PHP - Difference Between Datetimes
I'm trying to subtract get the total number of days between two dates. I have been trying the DateTime date_diff method and the strtotime methods. I have it working mostly; but I have a problem with if the value should be negative. I've tried the invert() on the value that comes back from the date_diff() function but get errors. To sum up what I'm trying to do is:
if ( $diff === 0 )
//retrieve expected complete time
if ( isset( $stat[ 'expected_complete_time' ] ) ) {
$today = new DateTime("now");
$expected_complete_time = new DateTime($stat[ 'expected_complete_time' ]);
$today->setTime(12, 0, 0);
$expected_complete_time->setTime(12, 0, 0);
//calculate difference
$eta = date_diff($expected_complete_time, $today)->format("%d");;
//future
if ($today > $expected_complete_time) {
$eta = '+' . $eta;
//today
} elseif ($eta === '0') {
$eta = 'Today';
//overdue
} else {
$eta = 'LATE:-' . $eta;
}
} else
$eta = '';
Similar TutorialsHello I have 2 datetimes...both are inside a database. The datetimes are not unix time they are regular date\times. So for instance...in the database I have a field called Login_time which is 2012-01-30 02:43:13 I am taking the current time in the same format with the following code Code: [Select] $curDate = date("Y-m-d H:i:s", time()); The problem is that I can't figure out how to tell the exact minutes for the 2 date\time intervals. Code: [Select] //find out if the ip address is inside the database $doesIpExsist = mysql_query("Select * from login_information where IP_Address like '$ip'", $link); $num_rows = mysql_num_rows($doesIpExsist); echo "$num_rows Rows\n"; if ($num_rows == 0) { //create the field inside the database $ip_query = "INSERT INTO login_information (IP_address, `Login_attempts`, Login_time, Total_login_attempts) VALUES ('$ip', '1', NOW(), '1')"; $ip_result = mysql_query($ip_query, $link) or die (mysql_error()); } else //the fields alaready exsist { $curDate = date("Y-m-d H:i:s", time()); echo $curDate; include ('timefunction.php'); echo "<br>"; echo "IP ".$ip; echo "<br>"; $select_ip_id = "SELECT ID from login_information where IP_address like '127.0.0.1'"; //$select_ip_id = "SELECT ID from login_information where IP_address like '$ip'"; echo $select_ip_id; $ip_error = mysql_query($select_ip_id, $link) or die (mysql_error()); foreach ($row = mysql_fetch_array($ip_error, MYSQL_ASSOC) as $key => $value) { echo dateDiff('$curDate', '$get_ip_error') .

Can you tell me what i am doing wrong on this issue. Considering security, is there a disadvantage in using $_REQUEST? Hi, In Php , What is the different ebtween abc() and @abc() ??? Please advice . This is going to seem like a stupid question but I'm curious about it anyway. Isn't isset and !empty do the same? Actually what's the difference between Code: [Select] if(...) and Code: [Select] if(isset(...) I am working with wordpress and I see a lot of "if" statements done like this if(condition): do something endif; I have always done it like so if(condition) { do something } what is the difference? does the first method have any advantages over the second method? Hey guys im stuck in a bind and need some input. What im trying to do is display a number based from community levels. ex: This user need another 2 tasks to get next level. here are the levels 1- 0-2 task new 2- 2-5 tasks beginer 3- 5-7 tasks pro 4- 7+ tasks advanced The way it works is by two different tasks. basicly i wanna know which is the higher number in the tasks either how many posts or comment and figure out based on our levels how many tasks he need to complete in order for him to reach the next level. the first query sees how many post this user has the second check how many comment he has I wanna take the highest number and that belongs to whicheber catgory, do a calculation. and have this kind of output This user is level 2 and need 1 more task to reach the next level. Like i know if he need one more that he has 4 tasks done. I know im all over the place with this one im just trying to get someone who might have an idea of my issue and point me in the right direction. Either if this is a known ?? does this procedure has a specific name anything will help me. Problem; Need to check to see if someone who requested a password re-set has done so with in 24hrs. IF not- then it needs to prompt them to re-submit the request and deletes the previous re-submit code sent to them in their email. I have everything else figured out (deleting re-set code) but I have not figured the checking of if they have done so within the 24hr time period. Please tell me if the code below will accurately tell me if they complied with the 24 hour rule. $time1 = '1284675867';// logged at the time of password re-set request. Retrieved from database $time2 = time();// captured in script when they actually re-set their password $difference_between = $time2 - $time1; if($difference_between >= '5,200,000') { echo "Sorry- you have exceeded the 24 hr rule and need to re-submit your request"; } Compared to all that I have seen.........it appears rather simplistic. Am I missing something or will this simple approach work? hiii, Im wanting to calculate the time difference between $out2 and $in2 and out put it into a spreadsheet: Code: [Select] $m=0; while ($m < $num9) { $fullname=mysql_result($result9,$m,"username"); $date=mysql_result($result9,$m,"date"); $in1=mysql_result($result9,$m,"in1"); $out1=mysql_result($result9,$m,"out1"); $in2=mysql_result($result9,$m,"in2"); $out2=mysql_result($result9,$m,"out2"); $out2f=date("G:i:s",strtotime($out2)); $in2f=date("G:i:s",strtotime($in2)); echo date("D",strtotime($date)). "\t" . $fullname . "\t" . $in1 . "\t". $out1 . "\t" . $in2 . "\t" . $out2 . "\t" . date("G:i:s",strtotime($out2f-$in2f)) . "\t" . "\n"; $m++; } header("Content-disposition: attachment; filename=spreadsheet.xls"); why