ini file not being ready properly - php

Question

I keep getting this error:
Warning: mysql_connect(): Unknown MySQL server host 'elephant' (1) 4
My ini file is this:
[Database]
DBHostName = "localhost"
DatabaseName = "elephant"
DBUserName = "elephant"
DBPassword = "practice"
[Config]
ConfigTableName = "stage2_config"
Skin="purple"
My file that reads the ini file and gives the error is this on the line with the double bold stars. I have no idea what is going on here and why it says the host isn't localhost.
<?php
$gv_SystemTest = "<h2>system.php has been included</h2>";
$gv_SystemFileInfo = pathinfo(__FILE__);
$gv_SystemDirectory = $gv_SystemFileInfo['dirname'] . '/';
$gv_SystemINIpath = $gv_SystemDirectory . '';
$gv_SiteGlobals = parse_ini_file($gv_SystemINIpath . $_SERVER['WIA_SYSTEM_INI'], true);
function echoContent($p_ContentID) {
global $gv_SiteGlobals;
$fv_dbLink = mysql_connect($gv_SiteGlobals['Database']['DBHostName'],
$gv_SiteGlobals['Database']['DBUserName'],
$gv_SiteGlobals['Database']['DBPassword']);
**mysql_connect($gv_SiteGlobals['Database']['DatabaseName']);**
$fv_TheQuery = "select *from wia_content where content_id = $p_ContentID";

Answer 1

The function mysql_connect does not allow to select a database as you tried on this line.
mysql_connect($gv_SiteGlobals['Database']['DatabaseName']);
To connect and select a database, you need to use the function mysql_select_db in addition to mysql_connect.
$link = mysql_connect('host','username','password');
$selected = mysql_select_db('database_name', $link);

Answer 2

Dont use mysql use only mysqli or pdo
I think you want to select db
to select db you should be mysql_select_db()
mysql_select_db('foo', $link);
your error in this line
mysql_connect($gv_SiteGlobals['Database']['DatabaseName']);
it should be of the form
mysql_connect('localhost', 'mysql_user', 'mysql_password');
