I have an interesting issue I have never seen before and it has me baffled. I have a script I wrote to produce an xml
document but its starting on line 2 instead of line 1 when it outputs, as if there is a whitespace and \cr before the string
is echo. I isolated the problem but it makes no sense to me, maybe you can figure it out.
here is the output:
line 1
line 2 <?xml version="1.0" encoding="UTF-8"?>
line 3... <feed xmlns="http://www.w3.org/2005/Atom" xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/"

I put in the line numbers so you can see the head starts on line 2 instead of line 1 so it is an invalid xml doc.
now here is what is causing it, and I used this simple script to find the code causing it.
<?
include_once ($try.php');
echo "line 1";
?>
here is the script causing it: (as try.php)
<?php
//*************** MAIN COFIG FILE *****************************************************
//*************** DO NOT EDIT BELOW ***************************************************
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler");
else ob_start();
$doc_root=$_SERVER['DOCUMENT_ROOT'];
//*************** EDIT DATABASE VALUES BELOW ******************************************
// main database
$db_user="";
$db_pass="";
$db_name="";
$db_host="";
//*************** DO NOT EDIT BELOW ***************************************************
include ($doc_root.'/core/system/config/config_values_inc.php');
function decrypt_user($encrypted_text,$skey,$iv2,$bit_check){
$cipher = mcrypt_module_open(MCRYPT_TRIPLEDES,'','ctr','');
mcrypt_generic_init($cipher, $skey, $iv2);
$decrypted = mdecrypt_generic($cipher,base64_decode($encrypted_text));
mcrypt_generic_deinit($cipher);
$last_char=substr($decrypted,-1);
for($i=0;$i<$bit_check-1; $i++){
if(chr($i)==$last_char){
$decrypted=substr($decrypted,0,strlen($decrypted)-$i);
break;
}
}
return $decrypted;
}
?>
** and the variables page that is causing the issue, if the include in the above script is commented out the problem goes
away and the output is at line 1 (config_values_inc.php)
<?php
// Config values includes
// core values
unset($a_values);
$page_name="config_values";
$con=mysql_connect($db_host,$db_user,$db_pass);
@mysql_select_db($db_name, $con) or die(mysql_error());
$values=mysql_query("SELECT pagename, content FROM wp_page WHERE pagename = '$page_name'");
$a_values = mysql_fetch_row($values);
@mysql_free_result($values);
unset($values);
mysql_close($con);
$array_val=urldecode($a_values[1]);
unset($config_values);
$config_values=explode('^',$array_val);
$domain_name=$config_values[1];
$advertise=$config_values[2];
$session_time=$config_values[3];
$tracking_code=$config_values[4];
$wpc=$config_values[5];

$a_values = mysql_fetch_row($values);

$options=explode(',',$array_val);
$template=$options[1];
$admin_title=$options[5];
$copyright=$options[6];
$page_title=$options[7];
$header_name=$options[8];
$page_desc_loc=$options[9];
// encryption keys
$key = "E4HD9y4DhSDjEmhhRemkS3N6";// 24 bit Key
$iv = "fYfhUeDm";// 8 bit IV
$iv2 = "ji50og6b";// 8 bit IV-2
$bit_check=8;// bit amount for diff algor.
// token key
$tokenkey=array

unset($a_values);
?>
What is causing this issue? There needs to be two pages like this because of editing options for the user… could it simply
be the include in try.php?
