Structured php programming
Friday, April 18th, 2008
It is very important to separate the functionality in separate files. Each file will be responsible to serve the specific meaningful code.
Lets look at the following code of index.php used at http://webwayworld.com/dynamicworld/index.php
1) index.php
<?php
include “common.php”;
?>
<html xmlns=”http://www.w3.org/1999/xhtml“>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=iso-8859-1″ />
<link href=”<?=HTTP_STYLE.” mainstyle.css”; ?>” rel=”stylesheet” type=”text/css”/>
<title>webwayworld.com</title>
</head>
<body>
<table width=”100%” border=”0″ cellspacing=”0″ cellpadding=”0″>
<tr>
<td colspan=”2″>
<? include ROOT_INCLUDE.”header.php”;?>
</td>
</tr>
<tr>
<td colspan=”2″ align=”right” valign=”middle” class=”website”>
<?
echo ” Experience the web way world with webwayworld.com”;
?>
</td>
</tr>
<tr><td colspan=”2″ align=”center”><? echo ” Discover the php solutions “; ?></td></tr>
<tr>
<td width=”25%” align=”left” valign=”top”>
<table width=”100%” border=”0″ cellspacing=”0″ cellpadding=”5″>
<?php echo “PHP MySQL based <br> web development” ?>
</table>
</td>
<td width=”100%” align=”left” valign=”top”>
<table width=”100%” border=”0″ align=”center” cellspacing=”0″ cellpadding=”5″>
<?php
echo “<h1> Explore web way world….<h1>”; ?>
</table>
</td>
</tr>
</table>
</body>
</html>
2) common.php
<?php
session_start();
$httphost = $_SERVER[’HTTP_HOST’];
$docroot = $_SERVER[’DOCUMENT_ROOT’];
$instal_folder = “/dynamicworld/”;
$rootpath = $docroot.$instal_folder;
$hostpath = “http://”.$httphost.$instal_folder;
include $rootpath.”config.php”;
include ROOT_COMMONDIR.”dbconnect.php”;
include ROOT_FUNCTIONS.”common_functions.php”;
?>
3) config.php
<?php
global $rootpath;
global $hostpath;
global $path_separator;
$path_separator = ‘/’;
define(’ROOT_DIR’, $rootpath);
define(’ROOT_INCLUDE’, $rootpath.”includes”.$path_separator);
define(’ROOT_COMMONDIR’, $rootpath.”commondir”.$path_separator);
define(’ROOT_FUNCTIONS’, $rootpath.”functions”.$path_separator);
define(’ROOT_UPLOADS’, $rootpath.”uploads”.$path_separator);
define(’ROOT_STYLE’, $rootpath.”style”.$path_separator);
/*community and eventcalendar module related root path*/
define(’ROOT_COMMUNITY’, $rootpath.”community”.$path_separator);
define(’ROOT_EVENTCALENDER’, $rootpath.”community/EventCalender”.$path_separator);
define(’ROOT_COMMUNITY_INCLUDE’, ROOT_COMMUNITY.”includes”.$path_separator);
define(’HTTP_DIR’, $hostpath);
define(’HTTP_UPLOADS’, $hostpath.”uploads”.$path_separator);
define(’HTTP_STYLE’, $hostpath.”style”.$path_separator);
/*community and eventcalendar module related http url*/
define(’HTTP_COMMUNITY’, $hostpath.”community”.$path_separator);
define(’HTTP_EVENTCALENDER’, $hostpath.”community/EventCalender”.$path_separator);
?>
4)header.php
<table width=”100%” border=”0″ cellspacing=”0″ cellpadding=”0″>
<tr>
<td height=”10″ class=”website”></td>
