PHP Parse Error...

Ok, IM trying to write the code to my PHP Program that takes a variable from the browser (book.php?page=1)... I think Im going in the right direction but when I try to execute the following code it gives me a parse eroor:

Code:

---

Parse error: parse error, unexpected '\"', expecting T_STRING or T_VARIABLE or T_NUM_STRING in D:\Apache\htdocs\book.php on line 2

---

Here is my PHP code...

PHP Code:

---

<?php
header("location: $_GET["page"]");
if (page = 1) {
    print("www.antionline.com");
}
?>

---

Any suggestionPS: What im trying to get with this code is that it will take the variable(?page=1) read it into the program and redirect the user to a specific output depending on that variable...

Here is somebody with your problem and some solutions.

Quote:

<?php
print "Your first name is $HTTP_POST_VARS['FirstName'].
\n";
print "Your last name is $HTTP_POST_VARS['LastName'].
\n";
print "Your E-mail address is $HTTP_POST_VARS['Email'].
\n";
print "This is what you had to say:
\n $HTTP_POST_VARS['Comments']
\n";
?>

just change the double quotes to single quotes for all $HTTP_POST_VARS[''] variables.

Hope dis helps. :)

Sorry I didn't post the link last time, here it is, http://www.webmasterworld.com/forum13/1223.htm

Ok, Thanks for that help but now thee is another problem..... Ive assigned a variable to page ($page) but whenever I try to access the page to test it it says

Code:

---

Forbidden
You don't have permission to access /$_GET["page"] on this server.


--------------------------------------------------------------------------------

Apache/1.3.26 Server at localhost Port 1337

My code is as follows:

PHP Code:

---

<?php
$page = header('location: $_GET["page"]');
if ($page = 1)
    print "www.antionline.com";
?>

---

Is there an easier way to see what variabe is out into the script then act on it?

You're trying to mix two functions together, acid.

The header('location: page') funcition redirects the browser to another page.
in the array $_GET are the variables you included in the url.

So, the correct version of that script would be:

PHP Code:

---

<?php
$page = $_GET["page"];   // this reads the variable "page" in the array $_GET
if ($page == 1) {
   // do the page one stuff here
}
?>

---

Instead of the if-statement, you might want to use the switch/case statement

PHP Code:

---

<?php
$page = $_GET["page"];   // this reads the variable "page" in the array $_GET
switch ($page) {
   case 1:
      // do the page one stuff here
      break;
   case 2:
      // page two stuff
      break;
   case 3:
      // page three stuff
      break;
    case default:
      // do stuff you need to do when an unexpected value is found
}
?>

---

Oh, and by the way: $HTTP_POST_VARS and $HTTP_GET_VARS are deprecated. Use $_POST and $_GET instead.

You can find a bunch of information on the php.net website. Here's a link to their manual: http://www.php.net/manual/

Guus, How can I get the content to be redirected.... say the content I want for page 1 is perl.pdf... How can I redirect to that

Try this:

PHP Code:

---

<?php
$page = $_GET["page"];   // this reads the variable "page" in the array $_GET
switch ($page) {
   case 1:
      header( "Content-Type: text/plain" );
      readfile( "firstfile.txt" );
      break;
   case 2:
      header( "Content-Type: text/html" );
      readfile( "secondfile.html" );
      break;
   case 3:
      header( "Content-Type: audio/x-wav" );
      readfile( "third.wav" );
      break;
   case 4:
      header( "Content-Type: application/pdf" );
      readfile( "perl.pdf" );
      break;
    case default:
      header( "Content-Type: text/html" );
      readfile( "home.html" );
}
?>

I never actually used this myself, but I'm pretty sure it'll work (save some syntax errors).

Hmmz, I was reading up a bit on php security, sql injection, and other stuff I could find, and I came across this tutorial by chsH. If I understand him correctly, you could filter out all unwanted characters by using the preg_replace() call.

To make sure the variables you GET from your url only include numbers, you could change the line that now reads:

PHP Code:

---

$page = $_GET["page"]; 


---

in:

PHP Code:

---

$page = preg_replace("/[^0-9]/","",$_GET["page"]); 


---

You could also add some length-checking, makeing sure your variables don't include more than a couple of numbers. Read chsh's thread for more information.
