[SOLVED] Array issues....

[maliary]

 

Hi guys,

 

It seems array issues just never end.

 

I have this while loop below which displays data from a  table. These are elements with this array

$tp['name']

Inside the while loop is a counter variable which increments at every loop.  This is used to display the elements from the $rval array.

 

$rval array values have this '-' (hyphen). There is an if statement to remove these array elements, which it does apart from the very first array value $rval [0]. It never get removed. Why???

 

$tests = $db->Execute("SELECT * FROM care_test_param WHERE  group_id ='$param_gp'"); 
    while($tp = $tests->FetchRow()){ 
                      
            
       if ($rval[$counterup] != '-') 
{    
       
           
           
    <tr class=';  if($toggle) { $cache .= '"wardlistrow1"';}else { $cache .= '"wardlistrow2"';}
    >
   <td> echo '.$tp['name'].' </td>'."\n"
   <td> echo '.$tp['msr_unit'].'  </td>'."\n"
   <td> echo '.$tp['lo_bound'].'</td>'."\n"
   <td> echo '.$rval[$counterup].' </td>'."\n"            
    </tr>
    $toggle=!$toggle;  
    
    
    
    
     } 
           
     $counterup++;     
    }

I changed the first value of the array $rval to 2 ,previously it was -. Then I changed the if statement to

if ($rval != 2) and it worked fine.

 

Is there a problem of if statements and strings?
