PHP - Subtract Time()-14 From Time() Output Not As Expected. What Am I Doing Wrong?
I am trying to simulate an ad expiration and carry out an action if the ad is expired. And I cannot get the if/else to work properly... I've tried many variations and I cannot see what I am doing wrong here. Any tips please 3 hours and counting of no solution!
$ad_start = time()-14 . "<br />"; // 14 days from today in the past (negative) echo $ad_start; $current_time = time() . "<br />"; // current epoch time echo $current_time; $days_past = $ad_start - $current_time; // days past echo "<br />$days_past days have past since the ad started!<br />"; if($days_past <= 14) { echo "<br />Ad is less than 14 days. Not expired."; } else { echo "<br />Ad is over 14 days. Expired."; } Similar TutorialsHey 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. I have this:
$sql = mysqli_query($conn, "SELECT ip
, page
, CASE WHEN referrer = ''
THEN 'N/A'
ELSE referrer
END as referrer
, DATE_FORMAT(date, '%m/%d/%y') as date
, TIME_FORMAT(time, '%T') as time
FROM tblTraffic
ORDER BY date DESC, time DESC");
most of my traffic report contains the correct times, my time, which is CST in the USA. but some records are off by a lot. Does the time() function capture the time of the actual location from which the visitor is coming from? if so, what could I do to return my timezone for any visitor? w3 schools and php.net don't mention this. Hello, I am trying to subtract the current time from a list of times in a mysql database. The first page inserts the time into mysql.
<?php
$var_Time = date("h:i:s");
$mysqli = new mysqli('localhost','root','blah','test');
if ($mysqli->connect_error) {
die('Error : ('. $mysqli->connect_errno .') '. $mysqli->connect_error);
}
$insert_row = $mysqli->query("REPLACE INTO test_table (id, time) Values(NULL, '$var_Time')");
if($insert_row){
while (false);
}else{
die('Error : ('. $mysqli->errno .') '. $mysqli->error);
}
$mysqli->close();
?>
The second page is supposed to iterate through all of the times in the database and subtract the current time, but i cant figure out how to do it.
<?php
$mysqli = new mysqli('localhost','root','blah','test');
if ($mysqli->connect_error) {
die('Error : ('. $mysqli->connect_errno .') '. $mysqli->connect_error);
}
$query = "SELECT * FROM `test_table`";
$result = $mysqli->query($query) or die($mysqli->error.__LINE__);
$var_set_time = stripslashes($row['time']);
$var_current_time = date("h:i:s");
$diff = strtotime( $var_current_time .' UTC' ) - strtotime( $var_set_time .' UTC');
echo $diff;
?>
Edited by Ch0cu3r, 09 October 2014 - 01:40 PM. Added code tags I have a loop that writes out data for franchises. It works the first time through, but not the 2nd. Here is the page where the data is written out: http://184.172.137.97/~royl21st/1.php Here is the code that spits out the wrong data after the first successful loop. Any ideas? Code: [Select] $areaCodeData = getData($sSql, $con, $dbName); $areaCodeRowCount = mySQL_num_rows($areaCodeData); $areaCodeRowCur = mysql_fetch_assoc($areaCodeData); if ($areaCodeRowCount != 0) { echo "<div class='box left'>"; // list all Area Codes for this Franchise echo "<div class='details'>"; $areaCodes = ""; for ( $ctrAreaCode = 0; $ctrAreaCode <= $areaCodeRowCount - 1; $ctrAreaCode += 1) { // grab AreaCodes $areaCodes = "<b>".$areaCodes.$areaCodeRowCur['AreaCode']."</b>, "; // fetch next AreaCode row $areaCodeRowCur = mysql_fetch_assoc($areaCodeData); } // end ctrAreaCode for loop $areaCodes = substr($areaCodes, 0, strlen($areaCodes)-2)."<br />"; echo "<em>-- Area Codes Supported:</em><br/>"; echo $areaCodes; echo "</div>"; echo "</div><br />"; } //end Area Code loop // reset AreaCode loop pointers (is this a PHP bug?) mysql_data_seek($areaCodeData,0); At this point I'm desperate and I have to get this working ASAP. The Grand Rapids, Kalamazoo, Holland area codes are 616, 269, 616 and their area codes are 49xxx Thanks in advance for the help... I'm working on a chat using basic textarea input, post, but the problem that I'm facing is, if a person doesn't send something, then the output is not updated eg. other messages from other users updating in real time.
How is that achieved when you see new database entries pop up live, milliseconds after they are entered?
Do I set a constant refresh rate of some sort?
How do you update a section of a webpage without "refreshing" the entire page like the POST method?
I think it is unusual but i dont know to fix it. when my computer clock shows 16: 13 hours , date() reuturns 10:43:16 . My systems time zone is +5.30 GMT. how does date() subtracts 5.30 hrs from the system time? First, I would like to say when i tried to recover my account from this website, I took me 10 attempts to get the captcha right and then finally it said it sent me an email to my gmail account. I checked spam folder and everything there was no such email from this site. Then I decided to create a new account, well, it took me another 10 attempts to get the captcha right and finally when it was submitted, the page was loading for around 3 minutes before it signed me in.
