[RESOLVED] CI framework gives error in xampp1.7.3

[eluser]suba[/eluser]
I put trailing slash on my base_url
still I got error.

When I execute my welcome page, browser displays content of model_sims file.
example: this content & statement has inside in model_sims file

Code:

function showKeyValue($type,$key)
// -----------------DON'T REMOVE THIS FUNCTION----------
{ $where=array('type'=>$type,'value'=>$key); $query=$this->db->get_where('information',$where);
foreach($query->result() as $row) { return $row->name; } $query->free_result(); }*/
function showKeyValue($type,$value)
{
$type=strtoupper($type);
switch($type) {
case "RACE": switch($value) {
case 1: return "MALAY"; break;
case 2: return "CHINESE"; break;
case 3: return "IND/PAK/SL"; default: return $value;
break; }
break;
case "CITIZENSHIP":
switch($value) {
case 1: return "SINGAPOREAN"; break;
case 2: return "SINGAPORE PR"; break;
case 3: return "ASIAN"; break;
case 4: return "NON-ASIAN"; break; }
break; }
}
function showSchoolName($key) {
$this->db->where('number',$key);
$query=$this->db->get('si_school_list');
foreach($query->result() as $row) { return $row->name; }
$query->free_result();
}

Then last line I got this error message.

Code:

Fatal error: Class 'Model_sims' not found in C:\xampp\htdocs\sims\system\libraries\Loader.php  on line 184.

But above two functions are inside in my model_sims file.
If model_sims does not load, how the browser displays the contents of the model_sims file.
how is possible.
please any one advice me.
