Utf-8 PHP to intercept strings in support of Utf-8

Intercept string
$string = "April 2006 I grew up one year old! ";
Echo substr ($string, 1). " ...";
Intercept string
function Substrgb ($in, $num)
{
$pos = 0;
$out = "";
while ($pos {
$c =substr ($in, $pos, 1);
if ($c = = "\ n") break;
if (Ord ($c) >128)
{
$out. = $c;
$pos + +;
$c =substr ($in, $pos, 1);
$out. = $c;
}
Else
{
$out. = $c;
}
$pos + +;
if ($pos >= $num) break;
}
return $out;
}
Echo Substrgb ($string, 8);
?>

The above describes the Utf-8 PHP intercept string support Utf-8, including the utf-8 aspect of the content, I hope the PHP tutorial interested in a friend helpful.
