PHP MYSQL Login and Registration using Functions

// siddhu vydyabhushana // 122 comments
Today am going to explain you the code for Login and Registration using functions in php,mysql . The best methodology in any language is using Object Oriented Principles.Dealing with classes, objects very easy to manipulate information. Below code for how to develop user registration and login  form in php.

login and registration form using php functions

This tutorial contain only 2 files  functions.php and login_reg.php

Database
simple database with 4 fields id, name, email, password

CREATE TABLE IF NOT EXISTS `javatyro_registration` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` text NOT NULL,
  `email` varchar(100) NOT NULL,
  `password` varchar(100) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=8 ;

Functions.php
class name profile() -> object $profile

<?php
class profile
{
public function db()
{
mysql_connect("localhost","root","")or die(mysql_error());
mysql_select_db("demos") or die(mysql_error());
}
public function registration($name,$email,$password)
{
$query=mysql_query("SELECT * FROM javatyro_registration where email='$email' ");
if(!$query)
{
$query=mysql_query("INSERT INTO javatyro_registration VALUES ('','$name','$email','$password')");
if($query>0)
echo "<h2> hiee..<font color=green>".$name."</font>
</h2><br/><font color=green> You Registered Successfully</font>";
else
echo "<font color=red>failed</font>";
}
else
echo "<h3><font color=red>Sorry,Already Registered</font></h3>";
}
public function login($email,$password)
{
$query=mysql_query("SELECT name FROM javatyro_registration where 
email='$email' AND password='$password' ");
$query=mysql_fetch_array($query);
if($query>0)
echo "<h2> hiee..<font color=blue>".$query['name'].

aspiration-2020 translator

  Translator

In a country of Neverland there are two types of programmers, People who program using a language X(X people) and people who program using a language Y(Y people).
Both are equally good languages but there is no translator that could translate X language to Y and vice versa.Apologists of X and Y can argue for hours proving each other that their programming language is the best one.Y people will tell that their programs are clearer and less prone to errors, while X people will laugh at their inability to instantiate an array of generics or tell them that their programs are slow and have long source code. Another issue that X and Y people could never agree on is identifier naming. In Y a multiword identifier is constructed in the following manner: the first word is written starting from the small letter, and the following ones are written starting from the capital letter, no separators are used.
All other letters are small. Examples of a Y identifier are yIdentifier,longAndMnemonicIdentifier,name,nEERC.Unlike them, X people use only small letters in their identifiers. To separate words they use underscore character "_". Examples of X identifiers are x_identifier, long_and_mnemonic_identifier, name (you see that when there is just one word X and Y people agree), n_e_e_r_c.
Your job is to write a translator that is intended to translate programs in X to Y and vice versa. Of course, identifiers in the translated program must be formatted due to its language rules - otherwise people will never like your translator. 

The first thing you would like to write is an identifier translation routine. Given an identifier,
it would detect whether it is Y identifier or X identifier and translate it to another dialect. If it is neither, then your routine should report an error.
Translation must preserve the order of words and must only change the case of letters and/or add/remove underscores.

Input

N, Number of testcases 0<N<=50
N lines, that contains an identifier. It consists of letters of the English alphabet and underscores. Its length does not exceed 100.

Output

If the input identifier is Y identifier, output its X version. If it is X identifier, output its Y version. If it is none, output "Error!" instead.

Sample Input:

4
long_and_mnemonic_identifier
anotherExample
i
bad_Style

Sample Output:

longAndMnemonicIdentifier
another_example
i
Error!
import java.io.*;

class CharDemo

Alice and Bob are being held at Azkaban(Prison). They want to escape and join Dumbledore's Army.
Alice wants to tell Bob about the details of the plan but wants to keep their escape plan from Dementors(the guards).
So Alice encrypts the message before passing the chits to Bob's cell.
However Bob was careless and he disposed the chits in his cell's waste paper bin.
The clever Dementor found the chits but couldn't make out what they said.
So he hired a computer programmer to decode the message for him. Please help the Dementor to decypher the message.
The code key that Alice used for this simple coding is a one for one character substitution based upon a single arithmetic manipulation of the printable portion of the ASCII character set.

Data Sharing between Android Applications

// siddhu vydyabhushana // 13 comments
In this tutorial I'm going to illustrate how we can share data between two Android applications using Shared Preference.
To implement this I used two Android applications. One is "Datawriter" and the other one is "Datareader".
"Datawriter" is to update shared data. Its' package name is com.writer.data class name is DataWriterActivity . Here is the code for DataWriterActivity class.

package com.writer.data;
import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
public class DataWriterActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        dataWriter();
    }
     
    public void dataWriter(){
        String strShareValue = "Hello! this is shared data";
        SharedPreferences prefs = getSharedPreferences("demopref",Context.MODE_WORLD_READABLE);
        SharedPreferences.Editor editor = prefs.edit();
        editor.putString("demostring", strShareValue);
        editor.commit();
    }
}

dataWriter method will write the string Hello! this is shared data to a shared memory.

Next application is to read shared data. The application name is  Datareader and its' package name is com.datareader class name is DataReaderActivity. Here is the code for DataReaderActivity class.

import android.widget.TextView;
public class DataReaderActivity extends Activity {
 String dataShared;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
         dataRead();
         TextView tv = (TextView)findViewById(R.id.textView1);
         tv.setText(dataShared);
         
    }
     
    public void dataRead(){
      Context con;
         try {
             con = createPackageContext("com.writer.data", 0);
             SharedPreferences pref = con.getSharedPreferences("demopref", Context.MODE_PRIVATE);
             dataShared = pref.getString("demostring", "No Value");
         }
         catch (NameNotFoundException e) {
             Log.e("Not data shared", e.toString());
         }
    }
}

"com.writer.data" in the highlighted line is the package name of the first application which we used to share data.
Following is the out put of second application :

Load Image from URL in Android

// siddhu vydyabhushana // 18 comments
Once I needed to display an image loading from URL in my Android application. After referring some resources I was success. Here I post what I did. This is for future references. I did this for Android 2.2 platform.

This Android application load an image from a server using HttpURLConnection and show it in image view when you click load image button.
(I have used  image located here http://www.codeincloud.tk/play.png)


Here is the layout file.

<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

        android:layout_x="57dp"
        android:layout_y="322dp"
        android:text="Load Image" />

    <ImageView

          catch (MalformedURLException e) {
              e.printStackTrace();
