複製程式碼程式碼如下:
function get_word($string, $length, $dot = '..',$charset='gbk') {
if(strlen($string) 返回$string;
}
$string = str_replace(array(''), array('','','&', '"' , ''), $string);
$strcut = '';
if(strtolower($charset) == 'utf-8') {
$n = $tn = $noc = 0;
while($n $t = ord($string[$n]);
if($t == 9 || $t == 10 || (32 $tn = 1; $n++; $noc++;
} elseif(194 $tn = 2; $n += 2; $noc += 2;
} elseif(224 $tn = 3; $n += 3; $noc += 2;
} elseif(240 $tn = 4; $n += 4; $noc += 2;
} elseif(248 $tn = 5; $n += 5; $noc += 2;
} elseif($t == 252 || $t == 253) {
$tn = 6; $n += 6; $noc += 2;
} 其他 {
$n++;
}
if($noc >= $length) {
break;
}
}
if($noc > $length) {
$n -= $tn;
}
$strcut = substr($string, 0, $n);
} else {
for($i = 0; $i $strcut .= ord($string[$i]) >; 127?
}
}
return $strcut.$dot;
}
$str = "歡迎參觀簡明 nowamagic";
$str_result = get_word($str, 12);
echo $str_result;
