Do not pass the parameters to the URL with arduino + ethernet

Good evening guys, I'm trying to give an INSERT in a mysql database with parameters that I pass through arduino via GET to a php page with the name of salvardados.php I can not think of a solution to that. Because in my view it is right, but it does not insert from any forna

#include <SPI.h>
#include <Ethernet.h>


byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

byte ip[] = { 192, 168, 0, 105 };

byte servidor[] = { 192, 168, 0, 103 };

EthernetClient cliente;

float sensor1 = 0;
float sensor2 = 0;
float sensor3 = 0;

void setup() {

  Serial.begin(9600);
  Ethernet.begin(mac, ip);

}

void loop() {
  char comando = Serial.read();
  if (comando == 'a') {
    if (cliente.connect(servidor, 9080)) {
      Serial.println("conectado");

      sensor1 = sensor3 + 5;
      sensor2 = sensor1 + 5;
      sensor3 = sensor2 + 5;

      cliente.print("GET /arduino/salvardados.php?");
      cliente.print("sensor1=");
      cliente.print(sensor1);
      cliente.print("&sensor2=");
      cliente.print(sensor2);
      cliente.print("&sensor3=");
      cliente.println(sensor3);

      Serial.print("GET /arduino/salvardados.php?");
      Serial.print("sensor1=");
      Serial.print(sensor1);
      Serial.print("&sensor2=");
      Serial.print(sensor2);
      Serial.print("&sensor3=");
      Serial.println(sensor3);



      cliente.stop();

    } else {
      Serial.println("falha na conexao");
    }
  }
}

php:     include_once ("connection.php");

$sensor1 = $_GET['sensor1'];
$sensor2 = $_GET['sensor2'];
$sensor3 = $_GET['sensor3'];

$sql = "INSERT INTO tabelaarduino (sensor1, sensor2, sensor3) VALUES('$sensor1','$sensor2','$sensor3')";

mysqli_query($conectar, $sql);

echo $sql;
