fopen con variabile

[giuseppe500]

ciao.
ho il seguente codice:

function getSelectModel($page){
    
    $arrModels = array();
    $file_handle = fopen($page, "r");
    $i=0;
    while (!feof($file_handle) ) {
    $line_of_text = fgets($file_handle);
    $parts = explode(';', $line_of_text);
    $arrModels[$i]=$parts[0];
    $i++;
    }
    fclose($file_handle);

    $strSelect="<select>";
    foreach($arrModels as $row)
    {
        $strSelect.="<option>".$row."</option>";    
    }
    $strSelect.="</select>";
    return $strSelect;
} 

se chiamo la funzione con :
getSelectModel('db.txt')
e db.txt esiste , verificato con tanto di permessi di scrittura.
ottengo questi warning:
