PHP - Can't Echo In Real Time Under A Foreach Loop

my output is this below:

Course: INFO101 - Bsc Information Communication Technology Course Mark:



Course: INFO101 - Bsc Information Communication Technology Course Mark:


Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B

Session: AAB Session Mark: 72 Session Weight Contribution 20%

Session: AAE Session Mark: 67 Session Weight Contribution 40%

Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B

Session: AAD Session Mark: 61 Session Weight Contribution 50%

As it shows 2 different Modules, it shows the "Course" details twice, I only want the "Course" details appear once as you can see both course details are the same.

How can I display the "Course" Details only once in the foreach loop.

To display the "Course" details I use this code: echo Code: [Select]
`"<p><br><strong>Course:</strong> {$courseId} - {$courseName} <strong>Course Mark:</strong></p><br>\n";`

Below is the code for the function and foreach loop:


Code: [Select]
     function outputModule($courseId, $courseName, $moduleId, $moduleName, $sessionData)
        {
       
            if(!count($sessionData))
            {
                return false;
            }
       
            $markTotal = 0;
            $markGrade = 0;
            $weightSession = 0;
            $courseTotal = 0;
            $grade = "";
            $sessionsHTML = "";
           
            foreach($sessionData as $session)
            {
       
                $sessionsHTML .= "<p><strong>Session:</strong> {$session['SessionId']} <strong>Session Mark:</strong> {$session['Mark']}</strong> <strong>Session Weight Contribution</strong> {$session['SessionWeight']}%</p>\n";
               
                $markTotal += round($session['Mark'] / 100 * $session['SessionWeight']);
                $weightSession  += ($session['SessionWeight']);
                $markGrade = round($markTotal /  $weightSession * 100);
                     
                if ($markGrade >= 70)
                {
                    $grade = "A";
                }
       
                else if ($markGrade >= 60 && $markGrade <= 69)
                {
                    $grade = "B";
                }
       
                else if ($markGrade >= 50 && $markGrade <= 59)
                {
                    $grade = "C";
                }
       
                else if ($markGrade >= 40 && $markGrade <= 49)
                {
                    $grade = "D";
                }
       
                else if ($markGrade >= 30 && $markGrade <= 39)
                {
                    $grade = "E";
                }
       
                else if ($markGrade >= 0 && $markGrade <= 29)
                {
                    $grade = "F";
                }
        }
       
            echo "<p><br><strong>Course:</strong> {$courseId} - {$courseName} <strong>Course Mark:</strong></p><br>\n";
            $moduleHTML = "<p><strong>Module:</strong> {$moduleId} - {$moduleName} <strong>Module Mark:</strong> {$markTotal} <strong>Mark Percentage:</strong> {$markGrade} <strong>Grade:</strong> {$grade} </p>\n";
       
            return $moduleHTML . $sessionsHTML;
        }

Ok so I have a question. is it possible to make a form submit to a DB in real time without the need for a submit button ?  if so could you drop a hint to what it would be caled or a tut / reference to it ?

Hi guys, got some questions about the Instagram real-time api. first let me tell you what I want to do. I'd like to run a daemon process with a socket connection or something of the like to the Instagram API to get a constant feed of photos with a certain tag. We estimate it to be a large amount of data at a particular time (thus why we want to go Real-time). This process will parse the feed and store it into a mongodb database.

Secondly, for the front end, I'd like to display all new, live photos in real-time, possible with ajax or some form of checking on a set interval.

Problem being, I can't find anyone doing this with php. All of the resources I have seen use Node.js and Tornado. Has anyone done this with PHP or know of a good Real-time API demonstration/tutorial to get me started?

Here's the documentation... http://instagr.am/developer/realtime/

any help would be greatly appreciated! thanks!

Below is my output on the browser:

    Student: Kevin Smith (u0867587)
    Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
    Year: 3
   
   
    Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B
   
    Session: AAB Session Mark: 72 Session Weight Contribution 20%
   
    Session: AAE Session Mark: 67 Session Weight Contribution 40%


    Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B
   
    Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.
   
    Below is the code:

Code: [Select]
    $sessionMark = 0;
    $sessionWeight = 0;
    $courseMark = 0;
   
    $output = "";
   
    $studentId = false;
    $courseId  = false;
    $moduleId  = false;
   
    while ($row = mysql_fetch_array($result))
    {
   
   
    $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
    $sessionWeight  += ($row['SessionWeight']);
        $courseMark = ($sessionMark /  $sessionWeight * 100);
   
          if($studentId != $row['StudentUsername'])
        {
   
            //Student has changed
            $studentId = $row['StudentUsername'];
   
            $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";
   
        }
             
        if($courseId != $row['CourseId'])
        {
   
            //Course has changed
            $courseId = $row['CourseId'];
   
            $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']}</p>\n";
   
        }
   
        if($moduleId != $row['ModuleId'])
        {
   
            //Module has changed
            if(isset($sessionsAry)) //Don't run function for first record
            {
   
                //Get output for last module and sessions
                $output .= outputModule($moduleId, $moduleName, $sessionsAry);
            }
   
            //Reset sessions data array and Set values for new module
   
            $sessionsAry = array();
            $moduleId    = $row['ModuleId'];
            $moduleName  = $row['ModuleName'];
        }
             
        //Add session data to array for current module
             
        $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);
             
    }    //Get output for last module
   
    $output .= outputModule($moduleId, $moduleName, $sessionsAry);
   
    //Display the output
    echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

Hi, i am thinking of creating a text based game mmorpg using php/mysql etc... I know that a lot of these types of games use a tick based system, but i want it to be realtime, the only game i cna find that uses this is Torn, does anyone know how they make it realtime? I know that ticks can be controlled by cronjobs, but how about realtime?

The problem is that the game might involve the player building a house, in a tick based system it could be easy to manage by saying the house will take 3 ticks to complete, but i want the house to be like in 10 minutes of 32 minutes, how can i do this. Someone said to check whenever the player next logs in to check if the house has finished and then say it has been built, but seeing as it is an mmorpg it could affect everyones gameplay, not just the person building it, so this will not work.

Thanks and sorry if this is a bit confusing.
