$Text=preg_replace("/[url](http://.+"1",$Text);

$Text=preg_replace("/[url](.+"1",$Text);

$Text=preg_replace("/[url=(http://.+?)](.+"2",$Text);

$Text=preg_replace("/[url=(.+?)](.+"2",$Text);

$Text=preg_replace("/[color=(.+?)](.+","2",$Text);

$Text=preg_replace("/[font=(.+?)](.+","2",$Text);

$Text=preg_replace("/[email=(.+?)](.+","2",$Text);

$Text=preg_replace("/[email](.+","1",$Text);

$Text=preg_replace("/[i](.+"1",$Text);

$Text=preg_replace("/[u](.+"1",$Text);

$Text=preg_replace("/[b](.+"1",$Text);

$Text=preg_replace("/[fly](.+"1",$Text);

$Text=preg_replace("/[move](.+","1",$Text);

$Text=preg_replace("/[shadow=([#0-9a-z]{1,10}),([0-9]{1,3}),([0-9]{1,2})](.+?)[/shadow]/is","

return $Text; ",$Text);}}
