Upload a File Into Your hosted Folder

It's too easy to upload a file into your hosted Folder.
At first we need to create a HTML page a Upload.php page  and Create a Folder in the hosting place.

----------------------------------------------------------------------
index.html:
----------------------------------------------------------------------
<head>

      <title>

               Uploading A file

      </title>

</head>
<body>
<table align="center" border="1">
<form enctype="multipart/form-data" action="Upload.php" method="POST">
<tr>
<td>Choose a file to upload:</td>
<td><input type="hidden" name="MAX_FILE_SIZE" value="100000" /> <input name="uploadedfile" type="file"/></td>
</tr>
<tr>
  <td>If the File is Chosen than<br /> Click Upload Button </td>
  <td align="center"><input type="submit" value="Upload File" /></td>
</tr>
</form>
</table>

</body>

Connect with the PHP MySQL Database

You must create a connection to the database, Than  you can access data in a database. In PHP, it is done with the function name  mysql_connect() .

// mysql_connect("servername","username","password");

Q.What is "servername"?

Ans= It is Optional. Specifies the server to connect to.And the Default value is "localhost".

Q.What is "username"?

Ans= It is Optional.Specifies the username to LOGIN with. The Default value is the name of the User that owns the server process.

Q.What is "password"?

Ans=  It is Optional. Specifies the password to LOGIN with. Default value is "  ". That means NULL.

------------------------------------------------------------------------------

Total code 
------------------------------------------------------------------------------

<?php

session_start();

$connect = mysql_connect("localhost","mint_php","MeHeDi");

//server="localhost" userName= "mint_php " pass=" MeHeDi "

if (!$connect)

  {

  die('Could not connect: ' . mysql_error());

  }
// Here you can write your code

?>

Using Concatenation Operator

Now we are talking about Concatenation.
Concatenation operator (.) [dot] is use to put two string value together.
To concatenate two string value together, use the concatenation operator.      

++++++++++++++++++
<?php
$string1="Hello";
$string2="Welcome to Mint PHP !";
echo $string1. " " .$string2;
?>
++++++++++++++++++

Output:
___________

Hello Welcome to Mint PHP !

______________

There is another method, without using the   .= operator  by this we can join different variable into another variable.
Example:
++++++++++++++++

   <?php
$string1="Hello,";
$string2="World!";
$string3=$string1 . $string2; 
$string4=$string1 . ' and welcome to Mint PHP Blog ' .$string2;

echo $string3.' ' .$string4;

?>

++++++++++++++
Output:
_______

Hello,World! Hello, and welcome to Mint PHP Blog World!
_____________

Outputting A String

Thank you for reading my Blog.
We have done in previous lesson use PHP " echo " .we can also use the "ptint" function as like as C programming.
You can place either a string variable or you can use quotes,like i do below, to create a string that the echo/print function will output.

**************************************
<body>
<?php
$myString="Hello ! Welcome to Mint PHP ";
echo $myString."<br/>";
echo 'I love PHP :)'."<br/>";
print "You can also use print as like as \"echo\".";
?>

A variable is a means of storing a value,such as text string "Hello World" or the integer value.
In PHP you define a variable with the following form :

PHP Variable declaration:
