Project with Arduino + Modulo Ethernet ENC28J60

I developed a code that counts the number of people passing in front of the infrared sensors.

But I wanted the arduino was a client and the FTP server consume these values. But I do not know php, but it would be something like this. The server is localhost.

#include <UIPEthernet.h>

EthernetServer server = EthernetServer(80);

int sensor1 = 8;
int sensor2 = 9;
unsigned long timeS1 = 0, timeS2 = 0;
unsigned long dif;
int nPessoas = 40;

void setup() {
    pinMode(sensor1, INPUT);
    pinMode(sensor2, INPUT);

    Serial.begin(9600);

    uint8_t mac[6] = {0x00,0x01,0x02,0x03,0x04,0x05};
    IPAddress myIP(192,168,0,105);
    Ethernet.begin(mac,myIP);
    server.begin();
}

void loop() {
    if (!digitalRead(sensor1)) {
        timeS1 = millis(); 
    }
    if (!digitalRead(sensor2)) {
        timeS2 = millis(); 
    }

    dif = timeS2 - timeS1;

    dif = timeS2 - timeS1;
    if(dif >= 500 && dif <= 1500){
       timeS1 = timeS2 = 0;
       nPessoas++;
   }

    size_t size;

    if (EthernetClient client = server.available()) {
        while((size = client.available()) > 0) {
            uint8_t* msg = (uint8_t*)malloc(size);
            size = client.read(msg,size);
            Serial.write(msg,size);
            free(msg);
        }
            String data = "contador=" + String(nPessoas);        
        if (client.connect("http://192.168.0.101",80)) {
            client.println("POST /test.php HTTP/1.1");
            client.println("Host:  192.168.0.101");
            client.println("User-Agent: Arduino/1.6");
            client.println("Connection: close");
            client.println("Content-Type: application/x-www-form-urlencoded;");
            client.print("Content-Length: ");
            client.println(data.length());
            client.println();
            client.println(data);

      } else{
            client.println("Erro de conexao...");
  }
        if (client.connected()) {   
            client.stop();  
        }
    }      
    delay(10);
}

file.php

<?php
      $value = ($_REQUEST['contador']);     
      echo $value;
?>

OUTPUT

Is there a question?

Yes. it’s a question.

OK, Thanks for the clarification.
