Im making a site for my sisters school club, but in all this i wanna use it for my index.php and not have a question. So how would i do that? if($_GET['']) is that it? because for the last thing im going to add else to it for a 404 error.

Can you restate your question?

cam u use the if get for the index? like not index.php? but just for the index?

Well, I still can't understand what exactly your question is. So, the only advice I can give you is:

Try whatever it is you are wondering about. If it doesn't work, try something else. If that doesn't work. Try something else. If the third thing doesn't work, then post your code here with any error messages, and carefully explain what you are trying to do. Help us help you.

I think he's trying to say this:

S/He is developing a page for his sisters school club and he wants to use this page as his/her own index page for his own website. So s/he'd like to know if s/he can use if($_GET['page']) to switch between the two sites or not.

Is that it? Something along those lines? If so, yes, you can use index.php to switch between which site is seen by visitors using the if($_GET['page']) statement. It would most likely go something like:

URL:http://www.domain.com/index.php?p=1

<?php
if($_GET['p']==1)
{
  // The user wants to go to page 1 on the other site, send them there
  header("Location: http://www.domain2.com/index.php");
}
elseif($_GET['p']==2)
{
  // Now they want to go to your sites main page
  header("Location: http://www.domain.com/main.php");
}
else
{
  // Otherwise, we'll direct them to your sites main page
  header("Location: http://www.domain.com/main.php");
}
?>

Something like that?

no. To display the content for the site im usign php, one file containg loads of text ib php. Im using the if (get) and then the swich function and case to diplay text. So like if($_(get['image'])) w/e the rite code if for that. Swich(get['image']) or w/e the code is, case kelly: echo "Hi, kelly"; case bob: echo "hi, bob"; break;. or /e the rite code is. Well is their anyway to use the ifget for the index page or just the site url? like i mean can u use that fuinction for just www.mysite.com or www.mysite.com/index.php. ? or no?

Well, if someone visits your page and uses the URL: mysite.com/?image=kelly, then the $_GET[] array will have a variable "image" with a value "kelly". So, yes it can work. It will work both ways since the default page will be index.**** (whatever the extension is, depends on Apache config, and what files are in the folder). If you only have an index.php file, then the two urls are synonymous (meaning they mean the same thing).

no, idk about that im wondering how can i use that feture for the index. not the ?something just the index.php

bpat1434

you can't. GET variables are passed via the URL with ?variable=value&variable=value paris. So without the ?variable=value, you would have an empty $_GET[] array.

ok so what should i use? for if it finds that ur on the main page to diplay text?

bpat1434

Explain what you want again. You never clearly said what you want to do. Take some time to think it out. Take as long as you need to explain it, I'll read it. We're having trouble getting you an answer to what you want, since we aren't sure what the question is.

Pretty much can i use the if($get['']) statement to do this?

if($_get[''])//this for index like www.mysite.com, or www.mysite.com/index.php?
{
echo "<h1>Welcome</h1>";
}

if not is their some other way?

bpat1434

You are still being ambiguous. if($get['']) what? $GET references variable=>value pairs put through the URL in the form of ?variable=value. Are you trying to check to see if they are looking at ".com/index.php" versus ".com/"?

If statements evaluate the expression contained within the parenthesis. If it evaulates to true, then it executes the code between the curly braces. What your code is doing is nothing, and extremely confusing.
