PHP - Clients Browser's Tab Closed During Run Time
I made a bug which caused endless loop and endless printing.
When I noticed that, I closed the browsers tab, fixed the bug, open a new tab and re-run. I was assuming the server would start from the beginning, but instead I noticed that some variables were active and the program continued from where it stopped. How can I make the program to stop when the client tab is terminated? Similar TutorialsOK, I'm nearing the end of a very long chat project and I have one last hurdle to jump, I've saved this task to the near end because I thought it would be a problem as I have no idea what to do or where to start. The problem is exactly what is said in the subject title. I have looked into JavaScript options such as "onbeforeunload" but that is just BAD. The login is controlled by sessions, so when the user closes the browser, the session is ended, but data in the database says different, cookies are not an option I'm afraid. I've had an idea that if I create a special account (or a few) and always leave these accounts logged in, they can check if a user has been inactive for a certain period of time, and then run queries to change things, I know this sound odd but maybe I will not have to create these accounts but general accounts that people make will be able to do this for me, without them even knowing. Please help, any ideas, suggestions, logic or methods that you think will help will be great. Thanks. Hey All, I have a sessions table that is used to see if a user is online. It only gets deleted when they click the Logout button. What I need to do is have it so it gets deleted even if they close the browser. Should I add a column in the sessions table with a time stamp and check on each page for every user to make sure its great than 30 min? Is there a better way to do this, without so many queries? Thanks Hello, How do I get a user's session destroyed when he closes his browser?

I log the hostname of the computers when they do certain things in our Intranet. When the hostname is logged, certain clients are getting both the hostname and the localhost IP address added. For example, if the PC name is TOMS-PC, the hostname logged is TOMS-PC172.0.0.1 Other clients are logging just the hostname as it should be. All I use to grab the hostname is: Code: [Select] $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']); Any clues as to what causes this? Hello dear friends, let say we have (function) and that function has one variable which is (id) the (id) could be number any number 1 or 4 or even 49999 whatever. how to make closed loop which i mean run this function in unlimited way each time with new id <--- i can do it by set random() but the problem i've is how to make it repeat itself excuted excuted excuted | | | ect let say for example , i will insert random number in at database table Code: [Select] $id = rand(); mysql_query("INSERT INTO comments(id) VALUES ('$id')"); that is it, how then i can repeat it many many times without 1) refresh 2) rewrite it many times thanks in advance Here is one of my emails.

Hi Everyone, I wonder if somebody could help me. I have been at this for hours and am really struggling. I have a timer which I have set up for a quiz. The quiz opens in a javascript shadow box. When the quiz is opened a session variable for the timer is set up to keep track of the time. What I need is for this session variable to end when the shadow box is closed. I have a onClose hook to peform actions when the shadow box is closed which is in javascript. Obviously I cannot end the session variable in the javascript function due to js being client side and php being server side. Has anyone any suggestions how I can resolve this issue. I need to end this session variable as if the user exits the quiz and then selects another quiz to do the timer uses the current time session rather than assigning the new time value for that particular quiz. Thanks in advance. Edd Ok this is some noob question here I have a page that has few separate pieces of php code embeded within html code. Each piece is separated with Code: [Select] <?php ... ?> tags, everything works fine. I need to assign a variable in first (from the top) piece of php code. Then I want to be able to use that variable in all others php pieces across this same page.... I searched and searched and first tried to do it like : First piece: Code: [Select] <?php function id() { $id="blah"; } ?> Second piece : Code: [Select] <?php id(); ... echo $id; ?> didn't work, then I tried First place: Code: [Select] <?php $id="blah"; function id() { global $id; } ?> Second piece : Code: [Select] <?php echo $id; ?> After struggling and reading for few days all about global, static, and regular variables i finally decided to ask professionals to help.... please let me know if you need me to make the question description more clear or smn i have a script that wrote which updates fields in a mysql database with millions of rows. it just uses a while loop for each row. now the problem is that i forgot to add something to the script, but i already visited the .php file in my browser. i closed the browser and when i refresh the database it still seems to be running even though i closed the browser the script was running on.... is this because the script is still cached in the memory or what? how can i stop it? I GET QuoteFatal error: TPL: [in line 0]: syntax error: file 'm/pg/_categories' does not exist in C:\WebServ\httpd\libs\tpl\class.template.php on line 943 unset($_templatelite_tpl_vars); else: $_templatelite_tpl_vars = $this->_vars; echo $this->_fetch_compile_include($this->_vars['TPLx'].'m/pg/_categories'.$this->_vars['HTML'], array()); $this->_vars = $_templatelite_tpl_vars; WITH FILES http://testynarkotykowe.j13x.pl/index.txt && http://testynarkotykowe.j13x.pl/indexpg.txt HOW TO FIX IT 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") .

Edited May 21 by Ponel Hello all, I'm an amateur at PHP coding, and am currently enrolled in a PHP and MySQL class that uses the PHP Programming with MySQL textbook, by Don Gosselin. I'm trying to get this simple Shopping Cart script to work, because it's the step-by-step example script for Chapter 11, but I keep getting the following errors on ShowCart.php when I try to add an item to the cart.

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
What are the differences and implications of UTC time and Zulu time?
<?php
function getArr(string $time):array
{
$dateTime = new \DateTime($time);
return [
'time'=>$time,
'timestamp'=> $dateTime->getTimestamp(),
'dateTime' => $dateTime
];
}
$arr = getArr('2020-08-05');
$arr_z = getArr('2020-08-05T00:00:00Z');
print_r($arr);
print_r($arr_z);
echo('equal timestamps: '.($arr['timestamp'] === $arr['timestamp']?'true':'false'));
Array
(
[time] => 2020-08-05
[timestamp] => 1596585600
[dateTime] => DateTime Object
(
[date] => 2020-08-05 00:00:00.000000
[timezone_type] => 3
[timezone] => UTC
)
)

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. |
