para que en el preview (home) solo me muestre los primeros 200 carateres?
este es el codigo
Código PHP:
<?
$mostrar = 5;
$host = "localhost";
$user = "root";
$pass = "";
$dbname = "pruebas";
$conecta = mysql_connect($host,$user,$pass);
mysql_select_db($dbname,$conecta)or die("Error en conexion");
if ($n) {
$query = "select * from news where id='$n'";
$resp = mysql_query($query) ;
while ($datos = mysql_fetch_array($resp)) {
$fecha = date("d/m/Y",$datos[fecha]);
$titulo = strtoupper($datos[titulo]);
$noticia = nl2br($datos[noticia]);
$caracteres = strlen($datos[noticia]);
$preview = nl2br($datos[preview]);
echo "
<table width=\"524\" border=\"1\" cellpadding=\"0\" cellspacing=\"0\" bordercolor=\"#3A5695\" height=\"8\">

\n";
}
}else{
$query = "select * from news order by id desc";
$resp = mysql_query($query) or die("Error en consulta");
while ($datos = mysql_fetch_array($resp)) {
if ($mostrar > 0) {
$fecha = date("d/m/Y",$datos[fecha]);
$titulo = strtoupper($datos[titulo]);
