Forbidden 403 nodemcu Apache

hi im using nodemcu trying to connect to mysql data base but i have 400 bad request
please help:

#include <ESP8266WiFi.h>

const char* ssid     = "****";
const char* password = "****";
const char* host = "192.168.0.112";
const unsigned int SENSOR_PIN = A0;
String strURL = "";
void setup()
{
  Serial.begin(115200);
  delay(10);

  // We start by connecting to a WiFi network

  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");  
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
 int sensor = analogRead(SENSOR_PIN);
  //String sensor = String(sensor);

    WiFiClient client; 
  if (client.connect(host, 80)) {
 
    Serial.println("connected");

strURL = "GET /connect.php?sensor=";
strURL += (int)sensor;
strURL += " HTTP/1.1\r\n";
client.println(strURL);
client.println("Host: localhost\r\n");
client.print("Connection: close\r\n\r\n");

client.println();
  }
    else {
    Serial.println("–> connection failed/n");
  }
  delay(50000);
  
   if (client.available()) {
     char c = client.read();    
     Serial.print(c);
   }

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
     Serial.println();
     Serial.println("disconnecting.");
     client.stop();

     for(;;)     ;  
   }
}

PHP Code:

<?php 
$servername = "localhost"; 
$username = "root";  
$password = "";

//$sensor = $_GET["sensor"]; 
$conn = mysql_connect($servername, $username, $password);
if ($conn) {
    echo "Connected successfully";
} 
else {
    echo "connection failed";
}

$conndb = mysql_select_db('coe', $conn);

echo  "<br>";

//$sql_insert ="insert into pulses (sensor) values ('$sensor')";
$sql_insert ="insert into pulses (sensor) values ('".$_GET["sensor"]."')";

if($sql_insert){
    echo "insert successfull";
}
else {
    echo "insert failed";
}

$result = mysql_query($sql_insert);
if($result){
    echo "insert successfull";
}
else {
    echo "insert failed" . mysql_error($result);
}

?>

I unfamiliar with Arduino programing but might be able to help with basic troubleshooting.

You posted two different errors 400 and 403. Which one is correct?

On the server itself you should be able to check your php script by entering:

http://localhost/connect.php?sensor=1 (or whatever is a suitable value for your sensor).

Using the example as a guide I would first try sending a fixed value. The two examples show different methods but try the first.

 if (client.connect(server, 80)) {
    client.println("GET /connect.php?sensor=1 HTTP/1.1");
    client.println();
