PHP - Php Date / Time Problem

Hi,

I'm preparing a code for an automated email, but the date time is not working correctly. I wanted to do a cron scheduler that emails people twice a day - 9am and 9pm. 9am sends email about records logged starting 9pm yesterday to 9am, while 9pm sends email about records logged from 9:01am to 9:00pm. The database uses date/time, so I was doing an if statement of date time, but I wasn't getting the result I wanted.

Sometimes the $now time is not within the yesterday 9pm to the 9pm today range. I don't know what I'm doing wrong, but I'm sure that it has something to do with the if statement, as the some of the $now time enters the else statement

Here is my code:


<?php
$today = date('Y-m-d 00:00:00');
$nineyesterday = date('Y-m-d H:i:s', mktime(date("H") - (date("H") + 6), date("i") - date("i"), date("s") - date("s"), date("m") , date("d"), date("Y")));
$now = date('Y-m-d H:i:s', mktime(date("H") + 13, date("i"), date("s"), date("m") , date("d"), date("Y")));
$nineam = date('Y-m-d 09:00:00');
$nine30 = date('Y-m-d 09:30:00');
$ninepm = date('Y-m-d 18:00:00');
echo '9pm yesterday: '.$nineyesterday;
echo '<br/>';
echo '9am: '.$nineam;
echo '<br/>';
echo '9pm: '.$ninepm;
echo '<br/>';
echo 'now: '.$now;
echo '<br/>';


if ((strtotime($now) > strtotime($nineyesterday)) and  (strtotime($now) <= strtotime($nineam)))
{
//count the answers by yes or no
echo 'am';

}
elseif ((strtotime($now) > strtotime($nineam)) and  (strtotime($now) <= strtotime($ninepm)))
{
//count the answers by yes or no
echo 'pm';
}
else
{
echo 'error';
}
?>


Thanks in advance

Hey guys,
How would I go about subtracting Today from a previous day to find the difference?

For example, I want to subtract TODAY from a previous date in my database, to determine if the difference is greater than 1 day.

Any ideas? I tried doing the subraction in TIMESTAMPS, but when I convert the date back to Y-m-d H:i:s, I got some weird year and time.
 

Hi,
I've done a search and cant find anything related to my problem.
I have a newsfeed on my site and i want it to display with the latest news at the top.
I have this code:
Code: [Select]
$get_news = "SELECT title, text, DATE_FORMAT(datetime, '%e %b %Y at %T') AS datetime FROM newsfeed ORDER BY datetime DESC";
This works fine on one of my sites but on another i've just hit a problem. It seems to sort only by the day, not the rest of the date.
I made a news post today with date and time of "27 Mar 2011 at 12:54:02" but a post from "28 Jan 2011 at 19:59:52" is above it.

Any ideas why this is happening?

Thanks,
Alex

I want to users can setup time difference in hours, but I dont know how to solve this. Here is script for localtime:

  $date_format = 'd.m.Y H:i';
  $timezone = new DateTimeZone("Europe/Berlin");
  $date = new DateTime();
  $date->setTimezone($timezone);
echo "<div align='right'> Today is " . $date->format("$date_format") . "</div>";


Now I have $user_time in config and users can change this value (example: +1 hours, -3 hours etc...). Users time settings ($user_time) are saved in database.

How to display time based on user_time (ex. $date->format("$date_format")  ) to display message like this:
Today is 16.09.2010 18 (+$user_time) : 40

PHP date and time function is not showing correct time on my local system

I have the following php code

date_default_timezone_set("Africa/Lagos");

$date = date('d-m-y h:i:s');

echo "Server Time ".$date ."<br>";

echo "The time is " . date("h:i:sa")."<br>";

$current_datetime = date("Y-m-d") . ' ' . date("H:i:s", STRTOTIME(date('h:i:sa')));

echo "Current time1: ".$current_datetime . "<br>";

 

Output

Server Time 21-05-21 09:55:39
The time is 09:55:39am
Current time1: 2021-05-21 09:55:39

 

Expected Output

Server Time 21-05-21 10:55:39
The time is 10:55:39am
Current time1: 2021-05-21 10:55:3

 

Any help would be appreciated.
