php page to redirect to another - php

Question

I have a php page which should be included in otherpage but no directly. Lets assume it as 1.php and the other page as 2.php
1.php
<?php
if($_SERVER['REQUEST_URI'] == "/1.php"){
header("Location:2.php");
}
else
{
//some code here
}
?>
2.php
<?php
include("1.php");
?>
this worked well on localhost/1.php and have been redirected to localhost/2.php
but this had made a problem with localhost/1.php?somegetmethod=data I found that anyone can access this page by typing ?something=something at the end of 1.php url. How to change the code which can redirect all url which starts with localhost/1.php

Answer 1

you could check if a substring is at a given position like this
if(strpos($_SERVER['REQUEST_URI'], "/1.php") === 0) {
this checks if the REQUEST_URI starts with /1.php (= is at position 0)

Answer 2

Use $_SERVER['PHP_SELF'] instead of $_SERVER['REQUEST_URI'].

Answer 3

try it:
if($_SERVER['SCRIPT_NAME'] == "/1.php")

Answer 4

$_SERVER['REQUEST_URI'] contains URI of requeted page, in yoour case it's 1.php?somegetmethod=data.
Change code like:
if(strpos($_SERVER['REQUEST_URI'], "/1.php") === 0){
header("Location:2.php");
}else{
//some code here
}

Answer 5

What you often see, for instance in MediaWiki, WordPress and many other such applications, is this:
1.php
if ( !defined( 'YOURAPPCONSTANT' ) ) {
// You could choose to redirect here, but an exit would make just as much
// sense. Someone has deliberately chosen an incorrect url.
echo "Cannot directly call this file.";
exit( 1 );
}
2.php
define('YOURAPPCONSTANT', 'It is defined');
include('1.php');
That way, 2.php is the entry of your application, regardless of the url used to reach it. I think this is a much safer and more flexible way, and it is used so often for a reason.
