1. FORM VALUE PASSING

2. Include  Include files are files that are interpreted as part of a program at runtime. Include files usually contain program code or HTML code, but they can also contain other information (such as JavaScript code).  The include statement follows this syntax:  include(‘/path/filename’);

3. Including HTML Code  The following example includes the files top.php and bottom.php, which simply contain HTML code, in their respective positions within the program: <?php /* demonstrates use of include() with HTML code in include file */ include(‘top.php’); ?> Hello! <?php include(‘bottom.php’); ?>

4.  For example, perhaps the file top.php looks like this: PHP By Example  and bottom.php looks like this:

5. Including PHP Code  Using include with PHP code is similar to using it with HTML code. However, ensure that your PHP code is enclosed in PHP tags in the include file. <?php /* demonstrates include with PHP code in include file */ include(‘config.php’); ?> Hello, !

6.  Perhaps config.php contains something like this: <?php /* Configuration code */ $user_name = “John Smith”; ?>

8. Reading Variable  Reading variable from Web browser have 2 type:  GET is basically for just getting (retrieving) data. the user agent takes the value of action, appends a ? to it, then appends the form data set, encoded using the application/x- www-form-urlencoded content type. The user agent then traverses the link to this URI. In this scenario, form data are restricted to ASCII codes.  POST may involve anything, like storing or updating data, or ordering a product, or sending E-mail. the user agent conducts an HTTP post transaction using the value of the action attribute and a message created according to the content type specified by the enctype attribute.

9. For example(Textbox) /* form_ex.php */ //for GET //for POST login: password:

10. getPass.php <?php $login=$_GET['login']; $password=$_GET['password']; ?> Use GET Variable Your login = Your password =

11. postPass.php <?php $login=$_POST['login']; $password=$_POST['password']; ?> Use POST Variable Your login = Your password =

12. For example(Textarea) /* form_txt_area */ TEXTAREA /* txt_area.php */ <? $test=$_POST['textarea_test']; echo "textarea_test = ". $test; ?>

13. For example(Radio) /* form_radio.php*/ Select Sex Male Female /* radio_btt.php */ <? $sex=$_POST[sex']; echo " Radio_test = ". $sex; ?>

14. For example(List) /* form_list.php*/ 1-5 6-10 11-15 16-20 Over 21 /* listmenu.php */ <? $age=$_POST['select_old']; echo " List Menu_test = ". $ age; ?>
