PHP - Difference Between Bar & &bar

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?

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 -

Thank you in advance. Any help would be greatly appreciated.

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 ?

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.

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);
                           
                        }
                       
                    }

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 ( $diff === 0 ) 
  echo "Today"
elseif ($diff > 0)
  echo "+" . $diff . "Days";
else 
  echo "LATE -" . $diff . "Days";

Something like that. Here is my code...

		//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 = '';

 

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";

<?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?

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,

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.

Front end web developer and a application developer?    is one better than the other?   also is getting a 1 year certificate in one of the above with lots of experience in relation to designing and coding land someone a job in this field?   Is a degree nessesary right now? in order to get a job in one one of these fields or  can one do that part time wile working but holding a certificate in one of these fields with freelance experience    

Hmm, not quite sure how to do this one...

If i have lots of strings saved in a mysql table and one was...
"A man and a dog took a nice walk in the park"

If a user then wanted to input another string into the table, but i wanted to check the new string was at least 5% different to all other in the table, how would i about doing this?

Is it possible to do this via mysql, or would i have to pull out all the strings into a php array and process it that way... somehow?

What is the difference between writing

if ($_POST['something'] == "" ) echo "that";
and
if ($_POST[something] == "" ) echo "that";

and would it have any effects?

What's the difference between str_split()  and chunk_split()? They seem to perform the same task?

try to give difference in points
