中文截取 modifier.cn_truncate.php

复制代码代码如下:

 
function smarty_modifier_cn_truncate($string, $strlen = 20, $etc = '...', 
$keep_first_style = false) 
{ 
$strlen = $strlen*2; 
$string = trim($string); 
if ( strlen($string) <= $strlen ) { 
return $string; 
} 
$str = strip_tags($string); 
$j = 0; 
for($i=0;$i<$strlen;$i++) { 
if(ord(substr($str,$i,1))>0xa0) $j++; 
} 
if($j%2!=0) $strlen++; 
$rstr=substr($str,0,$strlen); 
if (strlen($str)>$strlen ) {$rstr .= $etc;} 
if ( $keep_first_style == true && ereg('^<(.*)>$',$string) ) { 
if ( strlen($str) <= $strlen ) { 
return $string; 
} 
$start_pos = strpos($string,substr($str,0,4)); 
$end_pos = strpos($string,substr($str,-4)); 
$end_pos = $end_pos+4; 
$rstr = substr($string,0,$start_pos) . $rstr . substr($string,$end_pos,strlen($string)); 
} 
return $rstr; 
}

编码 modifier.unescape.php

复制代码代码如下:

 
function smarty_modifier_unescape($str) 
{ 
$str = rawurldecode($str); 
preg_match_all("/(?:%u.{4})|[^%]+/",$str,$r); 
$ar = $r[0]; 
foreach($ar as $k=>$v) { 
if(substr($v,0,2) == "%u" && strlen($v) == 6) 
$ar[$k] = iconv("UCS-2","GB2312",@pack("H4",substr($v,-4))); 
} 
return join("",$ar);
