header and footer
|
It willl display in every page
|
|
in every html pages, some elements are common, so instead of
creating in every page, we can create in one page , we can use that one in
all pages
|
|
|
instead of writing in every page , can we write in all pages
from one page
|
|
|
save file as headerinc.php
|
|
|
<?php
|
|
|
echo '<h1> telugu computer wold learn</h1>' ;
|
like a template
|
|
?>
|
|
|
|
|
|
page1
|
|
|
<?php
|
|
|
include 'headerinc.php';
|
in which page u require write like this , It will print that
header inc file data
|
|
?>
|
|
|
<?php
|
|
|
require 'headerinc.php';
|
if headerinc file is not available ,It ells error and it will
not execute after that code
|
|
echo 'this is a test para';
|
destroyed if file is not there
|
|
?>
|
|
|
<?php
|
|
|
include 'headerinc.php';
|
if headerinc file is not available ,It ells error and it will
execute after that code
|
|
echo 'this is a test para';
|
|
|
?>
|
|
|
include once and require once
|
|
|
include '../headerinc.php';
|
if we write include once, then write include, it will execute,
that’s the procedure
|
|
if we include only one time , it is useful
|
|
|
include_once '/headerinc.php';
|
|
|
require_once 'headerinc.php';
|
|
|
include_once 'headerinc.php';
|
it will display the values presnt in that file
|
|
include 'headerinc.php';
|
it will display the values presnt in that file
|
|
if we need same file we will use include_once
|
|
|
include 'headerinc.php';
|
only this file is execute
|
|
include_once 'headerinc.php';
|
it will not display
|
|
include 'headerinc.php';
|
it will display the values presnt in that file
|
|
include 'headerinc.php';
|
it will display the values presnt in that file
|
| headerinc.php |
| echo |
