php smarty函数扩展

扩展函数放到 */Smarty/libs/plugins目录下，文件命名格式 modifier.xxxx.php,函数名格式function smarty_modifier_xxxx

中文截取 modifier.cn_truncate.php

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;

}
