file config.inc.php :

<?php   $username = "*****";  $password = "****";  $host = "*****";  $dbname = "*****";   $options = array(pdo::mysql_attr_init_command => 'set names utf8');   try  {      $db = new pdo("mysql:host={$host};dbname={$dbname};charset=utf8", $username, $password, $options); mysql_set_charset('utf8'); }  catch(pdoexception $ex)  {      die("failed connect database: " . $ex->getmessage());  }    $db->setattribute(pdo::attr_errmode, pdo::errmode_exception);      $db->setattribute(pdo::attr_default_fetch_mode, pdo::fetch_assoc);   if(function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc())  {      function undo_magic_quotes_gpc(&$array)      {          foreach($array &$value)          {              if(is_array($value))              {                  undo_magic_quotes_gpc($value);              }              else              {                  $value = stripslashes($value);              }          }      }       undo_magic_quotes_gpc($_post);      undo_magic_quotes_gpc($_get);      undo_magic_quotes_gpc($_cookie);  }  ?> 

addition file :

<?php  require("config.inc.php");  $query = "insert news (  news_date, news_title, news_body ) values ( :news_date, :news_title, :news_body ) "; $query_params = array(     ':news_date'  => $_post['news_date'],     ':news_title' => $_post['news_title'],     ':news_body'  => $_post['news_body'] );    try  {     $stmt   = $db->prepare($query);     $result = $stmt->execute($query_params);  } catch (pdoexception $ex)  {     $response["success"] = 0;     $response["message"] = "database error. couldn't add news!";     die(json_encode($response)); }  $response["success"] = 1; $response["message"] = "news added!"; echo json_encode($response); ?> 

in android project : java file :

public class addnews extends dialog {  private activity mactivity;  private edittext mnewstitleet; private edittext mnewset;  private button mpublishbtn; public string username;  jsonparser jsonparser = new jsonparser();  private string add_url =         "http://yazanyazan3.esy.es/newssite/addnews.php";  public addnews(activity mactivity) {     super(mactivity);     this.mactivity = mactivity; }  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     requestwindowfeature(window.feature_no_title);     setcontentview(r.layout.activity_addnews);      mnewstitleet = (edittext) findviewbyid(r.id.title_news);     mnewset      = (edittext) findviewbyid(r.id.news_box);     mpublishbtn  = (button) findviewbyid(r.id.publish_btn);      bundle use =getintent().getextras();     username = use.getstring("name");      mpublishbtn.setonclicklistener(new view.onclicklistener()     {         @override         public void onclick(view view)         {             attempadding();         }     }); }  private void attempadding() {     if (!mnewstitleet.gettext().tostring().equals("") &&             !mnewset.gettext().tostring().equals(""))     {         new addnewstask().execute();     }     else     {         toast.maketext(mactivity.getapplicationcontext(),                 "all fields requires", toast.length_long).show();     } }   public intent getintent() {     return mactivity.getintent(); }   private class addnewstask extends asynctask<void, void, boolean> {     private progressdialog mprogressdialog;      private jsonobject jsonobjectresult = null;      private string error;      @override     protected void onpreexecute()     {         super.onpreexecute();         mprogressdialog = progressdialog.show(addnews.this.getcontext(),                 "processing...", "adding new news", false, false);     }      @override     protected boolean doinbackground(void... params)     {         dateformat dateformat = new simpledateformat("yyyy-mm-dd");         date date = new date();           list<namevaluepair> pairs = new arraylist<namevaluepair>();         pairs.add(new basicnamevaluepair("news_user",username));         pairs.add(new basicnamevaluepair("news_date", dateformat.format(date).tostring()));         pairs.add(new basicnamevaluepair("news_title", mnewstitleet.gettext().tostring()));         pairs.add(new basicnamevaluepair("news_body", mnewset.gettext().tostring()));           jsonobjectresult = jsonparser.makehttprequest(add_url+"?user="+username+"", pairs);          if (jsonobjectresult == null)         {             error = "error in connection";             return false;         }          try         {             if (jsonobjectresult.getint("success") == 1)             {                 error = jsonobjectresult.getstring("message");                 return true;             }             else                 error = jsonobjectresult.getstring("message");          }         catch (exception ex)         {          }          return false;     }      @override     protected void onpostexecute(boolean aboolean)     {         super.onpostexecute(aboolean);         mprogressdialog.dismiss();         toast.maketext(mactivity.getapplicationcontext(), error, toast.length_long).show();         dismiss();     } } } 

in database, choose utf8 . , tried solutions did not work . please help.

hope these tips :

try adding static text database in addition file (do not read request) can divide problem 2 parts , can see if problem android client php server or php server database :

<?php  /*   please type arabic string(salam) own keyboard , not    copy version because used persian keyboard. */ $arabic_string = 'سلام';  file_put_contents("arabic_file", $arabic_string);  $query_params = array(     ':news_date'  => $_post['news_date'],     ':news_title' => $_post['news_title'],     ':news_body'  => $arabic_string );  ?> 

now check both "arabic_file" content , database.

-if file not ok(contained gibberish) problem php server(like maybe not support arabic language,...).

-if database not ok(gibberish again) maybe problem database or way php's pdo inserting data database, , should specify encoding connection :

$connection_str = "mysql:host=$host;dbname=$db;charset=utf8"; 

-if ok problem way arabic strings coming android device.
