Send Whatsapp Message via PHP Code

 

How to Send and Receive Messages in WhatsApp using PHP


In this tutorial you will see How to Send and Receive Messages in WhatsApp using PHP.

Prerequisite :-

# Chat-API Token , Refer : https://www.phphive.info/255/get-whatsapp-password/



Code:

<?php
 
$chatApiToken = ""; // Get it from https://www.phphive.info/255/get-whatsapp-password/
 
$number = "919999999999"; // Number
$message = "Hello :)"; // Message
 
$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => 'http://chat-api.phphive.info/message/send/text',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS =>json_encode(array("jid"=> $number."@s.whatsapp.net", "message" => $message)),
  CURLOPT_HTTPHEADER => array(
    'Authorization: Bearer '.$chatApiToken,
    'Content-Type: application/json'
  ),
));
 
$response = curl_exec($curl);
curl_close($curl);
echo $response;



Sample Output :

For Receiving Messages

Refer : http://chat-api.phphive.info/docs#/device/messagesRequest

Q : Is There any Daily Limit for Using this API ?

Ans : No! There’s No Daily Limit. But Spamming is Obviously not allowed. We are keeping records of IP’s, if we find someone Spamming our Service then that IP will be Banned.

Drawing driving route directions between two locations using Google Directions in Google Map Android API V2

by
Karthikeyan R

In this article, we will develop an Android application which facilitates users to tap two locations in the Google Map. On taping the second point, a driving route will be drawn in the Google Map Android API V2 using Google Directions API.

This application is developed in Eclipse (4.2.1) with ADT plugin (21.1.0) and Android SDK (21.1.0) and tested in a real device (Android 2.3.6  -  GingerBread ).


Get the API key for Google Maps Android API V2

We need to get an API key from Google to use Google Maps in Android application.
Please follow the given below link to get the API key for Google Maps Android API v2.



Add Android Support library to this project

By default, Android support library (android-support-v4.jar ) is added to this project by Eclipse IDE to the directory libs. If it is not added, we can do it manually by doing the following steps :
  • Open Project Explorer by Clicking “Window -> Show View -> Project Explorer”
  • Right click this project
  • Then from popup menu, Click “Android Tools -> Add Support Library “

Update the layout file res/layout/activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >
    <fragment
        android:id="@+id/map"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>

Create a new class namely “DirectionsJSONParser” in the file src/in/wptrafficanalyzer/locationroutedirectionmapv2/DirectionsJSONParser.java

package in.wptrafficanalyzer.locationroutedirectionmapv2;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import com.google.android.gms.maps.model.LatLng;
public class DirectionsJSONParser {
    /** Receives a JSONObject and returns a list of lists containing latitude and longitude */
    public List<List<HashMap<String,String>>> parse(JSONObject jObject){
        List<List<HashMap<String, String>>> routes = new ArrayList<List<HashMap<String,String>>>() ;
        JSONArray jRoutes = null;
        JSONArray jLegs = null;
        JSONArray jSteps = null;
        try {
            jRoutes = jObject.getJSONArray("routes");
            /** Traversing all routes */
            for(int i=0;i<jRoutes.length();i++){
                jLegs = ( (JSONObject)jRoutes.get(i)).getJSONArray("legs");
                List path = new ArrayList<HashMap<String, String>>();
                /** Traversing all legs */
                for(int j=0;j<jLegs.length();j++){
                    jSteps = ( (JSONObject)jLegs.get(j)).getJSONArray("steps");
                    /** Traversing all steps */
                    for(int k=0;k<jSteps.length();k++){
                        String polyline = "";
                        polyline = (String)((JSONObject)((JSONObject)jSteps.get(k)).get("polyline")).get("points");
                        List<LatLng> list = decodePoly(polyline);
                        /** Traversing all points */
                        for(int l=0;l<list.size();l++){
                            HashMap<String, String> hm = new HashMap<String, String>();
                            hm.put("lat", Double.toString(((LatLng)list.get(l)).latitude) );
                            hm.put("lng", Double.toString(((LatLng)list.get(l)).longitude) );
                            path.add(hm);
                        }
                    }
                routes.add(path);
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }catch (Exception e){
    }
    return routes;
    }
    /**
    * Method to decode polyline points
    * */
    private List<LatLng> decodePoly(String encoded) {
        List<LatLng> poly = new ArrayList<LatLng>();
        int index = 0, len = encoded.length();
        int lat = 0, lng = 0;
        while (index < len) {
            int b, shift = 0, result = 0;
            do {
                b = encoded.charAt(index++) - 63;
                result |= (b & 0x1f) << shift;
                shift += 5;
            } while (b >= 0x20);
            int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
            lat += dlat;
            shift = 0;
            result = 0;
            do {
                b = encoded.charAt(index++) - 63;
                result |= (b & 0x1f) << shift;
                shift += 5;
            } while (b >= 0x20);
            int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
            lng += dlng;
            LatLng p = new LatLng((((double) lat / 1E5)),
                (((double) lng / 1E5)));
            poly.add(p);
        }
        return poly;
    }

}
