In actual application, when there are Chinese characters, when using json_encode() directly Function will encode the Chinese characters into the form of "\u***", since php5 This problem has been solved since .4. Use the following method to solve the problem of Chinese characters being encoded. json_encode("Chinese", JSON_UNESCAPED_UNICODE)
For example: 'Xu' becomes '\u80e5' after json_encode processing, and the final The Chinese part of json is replaced with unicode encoding. What we have to solve is to convert object to json and ensure that the Chinese inside the object still appears as normal Chinese in json. Now it seems that only using json_encode cannot achieve the goal.
My solution: first url encode (urlencode) the Chinese field in the class, then json encode (jsonencode) the object, and finally url decode (urldecode) json, which is the final json, and the Chinese inside is still the same It's the Chinese one!
The test code is as follows:
<?php class myClass { public $item1 = 1; public $item2 = '中文'; function to_json() { //url编码,避免json_encode将中文转为unicode $this->item2 = urlencode($this->item2); $str_json = json_encode($this); //url解码,转完json后将各属性返回,确保对象属性不变 $this->item2 = urldecode($this->item2); return urldecode($str_json); } } $c = new myClass(); echo json_encode($c); echo '<br/>'; echo $c->to_json(); echo '<br/>'; echo json_encode($c); echo '<br/>'; echo json_encode('胥'); ?>
Program output result:
{"item1":1,"item2":"\u4e2d\u6587"} {"item1":1,"item2":"中文"} {"item1":1,"item2":"\u4e2d\u6587"} "\u80e5"

foreach不是es6的方法。foreach是es3中一个遍历数组的方法,可以调用数组的每个元素,并将元素传给回调函数进行处理,语法“array.forEach(function(当前元素,索引,数组){...})”;该方法不处理空数组。
