Calling environment variable from

[npereira]

Here is my code:

Code: Select all

<?

include "inc/loader.php";


        $query = "SELECT * FROM ".DB_PREFIX."_intro";
   $content = mysql_fetch_object(mysql_query($query));
        $filename = "/home/e-smith/files/primary/html/$content->effect.txt";
        $success = @unlink($filename);
        $filename = "/home/e-smith/files/primary/html/$content->effect.swf";
        $success = @unlink($filename);


I would like to have the '$filename' path to be insertered automaticaly since the path will be different on each server.

How can I acheive this?

I want the document root to be taken from the environment and then append '/$content->effect.txt'

Regards,

Found a fix. Thought I would post here in case someone else asks.

What I did is just replace

Code: Select all

$filename = "/home/e-smith/files/primary/html/$content->effect.txt";


With

Code: Select all

$filename = $DOCUMENT_ROOT/$content->effect.txt";


Thanks anyway,

Nice fix
I saw your post, but I didn't know how to fix it..
This function is new for me, but now not anymore.
Where did you find it?? I can't find any reference..
I guess it gives the relative path from the root directory.

ThanX for sharing!

I looked around the net and on the PHP manual (got the welp file on my desktop) and looked around in environement variables. There is alot you can do with variables and system variables other than Document root.

Here is a link to a document you should read if your interested in environment variables;
http://www.phpbuilder.com/manual/language.variables.predefined.php

phpbuilder.com/manual has very good stuff in it.

Also, place the following in a file named variables.inc in the current directory.

Code: Select all

<?php

// Print Environment Variables
 echo "<b>Environment Variables from \$HTTP_ENV_VARS</b><br><br>";
  reset($HTTP_ENV_VARS);
   while (list ($key, $val) = each ($HTTP_ENV_VARS)) {
  print $key . " = " . $val . "<br>";
 }

// Print GET Variables
 echo "<br>";
 
 echo "<b>GET Variables from \$HTTP_GET_VARS</b><br><br>";
  reset($HTTP_GET_VARS);
   while (list ($key, $val) = each ($HTTP_GET_VARS)) {
  print $key . " = " . $val . "<br>";
 }

// Print POST Variables
 echo "<br>";
 
 echo "<b>POST Variables from \$HTTP_POST_VARS</b><br><br>";
  reset($HTTP_POST_VARS);
   while (list ($key, $val) = each ($HTTP_POST_VARS)) {
  print $key . " = " . $val . "<br>";
 }

// Print COOKIE Variables
 echo "<br>";
 
 echo "<b>COOKIE Variables from \$HTTP_COOKIE_VARS</b><br><br>";
  reset($HTTP_COOKIE_VARS);
   while (list ($key, $val) = each ($HTTP_COOKIE_VARS)) {
  print $key . " = " . $val . "<br>";
 }

// Print SESSION Variables
 echo "<br>";
 
 echo "<b>SESSION Variables from \$HTTP_SESSION_VARS</b><br><br>";
  reset($HTTP_SESSION_VARS);
   while (list ($key, $val) = each ($HTTP_SESSION_VARS)) {
  print $key . " = " . $val . "<br>";
 }
 
?>


Call the file with the following at any point in your page where you would like the variables output.

Code: Select all

<?php
  require("variables.inc");
?>

Later!
