you'll need javascript trick, see snippet:
function hl(ob){ if(ob.checked == true){ ob.parentnode.parentnode.style.backgroundcolor='red'; } if(ob.checked != true){ ob.parentnode.parentnode.style.backgroundcolor='white'; } }<table border=1 cellspacing=0 cellpadding=5> <tr> <td><input type="checkbox" name="checkbox" value="1" onclick="hl(this)" /></td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> </tr> <tr> <td><input type="checkbox" name="checkbox" value="2" onclick="hl(this)" /></td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> </tr> <tr> <td><input type="checkbox" name="checkbox" value="3" onclick="hl(this)" /></td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> </tr> </table>edit
<html> <head> <title>db testing</title> <script type="text/javascript"> function hl(ob){ if(ob.checked == true){ ob.parentnode.parentnode.style.backgroundcolor='red'; } if(ob.checked != true){ ob.parentnode.parentnode.style.backgroundcolor='white'; } } </script> <style> table{ font-family: arial, sans-serif; border-collapse: collapse; width: 80%; } td, th { border: 1px solid #dddddd; text-align: left; padding: 8px; } </style> </head> <body> <?php //db2 express c (v10.5) in local $database = "db"; $user = "user"; $password = "password"; //create connection $conn = db2_connect($database, $user, $password); //check connection if($conn) { //echo "db2 connection succeeded.<br><br>"; } else{ exit("failed".db2_conn_errormsg()); } //select fields database $sql = "select 'junk', a, b, start_time, end_time, start_day, end_day, c, id, business_area, environment testtable a='d' , availability = 'y'"; $stmt = db2_prepare($conn, $sql); //db2_execute executes sql statement prepared db2_prepare if($stmt){ $result = db2_execute($stmt); if(!$result){ echo "exec errormsg: " .db2_stmt_errormsg($stmt); } //the echos below output data in html table echo '<table border = 1>'; echo '<thead>'; echo '<tr>'; echo'<th></th>'; echo'<th>a</th>'; echo'<th>b</th>'; echo'<th>start_time</th>'; echo'<th>end_time</th>'; echo'<th>start_day</th>'; echo'<th>end_day</th>'; echo'<th>c</th>'; echo'<th>id</th>'; echo'<th>business_area</th>'; echo'<th>environment</th>'; echo '</tr>'; echo '</thead>'; echo '<tbody>'; while($row = db2_fetch_assoc($stmt)) { echo '<tr>'; echo "<td><input name=\"checkbox[]\" type=\"checkbox\" value=\"".$rows[''].