My question is about the php date() function. It accepts a format to display a time. In the following example I use F for full representation of month, d for 2-digit day of month with leading zeros, Y for full year, g for 12-hour format without leading 0s, s for seconds and A for meridiem. It uses the correct format, but it gives me the wrong time. My local time is 4:43 and it prints out 4:12:
<?php echo "<p>order processed on " . date("F d, Y g:sA") . "</p>"; ?> Why is it 30 minutes behind? 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
Expected Output
Server Time 21-05-21 10:55:39
Any help would be appreciated. Edited May 21 by Ponel Basically I have recently been playing around with parsing a csv file. What I am looking to do at this point is simply take the date/timestamp (part of the csv file), which is in the following format:DD/MM HH:MM:SS.100th/s For the sake of argument, lets say I have this in an array string called $csv[0] and the file has several lines that span the course of a couple hours. I wouldn't mind having to use explode() to breakup/remove the date or 100th/s IF that would make things a lot simpler. So where would I start in trying to achieve this?. The result I am looking for will simply return "X Seconds". Storing this in a string variable would be a bonus, as I plan to use this to divide a separate piece of information. Any examples or ideas would be great. Thank you. ps: Here is an example time from the csv file itself: Code: [Select] 11/19 22:23:18.143 This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=316461.0 I am having a problem with PHP displaying the correct date and time. It updates as it should, but is fast by 4min and is always displaying a date in 2004. I ran a basic php script to make sure the application im using itself is not wrong. go to lunenburgledger.com/time.php Anybody had any ideas on where to check? The system time on the Windows Server 2003 is correct. The only thing I can think of is that it was converted to a virtual machine on vmware esxi, but the system time stayed right. Any ideas? Thanks! PHP 5.2.6 We rent PHP server space on a server in California. Several of my pages generated by PHP show the current date and time, so when the page is printed, the user knows when the data was printed. Our users could be anywhere in the US, I am in Michigan. How do I convert the server time (PDT) into local time, regardless of where the user is? Thanks. OK So I've got a datepicker that sends a date in d/m/y format. My DB stores the data in Unix Timestamp Which I can convert the date to with strtotime however this does the exact date & time. All I want is the actual day. I've spent hours trying to convert this with just the day with mixed results... Thanks.
What are the differences and implications of UTC time and Zulu time?

Hello, I tried to implement some PHP code to enable a web page to show "Dinner" specials versus "Lunch" specials based on the time. The business is located in the Eastern Time Zone, so I only need to routine to work based on Eastern Time (New York). What I am noticing is that the server is processing the lines of code so fast that the command to establish the correct time for the remaining code is not always being acknowledged. This line of code appears to be processing too fast for the remaining lines of code: date_default_timezone_set ( "America/New_York" ); Is there some additional code I can put in place to make sure the correct time is always ascertained? I need the $hourmin variable to always return a combination of hour + minute based on 24-hour time and Eastern Time zone. My code is as follows: <?php $name8 = file_get_contents("test/special8name.txt"); date_default_timezone_set ( "America/New_York" ); $gethour = date("H"); $getminutes = $gettimedate["minutes"]; $gettimedate = date(); $hourmin = $gethour . $getminutes; $currentday = date("l", time()); $currentdate = date("M j, Y"); if ($hourmin < 1500 && $currentday <> "Saturday" && $currentday <> "Sunday") { echo "<span class=\"namesred\">$name8 </span>"; } else if ( $hourmin > 1500 && $hourmin < 2300 && $currentday <> "Saturday" && $currentday <> "Sunday") { echo "<span class=\"namesblue\">$name8 </span>"; } else if ( $currentday == "Saturday" or $currentday == "Sunday") { echo "<span class=\"namesblue\">$name8 </span>"; } ?> I am making a time clock, and I was wondering what is the best way to calculate the number of hours an employee worked? I have a table called "statuses" it holds names of punch types: - id = the auto_inc - status = "in/out/break/lunch" text statuses - paid = whether or not the punch is paid or not (true/false) I have another table called "logging" This table holds the information about the punch type: - id = the auto_inc - owner = the member id - ip = members ip - inout = the punch type from the statuses table - location = the city/state of where the punch took place - date = the time the member punched Maybe I am over thinking this, but what is the best way to calculate the hours a person has worked? Right now I am getting all the punches for for a particular member between a date range. then loop through the data to display it and passing it to a method in a class called Calc. I want to then add the times from punch in to punch out, then the next punch in to punch out. Any suggestions? Let's say I am buying a share for $10. If I sell the share on the same day BEFORE 3:30PM, it will be sold for $10, but if I keep the share past 3:30PM, I want the code to automatically add $1 (Taxes and such) once in the the price of the share in database, after that no matter how many days pass by, the price will remain the same.
I've thought about CRON jobs, but I have no idea how to make/use them or set them up.
Any direction or help is appreciated.
Hi, The hosting provider for my domain confirm me that the server time is in EST (UTC-5). They also sent me a grab supporting that Code: [Select] server time is now: ---------------------- Sun Nov 7 02:20:01 EST 2010 ------------------- But when I use the following code, the output I get is has 1 hr difference (UTC-6) echo date("d M, Y h:i:s A",time()); Output==> 07 Nov, 2010 01:20:01 AM But it suppose to give the same time as the server, ryt? Can anybody please explain? Thanks, Hey Guys! I have the following doubt. When echoing from Server like this: Code: [Select] echo "time=" . time(); I get the time in the following raw format: 1299272294 I would really like to echo it with this format: Tue Mar 1 23:50:00 GMT-0300 2011 Is there a way I could do that? Really looking forward for some help on this one, Thanks a lot in advance! Cheers! Here is my function which almost works as expected: <?php function find_value($array,$value) { for($i=1;$i<sizeof($array);$i++) { if($array[$i] == $value) { echo "$i . $array[$i]<br />"; return; } } } ?> And I call the function like so: <?php $names = array('Jason','Mike','Joe'); $name = 'Joe'; find_value($names,$name); ?> And the output is: 2 . Joe According to my understanding of Arrays, Joe would be index 3 BECAUSE my counter starts at 1 in my for loop??? Why is the result like this? What am I not understanding here? |
