Errors writing config.php using a setup.php file

[big-dog1965]

Can someone show me why this is adding \ to the data that is writen to a config.php file from my setup.php file. What I have is a setup file that is ran from the browser. I use a form to enter data such as DB connect data and then some other paths and such for parts of other script to use for file locatios. I enter

http://{$_SERVER['HTTP_HOST']}App/Signup/login.php

and when the file is written it adds \ to the line above to the written config.php file like this

	$dbServer="localhost";
$dbUsername="ton1";
$dbPassword="123456789";
$dbDatabase="ton1_App";
$resultpage ="Authenticate.php";
$admin ="admin/index.php";
$success ="members/index.php";
$failure ="failed.php";
$login ="http://{$_SERVER[\'HTTP_HOST\']}App/Signup/login.php";
$logout ="http://{$_SERVER[\'HTTP_HOST\']}App/Signup101/logout.php";
$changepassword ="http://{$_SERVER[\'HTTP_HOST\']}App/Signup/chgpwd.php";
$confirm ="http://{$_SERVER[\'HTTP_HOST\']}App/Signup/confirm.php";
$adminemail ="admin@email.com";

which creates errors like this for all the line that have http://{$_SERVER['HTTP_HOST']} in them

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home/public_html/App/config.php on line 10

Warning: Unexpected character in input: ''' (ASCII=39) state=1 in /home/public_html/App/config.php on line 10

Here the connect stuff in the setup.php file

	// connect to the database
$dbServer=$HTTP_POST_VARS['dbServer'];
$dbUsername=$HTTP_POST_VARS['dbUsername'];
$dbPassword=$HTTP_POST_VARS['dbPassword'];
$dbDatabase=$HTTP_POST_VARS['dbDatabase'];
$resultpage=$HTTP_POST_VARS['resultpage'];
$admin=$HTTP_POST_VARS['admin'];
$success=$HTTP_POST_VARS['success'];
$failure=$HTTP_POST_VARS['failure'];
$login=$HTTP_POST_VARS['login'];
$logout=$HTTP_POST_VARS['logout'];
$changepassword=$HTTP_POST_VARS['changepassword'];
$confirm=$HTTP_POST_VARS['confirm'];
$adminemail=$HTTP_POST_VARS['adminemail'];
$noDB=0;
if(!@mysql_connect($dbServer, $dbUsername, $dbPassword)){
	$noDB=1;
}elseif(!@mysql_select_db($dbDatabase)){
	if(!@mysql_query("create database `$dbDatabase`")){
		$noDB=2;
	}else{
		if(!@mysql_select_db($dbDatabase)){
			$noDB=2;

 

Here the write code

		// if connection is successful, save parameters into config.php
	if(!$fp=@fopen("./config.php", "w")){
		echo $divFormat."<div style=\"color: red;\">".$Translation["couldnt save config"]."</div></div><br>";
		echo $backHome;
		exit;
	}else{
		fwrite($fp, "<?php\n");
		fwrite($fp, "\t\$dbServer=\"$dbServer\";\n");
		fwrite($fp, "\t\$dbUsername=\"$dbUsername\";\n");
		fwrite($fp, "\t\$dbPassword=\"$dbPassword\";\n");
		fwrite($fp, "\t\$dbDatabase=\"$dbDatabase\";\n");
		fwrite($fp, "\t\$resultpage =\"$resultpage\";\n");
		fwrite($fp, "\t\$admin =\"$admin\";\n");
		fwrite($fp, "\t\$success =\"$success\";\n");
		fwrite($fp, "\t\$failure =\"$failure\";\n");
		fwrite($fp, "\t\$login =\"$login\";\n");
		fwrite($fp, "\t\$logout =\"$logout\";\n");
		fwrite($fp, "\t\$changepassword =\"$changepassword\";\n");
		fwrite($fp, "\t\$confirm =\"$confirm\";\n");
		fwrite($fp, "\t\$adminemail =\"$adminemail\";\n");
		fwrite($fp, "?>");
		fclose($fp);

When the setup.php is ran from the browser I have a form I enter data into to be written. If manualy change the config.php file by removing the \  around [\'HTTP_HOST\']} it seems to work fine
