First Generic Class
Well I've been wanting to get a generic class done for a while and I think I've finally finished one that covers the basics, and I'd like some input on which functions to optimize and the such...all help is appreciated
PHP Code:
<?
class core
{
//contains the main mysql abstraction layer
var $db;
//tags to be searched for
var $tags = array();
//all the replacement for the tags
var $reps = array();
//the neccesary site info
var $siteinfo = array();
//make a holding variable for out content
var $rcontent;
//the general content holder..
var $content;
//holds the session and cookie names
var $secinfo = array('cookie'=>'TlcFinalCMS','session'=>'TlcFinalCMSession');
//holds member data
var $member;
//holds language
var $language;
/*====================================================+
| The General Purpose functions
|=====================================================*/
//the constructor function
function core()
{
$this->db = NewTlcDB(DB_HOST,DB_USER,DB_PASS,DB_TABLE);
//determine the site info crap..
$this->siteinfo = $this->db->Execute("SELECT `url`,`title`,`skin`,`lan`,`defaultmod` FROM `site_config`");
$this->siteinfo = $this->siteinfo->fields;
//load the language file.
$this->LoadLanguage($this->siteinfo['lan']);
//build the tags array..
$this->tags = array(
'<[siteurl]>',
'<[skinurl]>',
'<[title]>',
'<[gentime]>',
'<[content]>',
'<[cmp(',
')]>'
);
//build all there replacements.
$this->reps = array(
$this->siteinfo['url'],
$this->siteinfo['url'] . 'template/' . $this->siteinfo['skin'],
'<?=$this->siteinfo[\'title\']; ?>',
'<?=$this->siteinfo[\'gentime\']; ?>',
