解决php中对象使用json_encode转换后中文被编码为unicode
现象:众所周知使用json_encode可以方便快捷地将对象进行json编码,但是如果对象的属性中存在着中文,问题也就随之而来了。json_encode会将中文转换为unicode编码,例如:'胥'经过json_encode处理后变为'\u80e5',最终的json中中文部分被替换为unicode编码。我们要解决的就是将对象转换为json并保证对象内部的中文在json中仍然是以正常的中文出现,现在看来只使用json_encode是不能达到目的的。
我的解决方法:先将类中的中文字段进行url编码(urlencode),然后再对对象进行json编码(jsonencode),最后url解码(urldecode)json,即最终的json,里面的中文依旧是那个中文!
测试代码如下:
1 <?php <br /> 2 class myClass {<br> 3 public $item1 = 1;<br> 4 public $item2 = '中文';<br> 5 <br> 6 function to_json() {<br> 7 //url编码,避免json_encode将中文转为unicode<br> 8 $this->item2 = urlencode($this->item2);<br> 9 $str_json = json_encode($this);<br>10 //url解码,转完json后将各属性返回,确保对象属性不变<br>11 $this->item2 = urldecode($this->item2);<br>12 return urldecode($str_json);<br>13 }<br>14 }<br>15 <br>16 $c = new myClass();<br>17 echo json_encode($c);<br>18 echo '<br>';<br>19 echo $c->to_json();<br>20 echo '<br>';<br>21 echo json_encode($c);<br>22 echo '<br>';<br>23 echo json_encode('胥');<br>24 ?>
程序输出结果:
{"item1":1,"item2":"\u4e2d\u6587"}<br>{"item1":1,"item2":"中文"}<br>{"item1":1,"item2":"\u4e2d\u6587"}<br>"\u80e5"
