使用json_encode的时候,中文会被转码成为unicode格式,解决这个问题,主要有以下三种方法:

1.

<?php
echo json_encode("叨嘛",JSON_UNESCAPED_UNICODE);
Copy after login

2.
<?php
$array = array(&#39;doma&#39; => urlencode("叨嘛"));
$array = json_encode($array);
echo urldecode($array);
Copy after login

3.
<?php
$string = 'result: {"errorcode":"1","errormsg":"\u65b0\u589e\u5931\u8d25\uff01","result":""}';
function unicode($str, $encoding = null) {
	return preg_replace_callback ( '/\\\\u([0-9a-fA-F]{4})/u', create_function ( '$matches', 'return mb_convert_encoding(pack("H*", $matches[1]), "utf-8", "UTF-16BE");' ), $str );
}
echo unicode ( $string );
Copy after login

第三种方式是在读取的时候对unicode编码进行转码

不理解的地方:为什么正则表达式是这样写的?\\\\如何解释,无法匹配呀
