Homephp教程php手册php中判断字符串是否全是中文或含有中文的实现代码

一,判断全是中文

复制代码 代码如下:


$str="'324是";
if(!eregi("[^\x80-\xff]","$str")){
echo "全是中文";
}else{
echo "不是";
}


二,判断含有中文

复制代码 代码如下:


$str = "中文";
if (preg_match("/[\x7f-\xff]/", $str)) {
echo "含有中文";
}else{
echo "没有中文";
}

$pattern = '/[^\x00-\x80]/';
if(preg_match($pattern,$str)){
echo "含有中文";
}else{
echo "没有中文";
}


我这几种方法都是在utf-8下面测试的,别的编码下没有测试过。
