一、中文截?。簃b_substr()
mb_substr( $str, $start, $length, $encoding )
$str，需要截?cái)嗟淖址?
$start，截?cái)嚅_(kāi)始處，起始處為0
$length，要截取的字?jǐn)?shù)
$encoding，網(wǎng)頁(yè)編碼，如utf-8,GB2312,GBK
實(shí)例：
復(fù)制代碼 代碼如下:
$str='腳本之家：http://www.jb51.net';
echo mb_substr($str,0,4,'utf-8');//截取頭5個(gè)字，假定此代碼所在php文件的編碼為utf-8
?>
結(jié)果顯示：腳本之家
二、獲取中文長(zhǎng)度:mb_strlen()
mb_strlen( $str, $encoding )
$str，要計(jì)算長(zhǎng)度的字符串
$encoding，網(wǎng)頁(yè)編碼，如utf-8,GB2312,GBK
實(shí)例：
復(fù)制代碼 代碼如下:
$str='腳本之家：http://www.jb51.net';
echo mb_strlen($str,'utf-8');//假定此代碼所在php文件的編碼為utf-8
?>
結(jié)果顯示：24
