PHP
1

Hello every body
Please help me to write this code
i want to display table like this

Generated from three database tables depends on student ID

[URL=“http://img51.imageshack.us/img51/1272/tablesh.jpg”]http://img51.imageshack.us/img51/1272/tablesh.jpg

So i want to display this table without any fixed value of exams or subjects … just i want the idea of looping

And is this the best way to insert the students marks?? coz by this way if i have 5000 student and 10 subjects and 12 exam in year … i will have mor than 500.000 record in table Stu_Marks

sorry for my english language

Welcome to the SP forums.
If you post the code you have so far, and then ask a specific question about something that is blocking you, then I’m sure someone will be willing to point you in the right direction.

And is this the best way to insert the students marks?? coz by this way if i have 5000 student and 10 subjects and 12 exam in year … i will have mor than 500.000 record in table Stu_Marks

Yes that’s the best way. You don’t have to worry about performance if you create the right indexes.

<?


$con = mysql_connect("localhost","root","123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("test", $con);


////////////////////////


	
	///////////////// Select the exams and put it in array
	$ex = mysql_query("SELECT * FROM exams");
	$dc=1;
while ($rowex= mysql_fetch_array($ex)){
	$exn[$dc]=$rowex['Exam_Title'];
	$exid[$dc]=$rowex['Exam_ID'];
$dc++;
	}
	
	
	/////////////////////////// Select the subjects and put it in array
	$sj = mysql_query("SELECT * FROM subjects");
	$dsj=1;
while ($rowsj= mysql_fetch_array($sj)){
	$sjn[$dsj]=$rowsj['Subj_Title'];
$sjid[$dsj]=$rowsj['Subj_ID'];
$dsj++;
	}
	
	///////////////////Select the student marks and put it in array with subject id and exam id
	
	$result = mysql_query("SELECT * FROM stu_grade");
while ($row= mysql_fetch_array($result)){
	$arr[$row['Subj_ID']][$row['Exam_ID']]=$row['Grade'];

	}
	/////////////////////// count the exams and the subjects to draw the table
	 $exc=count($exn);
	 $sjc=count($sjn);
	 ?>

<table width="400" border="1">
  <tr>



     <?
///////// display subjects in table rows
for ($d=0;$d<=$sjc;$d++){
	
	if ($d==0){
	echo '<td>-</td>';
	}else{
	echo ' <tr><td>'.$sjn[$d].'</td>';
	}
///////// display exams in table head tds

for ($p=1;$p<=$exc;$p++){
	if ($d==0){
	echo '<td> '.$exn[$p].'</td>';
	}else{
?>
 <td>

 <?=$arr[$sjid[$d]][$exid[$p]]?>

 </td>
      <?}
      }
}?>

Hi,

Why don’t you know if this is correct or not? Have you ran it? Do you get any errors? Are you asking just if this is a good way to do this?
