funk Forty Niner May 30 '17 at 14:40
now i think its fine m i right ? – lazyCoder May 30 '17 at 14:41
@Fred-ii- Given that he has 1380 reputation, he probably knows no one tags OP in an answer, but he still does it so it probably is his "signature". I've also noticed he starts every answer with:"@user try this:" and thats it. – Loko May 30 '17 at 14:41
@Loko Right... and like I said in an above comment;, about if and when someone changes their profile name lol – Funk Forty Niner May 30 '17 at 14:42

@ Loko yeah this is my signature man – lazyCoder May 30 '17 at 14:42

@Fred-ii- yeah exactly, the intro of the answer would make no sense in that case. – Loko May 30 '17 at 14:43
@BunkerBoy Loko didn't get that ping; you've a space after the @ – Funk Forty Niner May 30 '17 at 14:43
what is wrong with tagging the OP name in the answer ? – lazyCoder May 30 '17 at 14:45
@BunkerBoy I already addressed that twice which could happen and it does happen that people change their profile names. It's also not needed. – Funk Forty Niner May 30 '17 at 14:46
let it finish buddy i'll remember to Fred -ii- ok ;-) – lazyCoder May 30 '17 at 14:47

You can use Datetime and add DateInterval:

$now = new DateTime(); //current date/time
$now->add(new DateInterval("PT3H"));
$new_time = $now->format('Y-m-d H:i:s');
echo $new_time;

DateInterval receives as parameter a string, if you want to learn more about the way you can format the intervals check here.

You can simply add the time that you need to add by strtotime($time) + $yourtimeinseconds;

Here's the Eval Link

Code :

<?php
$time = date("Y-m-d H:i:s");
$hour = 3*60*60; // To Seconds
$time = strtotime($time) + $hour; // Add 1 hour
$time = date('Y-m-d H:i:s', $time); 
echo $time;

All of the other answers are for if you want 3 hours from the current time. If you just want 3am, then just append the time, no math necessary.

$time = date('Y-m-d 03:00:00');
