会话变量与数组

i want to use session variable in the code. my requirement is that when i click on "edit/Delete" button,record against the correspondence row is deleted automatically. can any one plz help me how to resolve this problem and also tell me how to use session variable.

`<?php
while($row = $result->fetch_array())
print("
<tr>
<td> $row[0] </td>
<td> $row[1] </td>
<td> $row[2] </td>
<td> $row[3] </td>
<td> $row[4] </td>
<td> <a href='dscm-Emp-Modification.php?ID= $row[0]'>Edit</a></td>
<td> <a href='dscm-Emp-Delete.php?DID= $row[0]'>Delete</a></td>
</tr>
");
?>`

i tried following codes but neither of them worked for me:

//method 1

while($row = $result->fetch_array())

$_SESSION['a']=$row[0];
$_SESSION['b']=$row[1];
$_SESSION['c']=$row[2];
$_SESSION['d']=$row[3];
$_SESSION['e']=$row[4];
print("
<tr>
 <td> $_SESSION[a] </td>
 <td> $_SESSION[b] </td>
 <td> $_SESSION[c] </td>
 <td> $_SESSION[d]</td>
<td> $_SESSION[e]</td>
<td> <a href='dscm-Emp-Modification.php?ID= $row[0]'>Edit</a></td>
<td> <a href='dscm-Emp-Delete.php?DID= $row[0]'>Delete</a></td>
</tr>
");

//method 2

{
for ($a=0; $a<=4; $a++){
$_SESSION['data']=$row;
print("
<tr>
    <td> $_SESSION[data] </td>
    <td> $_SESSION[data] </td>
    <td> $_SESSION[data] </td>
    <td> $_SESSION[data] </td>
    <td> $_SESSION[data] </td>
    <td> <a href='dscm-Emp-Modification.php?ID= $row[0]'>Edit</a></td>
    <td> <a href='dscm-Emp-Delete.php?DID= $row[0]'>Delete</a></td>
  </tr>
");
}
}

You need to call the session_start() function befor use the $_SESSION-Array.

Please read more about sessions in the PHP documentation here.