does this code return 00:00:00 ? Basically I am using DATETIME to store the time in which a row was input. Format - 2010-11-13 21:31:53 How would I get the current time of page load and compare it to the database row "2010-11-13 21:31:53" then output the difference. Example $sqlresult = 2010-11-13 21:31:53; $currentTime = (GET CURRENT DATE+TIME = (2010-11-13 21:31:55) ); Output - This was posted 2 minute's ago. Thank you in advance. Any help would be greatly appreciated. Hi, I am trying to get the difference in time in mins, hours etc thingy. Now, for some reason I cannot get the right minutes or hours difference between two time stamps. Here is my code: Code: [Select] $postedTime=strtotime($comment_from_db->date_posted); $currentTime=time(); $mins=floor(($currentTime-$postedTime)/60); if($mins<=1){ echo $mins." minute ago by"; }elseif($mins>1){ if($mins>60){ $hrs=floor($mins/60); if($hrs>24){ }else{ if($hrs<2){ echo $hrs. " hour ago by"; }else{ echo $hrs. " hours ago by"; } } }else{ echo $mins." minutes ago by"; } } Now, for a comment posted like 25 mins ago it shows it was posted 4 hours ago. For a comment posted around 10 hours ago it shows it was posted 16 hours ago. What is the problem here? I was doing a test and checked the time in seconds after an interval of 2 mins. Here are the results: Comment posted: 1306669490 Current time: 1306683920 The difference is around 14430. This is not equal to 2 minutes. So, I am starting to think if the time I am getting is wrong? Should it have 10 digits? or less? I am not sure what is going on. Please, advice. Thanks. <?php $i = 2; $i = $i++; echo $i; ?>Output of above code is 2. <?php $i = 2; $p = $i++; echo $i; ?>Output of above code is 3. Why this difference? I mean how these codes are processed to give an output? i have searched everywhere and no code seems to work. i have time1 and time 2 in the format Y-m-d H:i:s. i just don't know how to find the difference. old time: 2011-04-11 20:15:46 new time: 2011-04-11 21:00:11 after i have the difference, i need to get a resource production per hour which is stored in the database and calculate the new value of the resource. $production_per_hour = 100; $time_old = "2011-04-11 20:15:46"; $time_new = "2011-04-11 21:00:11"; $current_resources = "500"; For some reason when I echo $diff and $time_remaining it ALWAYS echos with values of 3 and 7 and not sure why. Code: [Select] $lock_date = $row['lock_date']; $current_time = time(); // Find out if user is locked out of their account if (($lock_date != "0000-00-00 00:00:00") && strtotime($lock_date) < $current_time) { $lock_date = strtotime($lock_date); $diff = $current_time - $lock_date; $diff = floor($diff/6000); // Take minutes and perform tasks if ($diff <= 10) { // Calculate time remaining $time_remaining = 10 - $diff; // Account locked error $errors = true; $message = "Account is locked! Must wait " .$time_remaining." minutes to log in again!"; $output = array('errorsExist' => $errors, 'message' => $message); } else { // Clear the lock $query = "UPDATE users_logins_attempts SET lockDate = NULL, ip_address = NULL, failed_logins = 0 WHERE users_id = '".$users_id."'"; $result = mysqli_query($dbc,$query); // Account locked error $errors = true; $message = "Account is unlocked. You may now try to log in again!"; $output = array('errorsExist' => $errors, 'message' => $message); } } Hi I'm trying to get this to work. I have known date in MySQL database entered as 2019-08-01 and I need to calculate from that date to current time. What I have is this code
$date_ts = strtotime($row['date_ts']); //Timestamp
$date_str = date("M-d-Y", $date_ts); //String in format MMM-DD-YYYY
$TotalTime = floor((time() - $date_ts)/(60*60*24)) . ' days';//Total in days
but my result showing as ==> 18367 days Could someone please help me get this to work so it shows the right number of days. thank you
Hi, Trying to figure out a way to get a time difference between two times assuming they are in order.. For example; in the array below the days is easy.. because the time happens later, however nights it becomes a little more confusing. The method I'm using now is; if the dates are in order just stick a reference date on there, and get a difference. If they seem to be reversed, I stick a reference date on the first one and a reference date +1 days on the second and get the difference.Can you all think of a better way? I will use the assumption that the times will NEVER be more than 24 hrs apart..
Array
(
[2] => Array
(
[days] => Array
(
[0] => 07:00:00
[1] => 15:45:00
)
[nights] => Array
(
[0] => 15:30:00
[1] => 02:15:00
)
)
What is difference between php date(); and mysql NOW() and what should be used in script? In php date I have 13:00h, and from MySql have 17:00h. Current date on my comp is 19:00h. So time difference in php is +6 hours, and in mysql is +2 hours. How to synchronize this dates for users??? hello, im trying to figure out the difference between 2 numbers in minutes. here is what i have: Code: [Select] $tsignin="09-05 10:30:00"; $tsignina="09-06 11:30:00"; $log_in_time_stringsa = strtotime($tsignin); $log_out_time_stringsa = strtotime($tsignina); $difference_in_secondssa = ($log_out_time_stringsa - $log_in_time_stringsa); $tsigna = ($difference_in_secondssa / 60); $tsigna2 = number_format(round($tsigna)); the 09-05 is sept 5, and 09-06 is sept 6. this works if the month and date are not included. any ideas for me so i can figure out the total difference between date/times? Hey guys, What i would like to create is the ability to calculate the difference between two dates / times. For example: 2010-12-13 10:00:00 to 2010-12-17 17:00:00 In a format of days / hours and minutes / seconds. However, I only want to calculate for an 9-5 work day, not the hours outside. Is this possible? If so, how would I go about creating something like this. |
