汉字在php应用中经常会给我们带来一些麻烦,今天在网上找到一段array数组转换成xml时发现汉字就为空了,后来gg了关天得出比较好的结果了,下面与大家分享。

在 php 数组转xml我们在php中学会这样来写

 代码如下 复制代码


function array2xml($array, $xml = false){
    if($xml === false){
        $xml = new SimpleXMLElement('');
    }
    foreach($array as $key => $value){
        if(is_array($value)){
            array2xml($value, $xml->addChild($key));
        }else{
            $xml->addChild($key, $value);
        }
    }
    return $xml->asXML();
}
 
header('Content-type: text/xml');
print array2xml($array);

当内容出现汉字时会出现为空的情况


解决办法是转编码处理

 代码如下 复制代码

 
function array2xml($array, $xml = false){
    if($xml === false){
        $xml = new SimpleXMLElement('');
    }
    foreach($array as $key => $value){
        if(is_array($value)){
            array2xml($value, $xml->addChild($key));
        }else{
           
//$value=utf8_encode($value);
 
            if (preg_match("/([x81-xfe][x40-xfe])/", $value, $match)) {
                $value = iconv('gbk', 'utf-8', $value);  
//判断是否有汉字出现
            }
            $xml->addChild($key, $value);
        }
    }
    return $xml->asXML();
}

后面给大家另一些关于汉字正则实例

1.判断字符串是否全是汉字

 代码如下 复制代码

    $str = '全部是汉字测试';
    if (preg_match_all("/^([x81-xfe][x40-xfe])+$/", $str, $match)) {
        echo '全部是汉字'; 
    } else {
        echo '不全是汉字';
    }
?>

当$str = '全部是汉字测试'; 时输出"全部是汉字";
当$str = 'all全部是汉字测试'; 时输出"不全是汉字";
