Q1.A variable:
Variable is nothing it is just name of the memory location. A Variable is simply a container i.e used to store both numeric and non-numeric information.
Rules for Variable declaration
- Variables in PHP starts with a dollar($) sign, followed by the name of the variable.
- The variable name must begin with a letter or the underscore character.
- A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
- A variable name should not contain space
Assigning Values to Variables
Assigning a value to a variable in PHP is quite east: use the equality(=) symbol, which also to the PHP's assignment operators.
This assign value on the right side of the equation to the variable on the left.
ex:
<?php
$myCar = "Honda";
echo $myCar;
?>
Answer Q1 B
$_SERVER :- $_SERVER is an array which holds information of headers, paths, script locations. Web server creates the entries in the array. This is not assured that every web server will provide similar information, rather some servers may include or exclude some information which are not listed here.
$_SERVER has following basic properties:
1. Set by web server.
2. Directly related to the runtime environment of the current php script.
3. It does the same job as $HTTP_SERVER_VARS used to do in previous versions of PHP

Answer Q1 D
The include() Function
The include() function takes all the text in a specified file and copies it into the file that uses the include function. If there is any problem in loading a file then the include() function generates a warning but the script will continue execution.
Assume you want to create a common menu for your website. Then create a file menu.php with the following content.
<a href="http://www.secretmind.cf/index.htm">Home</a> -
<a href="http://www.secretmind.cf/ebxml">ebXML</a> -
<a href="http://www.secretmind.cf/ajax">AJAX</a> -
<a href="http://www.secretmind.cf/perl">PERL</a> <br />
Now create as many pages as you like and include this file to create header. For example now your test.php file can have following content.
<html>
<body>
<?php include("menu.php"); ?>
<p>This is an example to show how to include PHP file!</p>
</body>
</html>
