PHP - Script Wont Stop Despite Being Closed

Is there a way or function that stops the execution of a required script but continues to execute the parent script, for example:

if this is a.php

<?php
echo "<br>Good morning";

// function to stop execution of only this script to appear here

echo "<br>Good Afternoon";
?>

and then this is b.php

<?php

require("a.php');

echo "<br>Good Evening";
?>

So if the file b.php is called it is supposed to display:

Good morning
Good evening

So it has to skip "Good afternoon" because of the anonymous function which I need

My login script wont take my users to the restricted page and im not quite sure why it must be the header because it echos"wrong username or password" when i put in the wrong username or password here is my code:


if($count==1 & $row['flight']=="vulcan"){
session_start(vmyusername); 
session_start(vmypassword);  
header("location:/vulcan/index.php");
}else if($count==1 & $row['flight']=="valiant"){
session_start(myusernamev); 
session_start(mypasswordv);  
header("location:valiant/index.php");
}else
{
echo "Wrong Username or Password";
}
}
?>


Any help would be much appriciated

Thanks,

Hello dear friends,

OK, 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.

I have a class I use to handle my various DB objects.  I want to close any connections, if needed, in my destructor.  I want to do this even though I already know the connection has been closed previously.  What I am looking for is a way to test the $connection variable I have to see if it's in need of closing.  I can't figure out how to do this.


if (isset($this->connection))
{
    echo "is set";
}
   
if ($this->connection)
{
    echo "here";
}


The above would output "is set" and "here", because in both tests say the already closed connection is still there.  Can anyone offer any help?

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

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

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.

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?

Hello,
How do I get a user's session destroyed when he closes his browser?

Thanks in advance

HOW TO FIX IT

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. Quote

Warning: mysqli_query() [function.mysqli-query]: Couldn't fetch mysqli in C:\xampplite\htdocs\ShoppingCart.php  on line 78

Warning: mysqli_errno() [function.mysqli-errno]: Couldn't fetch mysqli in C:\xampplite\htdocs\ShoppingCart.php on line 80

Warning: mysqli_error() [function.mysqli-error]: Couldn't fetch mysqli in C:\xampplite\htdocs\ShoppingCart.php on line 81


Line 78:        $QueryResult = mysqli_query($this->DBConnect, $SQLstring)

Line 80 and 81:             . "<p>Error code " . mysqli_errno($this->DBConnect)
            . ": " . mysqli_error($this->DBConnect)) . "</p>";

I've read "Couldn't fetch mysqli" errors are because the connection was closed prior to those lines, but I don't see any indication of a connection closure. I have no idea what to do, as all the code was given to me in the book, I merely copied it down.

Here's the ShoppingCart.php code:<?php
