My arduino uno interfaced with rc522 can't connect talk to the php code that connects to the sql database

[shtoic]

i cannot obtain an ip address from my router that is responsible for connecting to the php code and connecting to the sql database (im using xampp and phpmyadmin)

it displays this in the serial moni:
0.0.0.0
CLEARDATA
LABEL,Date,Time,RFID UID,Name
Scan PICC to see UID...

this is my arduino sketch:

#include <SPI.h>
#include <MFRC522.h>
#include <Ethernet.h>

#define SS_PIN 10
#define RST_PIN 9
MFRC522 mfrc522(SS_PIN, RST_PIN);  // Create MFRC522 instance.

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // Ethernet shield MAC address

char server[] = "192.168.1.8";                                     // IP address Komputer
IPAddress ip(192,168,1,8);                                        // IP address Ethernet Shield
// the dns server ip
IPAddress dnServer(192, 168, 1, 1);
// the router's gateway address:
IPAddress gateway(192, 168, 1, 1);
// the subnet:
IPAddress subnet(255, 255, 255, 0);
EthernetClient client;

int buzz = 2;

  Ethernet.begin(mac, ip, dnServer, gateway, subnet);

    sendDataToServer(StrUID, name);
  }

  }

    return 0;
  }

  Serial.println("THE UID OF THE SCANNED CARD IS:");

  for (int i = 0; i < 4; i++) {
    readcard[i] = mfrc522.uid.uidByte[i]; // storing the UID of the tag in readcard
    array_to_string(readcard, 4, str);
    StrUID = str;
  }
  mfrc522.PICC_HaltA();
  return 1;
}

its for my capstone project i need your help guys thank youu
