PHP newbie alert

Often, I see websites that link to the other pages by linking to the same PHP file, but adding different queries. Example: This forum. Every thread is requested from the same showthread.php, but with a different query like ?tid=45715.

How do I do this?

Hope that makes sense. If not, please ask me to clarify.

well this forum uses the tid get value to know what thread to grab from the database , but i think you want to use something really simple like

code:

---

<?php
$x = isset($_GET['page']) ? $_GET['page'] : 'home';
if($x=='about'){?>
<--- about page html here --->

<? }else if($x=='other'){ ?>

<--- other page html here --->

<?}else{?>

<--- defult page html here --->
<? }?>

---

Yes, that's what I wanted, not using my database. Thank you. Have a cookie . Hmmm ... that cookie doesn't look that great, have a drumstick as well . I think that I'll use it with  $_REQUEST instaed of $_GET.

[off topic]
Is there a bit of myCode equivalant to <pre>?
[/pff topic]

If the file gets really big, will it slow down the site?

Guido, we need yummy-looking cookies .

Update: Yay, now I forgot         where I wanted to use this .
Update: Yay, now I remember     where I wanted to use this . Where are my Post-its?

If the file gets really big, it might slow the server slightly.

And the closest to a BBcode equivalent of <pre> is [code].[/code]

I would do something like this...

code:

---

<header>
<?php
if (!$a) { $a = "home"; }

include $a.".txt";
?>
<footer>

then have a file for each page, so index.php?a=links would load links.txt in the middle of the page. This way is better i think because you can add new pages without changing the main file.

you should put those files in another folder, then they could only do that if they use ../

code:

---

<header>
<?php
if (!$a) { $a = "home"; }

include somefolder.$a.".txt";
?>
<footer>

I use it on my website too, I have it like this

I hope it's secure else tell me how to make it better

code:

---

function pagina ($page){
   $pad = "paginas/".$page.".php";
   if(!file_exists($pad))
   {
      include("paginas/notfound.php");
   }
   else
   {
      include($pad);
   }
}
if(!isset($_GET["pagina"]) OR $_GET["pagina"] == "")
{
   pagina("home");
}
else
{
   pagina($_GET["pagina"]);
}

---

ive always done it like this:

code:

---

<?php
$page = htmlentities($_GET['page']) ;
if (!isset($_GET['page'])) {
include ("home.php");
}
else {
$filename = "pages/$page.php";
if (file_exists($filename)) {   
include("pages/$page.php"); }
else {   
echo "Sorry, The Page Cannot Be Found";}
}
?>

Just to clear up:

Does the "!" used in some of those make things negative/false?

What does the "." that is used in some of your suggestions do?

So is this PHP:

code:

---

echo 'some text'.$variable

---

code:

---

document.writeln ('some text' + variable)

---

the same as this JavaScript:

code:

---

document.writeln ('some text' + variable)

---

---

code:

---

echo 'some text'.$variable;

yea except you need a semi colon at the end of the php

And except javascript runs on the browser, leaving all the execution in hands of the viewer and PHP runs on the server, hidden to all.

But the effect might be the same, yeah.
