PHP Index

Basic index.php

<?php
### This definition is so that any included scripts can check against it and if this isn't defined they won't run.
define("myprogram",1);

### Variables you can change
$site_title = "Site Title";

### Start the Session
session_start();
$sessid = session_id();

### php.ini configurations
# If you use .htaccess, add the following to increase upload size (There's other values in the ini_set() syntax below)
# php_value upload_max_filesize 15M
# php_value post_max_size 15M
#
# If you want to use the built in ini_set() function, uncomment the following to allow larger uploads and other options.
# ini_set("upload_max_filesize","15M"); ### Change upload size
# ini_set("post_max_size","15M"); ### Change upload size
# ini_set("max_execution_time","86400"); ### Set script timeout in seconds
# ini_set("max_input_time","86400"); ### Set max input time in seconds
# ini_set("memory_limit","32M"); ### Change the memory limit

### MySQL Database Configuration
#$my['username'] = "mysql username";
#$my['password'] = "mysql password";
#$my['hostname'] = "mysql hostname";
#$my['port_number'] = "mysql port number";
#$my['database'] = "mysql database";

#$myid = mysql_pconnect($my['hostname'].":".$my['port_number'],$my['username'],$my['password']);
#mysql_select_db($my['database'],$myid);

### Retrieving POST and GET requests
$var_post = isset($_POST['var_post']) ? $_POST['var_post'] : NULL;
$var_get = isset($_GET['var_get']) ? $_GET['var_get'] : NULL;
$action = isset($_GET['action']) ? $_GET['action'] : NULL; # Used in the Action's section below.

### Retrieving command line arguments in Command Line Interface (CLI) mode
### Usage at command line: php myscript.php argument1 argument2
#$arg1 = $_SERVER['argv'][1]; # If using CLI mode, this is the first argument. 0 is the script itself.
#$arg1 = $_SERVER['argv'][2]; # If using CLI mode, this is the second argument.

### Constant variables (Remember and don't overwrite them.)
$httphost = $_SERVER['HTTP_HOST']; # www.example.com
$useragent = $_SERVER['HTTP_USER_AGENT']; # Mozilla ... Firefox
$referer = $_SERVER['HTTP_REFERER']; # page that sent you to this one
$remoteip = $_SERVER['REMOTE_ADDR']; # requesting ip address
$qs = $_SERVER['QUERY_STRING']; # query string
$requesturi = $_SERVER['REQUEST_URI']; # /path/phpinfo.php?querystring=included
$phpself = $_SERVER['PHP_SELF']; # /path/phpinfo.php (query string not included)

### Initialize any variables here.
$html = $page_content = "";

### Actions
# login.php should contain your login process. It can also populate the $page_content variable.
# javascript.php should set the $javascript variable which will be printed in the html <head>
#      tag between <script> tags.
# myprogram.php should contain $action's and should return the $page_content variable which
#      gets printed in the <body> of the html.
# Sample syntax for each of these included files obeying the definition at the top of index.php.
# &lt;?php if(!defined("myprogram")){ exit(0); }
#       /* Your code goes here. */
# ?&gt;
# Sorry, &lt; = < and &gt; = >. Make sure you change those when creating the files below that are required.
###
#require_once("ssi/login.php");
#require_once("ssi/javascript.php");
#require_once("ssi/myprogram.php");

### Put everything that will go between <body> and </body> in the $page_content variable.
$page_content .= "<div><p><a href=\"http://validator.w3.org/check?uri=referer\"><img style=\"border:0;\" src=\"http://www.w3.org/Icons/valid-xhtml10-blue\" alt=\"Valid XHTML 1.0 Strict\" height=\"31\" width=\"88\" /></a></p></div>";

### $html is the variable that should be printed at the very end of the script. This is the actual HTML page.
$html .= <<<eof
