CELLSPACING controls the space between table cells.

CELLPADDING sets the amount of space between the contents of the cell and the cell wall.


WHY PHP??

  • Php is Hypertext Preprocessor.
  • Php is an interpreted language, i.e., there is no need for compilation.
  • Php is a server-side Scripting Language.
  • Php is an Object-Oriented Language.


Easy to Use:
        Code is embedded to HTML.
         Easy to Learn.
         Case sensitive

Cross-Platform:
        Runs on almost any server on several operating systems.
        Wide range of supported database.
          








Install XAMPP: https://www.apachefriends.org/download.html

Now fire on GUYZZ for our next big step towards PHP 💣💣

Full form of XAMPP is : 
X (cross-platform), Apache, MySQL, PHP, Perl
For Internal Server and Database in our system, we have to use it.

Now after installing XAMPP start MySql and Apache .



Now create a Folder in -- installation_directory:\xampp\htdocs\php_svt_2

here In this Folder, we will do the next operations.

Using PHP in HTML:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-=8">
<title>First PHP Program</title>
</head>
<body>
<?php
echo "Hello World";   //for Printing line in PHP
?>
</body>
</html>




Save this in our folder php_svt_2  & give it .php extension.

Now open your browser and type: http://localhost/php_svt_2/



You can see this type now open your PHP file and you can see the printed line:




We can start Php code-writing from below::

<?php   ?>  --   Standard type Embedding
<?          ?> --   Short type Embedding
<%       %> --  .net type Embedding

**Short Type does not support Asynchronous Data.
**Standard type embedding supports Asynchronous & synchronous data

Synchronous data: Submitting the Data from Client to the server with Submit Button.
Asynchronous data: Submitting the Data from Client to the server without Submit Button.


<?          ?> 
<%       %> 

 **This two is not active in Real-time server we have to activate it manually, The best option is we use the default type embedding  --   ðŸ˜†

<?php   ?>


To activate other types Embedding : :




Click Config >> PHP(php.ini) >> 


Then from here activate that other types of Embedding.

DEFINING VARIABLE IN PHP :

  $a =25;   ✌
  $b=25.9; ✌




O/P: 


Addition in PHP:




PHP $ and $$ Variables :

$Var is a normal variable with the name var that stores any value like string, integer, float etc.
$$Var is a reference variable that stores the value of the $variable inside it.

Ex-1:
<?php
$x="abc";
$$x=200;
echo $x."<br/>";
echo $$x."<br/>";
echo $abc;
?>

O/P:

abc
200
200


Different Types of Loops :

  1. While loop
  2. Do-While loop
  3. for loop
  4. for each loop

Code:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-=8">
<title>Loop</title>
</head>
<body>
<?php
$n=1;
while($n<=10){
echo $n;
$n++;
}

?>
</body>
</html>

O/P: 1 2 3 4 5 6 7 8 9 10


<!DOCTYPE html>
<html>
<head>
<meta charset="utf-=8">
<title>Loop</title>
</head>
<body>
<?php
$n=1;
while($n<=10){
if($n%2==0)
{
echo $n;
}
$n++;
if($n==7){
break;
}
}
?>
</body>
</html>




<!DOCTYPE html>
<html>
<head>
<meta charset="utf-=8">
<title>Loop</title>
</head>
<body>
<?php
do{
echo $n;
$n++;

}while($n<=7);

?>
</body>
</html>

O/P: 1 2 3 4 5 6 7

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-=8">
<title>Loops</title>
</head>
<body>
<?php
for($i=1;$i<11;$i++)
{
echo $i."<br>"
}
?>
</body>
</html>
