php正则表达式 剔除字符串中的除了汉字的字符(只保留汉字)
1)utf-8的编码格式,匹配中文代码如下:
<?php
$str = "utf-8下匹配出中文字符串";
$preg = "/[\x{4e00}-\x{9fa5}]+/u";
if(preg_match_all($preg,$str,$matches)){
print_r($matches);
}
?>
2)gb2312的编码格式,匹配中文字符串代码如下:
<?php
$str = "gb2312下匹配出中文字符串";
$preg = "/([".chr(0xb0)."-".chr(0xf7)."][".chr(0xa1)."-".chr(0xfe)."])+/i";
if(preg_match($preg,$str,$matches)){
print_r($matches);
}
?>

$str = preg_replace('/[^\x{4e00}-\x{9fa5}]/u', '', $v); //"甜蜜世家"
//$v2 = "3东里屯250";
$result = explode('-',preg_replace('/[\x{4e00}-\x{9fa5}]+/u','-',$v));
$jl_order_num = $result[1];//商品数量
$jl_market_name = $str;//超市名称

php - 中文字符串分割
//先删除掉非中文的字体
$str = preg_replace('/[^\x{4e00}-\x{9fa5}]/u', '', $str);
//经过测试中文占3个篇幅
$re = chunk_split($str,3,",");
//再利用explode将字符串分割为数组 $re = explode(",",$re);
