Error in function to list user data

Question

I’m having the error below when listing a user’s data by function lista().

Parse error: syntax error, Unexpected 'name' (T_STRING) in /home/adelanmu/public_html/usuario-class.php on line 54

public function lista(){
   $pdo = Conexao::conexao();
   $sql  = 'SELECT * FROM usuario WHERE id_cliente = ' . 
   $_SESSION['id_cliente'];';
   $consulta = $pdo->query($sql);
   $dados = null;
   while ($linha = $consulta->fetch(PDO::FETCH_ASSOC)){
       $dados[] = array(
         "nome" => $linha['nome'],
         "email" => $linha['email'],        
         "senha" => $linha['senha']          
       );     
   }
   $pdo = null;
   return $dados;
}
