Error submitting form

Hello, I am sending a form which gives me the following error:SyntaxError: Unexpected number.
This is the function that sends to the server:

enviarFormProfesional(){
let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded'});
let options = new RequestOptions({ headers: headers });
this.datos="tipo=nuevoProfesional&nombre="+this.nombre+"&apellido="+this.apellido+"&correo="+this.correo+"&pais="+this.pais+"&telefono="+this.telefono+"&clave="+this.clave+"&ciudad="+this.ciudad+"&postal="+this.postal+"&seguroSocial="+this.segurosocial+"&recibirCopiaAntecedentes="+this.copiaseguridad+"&sesion="+this.sesion+"&servicio="+this.servicio+"&fotoLiencia="+this.fotolicencia+"&fotoFace="+this.fotoprofesional;
this.http.post('http://developerwym.com.ve/enki/recibe.php',this.datos,options).map(res => res.json()).subscribe(data => {alert(data.data);},err =>{alert("Error! Form Profesional:"+err);});

}

Depending on the result of the insertion I return a json like this:
$ StatusRegister [] = array (“status” => 0) // if it is ok
$ StatusRegister [] = array (“status” => 1) // if it gives error
