1、截取GB2312中文字符串
$start = $start*2;

4、BugFree 字符截取函数
preg_match_all($pa, $string, $t_string);

< ?php
$tmpstr .= substr($str, $i, 2);
for($i=0; $i< $strlen; $i++)
?>

}
{
$tmpstr = '';
* @param int $Length the length of returned string.
}
/*
$I = $I + 3;
$strlen = strlen($string);
return $tmpstr;
@开始长度默认为 0
{
return preg_replace('#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$from.'}'.
}
供大家学习参考。

{
}
elseif( ord($StringTMP) >=192 )

* Return part of a string(Enhance the function substr())

$StringTMP = substr($String,$I,3);
$strlen = $start + $len;
$I = $I + 2;
}
$Length = "18";

复制代码 代码示例:

{
return $String;
if(strlen($tmpstr)< $strlen ) $tmpstr.= "...";
else
$StringLast[] = $StringTMP;
if (strlen($String) < = $Length )
{

复制代码 代码示例:
