thinkphp截取字符串函数无法显示省略号怎么解决?
来源: 互联网 发布时间:2014-08-30
本文导语: 对于thinkphp的截取字符串函数无法显示省略号的情况,可以参考如下解决方法: 打开common/extend.php页面,修改msubstr函数为: 代码示例: function msubstr($str, $start=0, $length, $charset="utf-8", $suffix=true) { if(function_exists("mb_substr")) { ...

代码示例:
function msubstr($str, $start=0, $length, $charset="utf-8", $suffix=true)
{
if(function_exists("mb_substr")) {
if($suffix)
{
if($str==mb_substr($str, $start, $length, $charset))
{
return mb_substr($str, $start, $length, $charset);
}
else
{
return mb_substr($str, $start, $length, $charset)."...";
}
} // www.
else
{
return mb_substr($str, $start, $length, $charset);
}
}
elseif(function_exists('iconv_substr')) {
if($suffix)
{
if($str==iconv_substr($str,$start,$length,$charset))
{
return iconv_substr($str,$start,$length,$charset);
}
else
{
return iconv_substr($str,$start,$length,$charset)."...";
}
}
else
{
return iconv_substr($str,$start,$length,$charset);
}
}
$re['utf-8'] = "/[x01-x7f]|[xc2-xdf][x80-xbf]|[xe0-xef][x80-xbf]{2}|[xf0-xff][x80-xbf]{3}/";
$re['gb2312'] = "/[x01-x7f]|[xb0-xf7][xa0-xfe]/";
$re['gbk'] = "/[x01-x7f]|[x81-xfe][x40-xfe]/";
$re['big5'] = "/[x01-x7f]|[x81-xfe]([x40-x7e]|xa1-xfe])/";
preg_match_all($re[$charset], $str, $match);
$slice = join("",array_slice($match[0], $start, $length));
if($suffix) return $slice."…";
return $slice;
}
{
if(function_exists("mb_substr")) {
if($suffix)
{
if($str==mb_substr($str, $start, $length, $charset))
{
return mb_substr($str, $start, $length, $charset);

}
$re['utf-8'] = "/[x01-x7f]|[xc2-xdf][x80-xbf]|[xe0-xef][x80-xbf]{2}|[xf0-xff][x80-xbf]{3}/";
$re['gb2312'] = "/[x01-x7f]|[xb0-xf7][xa0-xfe]/";
$re['gbk'] = "/[x01-x7f]|[x81-xfe][x40-xfe]/";
$re['big5'] = "/[x01-x7f]|[x81-xfe]([x40-x7e]|xa1-xfe])/";
preg_match_all($re[$charset], $str, $match);
$slice = join("",array_slice($match[0], $start, $length));
if($suffix) return $slice."…";
return $slice;
}
使用以上函数在截取字符串时,就可以显示省略号了,大家可以测试下看看效果如何。
