upload a value on a db in local web server

Using Arduino Programming Questions
#1

Hello,i’m sorry since now for my bad english,i need to load my temperature value in a db that are located in a local web server,i’ve done the php page and it work(i’ve tried with GET method and it works),but i can’t connect with arduino to this page,i’ve taken a arduino sketch on internet (i’ve modified a little this sketch because i have another sensor than it but i’ve tried the library of this sketch in another file and it works)but i think that i make a mistake when i select the ip,i thought ip server is the my pc ip but it seems do not work. i use Easyphp,thank you in advance for your help.
this is the sketch that i’ve found

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

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
//indirizzo server web (locale)
IPAddress server(192, 168, 1, 106);

//indirizzo ip dell'Arduino
IPAddress ip(192, 168, 1, 200);

//definizione pin arduino per sensore temp ecc
#define DHTPIN 8
// 8 è il pin di Arduino a cui collego il sensore di temperatura
#define DHTTYPE DHT11
// dht11 è il tipo di sensore che uso
DHT dht(DHTPIN, DHTTYPE);

EthernetClient client;

String strURL = "";
float temp = 0;

void setup()
{
    Serial.begin(9600);

    if (Ethernet.begin(mac) == 0) {
        Serial.println("Configurazione DHCP fallita!");
        Ethernet.begin(mac, ip);
    }

    delay(1000);
}

void loop()
{
    UpdateTemp();

    while (client.available()) {
        char c = client.read();
        Serial.print(c);
    }

    if (!client.connected()) {
        Serial.println();
        Serial.println("Disconnesso.");
        client.stop();
    }

    //esegui la richiesta ogni 10 secondi
    delay(10000);
}

void UpdateTemp()
{
    Serial.println("Connessione...");

    if (client.connect(server, 80)) {
        Serial.println("Connesso");
        //acquisisco il valore analogico dal sensore DHT11
        temp = dht.readTemperature(); //leggo temperatura da sensore

        //creo l'url utilizzanso una stringa
        strURL = "GET /arduino/RaccogliementoDati.php?valore="; //devo modificare nome pagina
        strURL += (int)temp;
        strURL += "&localita=Sardegna HTTP/1.1"; //Inserisco località che più mi piace

        //invio la richiesta al server
        client.println(strURL);
        client.println("Host: localhost");
        client.println("Connection: close");
        client.println();
        //chiudo la connessione
        client.stop();
    }
    else {
        Serial.println("Errore Connessione");
    }
}
#2 
        client.println("Host: localhost");

That is NOT the correct host.

Do you KNOW what localhost means? If so, you'd KNOW that the name is the wrong name to use there.

        //chiudo la connessione
        client.stop();

Once you've told the server to dump whatever it was going to return, there is no point, in loop(), in trying to read the server response.

Thanks for the help,i try and i say the results
