请问如何输出这样的json ?
{
data = (
{
"article_url" = "/disease/item/1";
"create_time" = "2014-08-11 11:38:58";
"knowledge_id" = 1;
title = "\U6d4b\U8bd5\U9057\U4f20\U75c5\U5e931";
},
{
"article_url" = "/disease/item/3";
"create_time" = "2014-07-22 15:38:28";
"knowledge_id" = 3;
title = "\U6211\U7684\U9057\U4f20\U77e5\U8bc6";
}
);
errcode = 0;
errdesc = "";
}
其中 ,来源于表的数据
"article_url" = "/disease/item/1";
"create_time" = "2014-08-11 11:38:58";
"knowledge_id" = 1;
title = "\U6d4b\U8bd5\U9057\U4f20\U75c5\U5e931";
表的循环读取程序,
$i=0;
$listarr=array();
while($db->ROW())
{
$listarr[$i]["article_url"]=$ROW[article_url];
$listarr[$i]["create_time"]=$ROW[create_time];
$listarr[$i]["knowledge_id"]=$ROW[knowledge_id];
$listarr[$i]["titlee"]=$ROW[title];
$i++;
}
如何通过这段 while程序输出最上面的json ?
请大家帮看看。
回复讨论(解决方案)
上面是组装的吧,代码给的不全。 errcode = 0;
errdesc = ""; 这两个哪里来的?
你的表数组没有这个值 errcode = 0; errdesc = "";
你可以打印原数组看看
print_r($listarr);
这个是数组合并的。主要是这部分的内容
data = (
{
"article_url" = "/disease/item/1";
"create_time" = "2014-08-11 11:38:58";
"knowledge_id" = 1;
title = "\U6d4b\U8bd5\U9057\U4f20\U75c5\U5e931";
},
{
"article_url" = "/disease/item/3";
"create_time" = "2014-07-22 15:38:28";
"knowledge_id" = 3;
title = "\U6211\U7684\U9057\U4f20\U77e5\U8bc6";
}
);
json?有??的?法,我想你大概意思是
{ "data":[ { "article_url":"/disease/item/1", "create_time":"2014-08-11 11:38:58", "knowledge_id":"1", "title":"title1" }, { "article_url":"/disease/item/3", "create_time":"2014-08-11 11:38:58", "knowledge_id":"1", "title":"title3" } ], "errcode":"0", "errdesc":""}
/** Json数据格式化 * @param Mixed $data 数据 * @param String $indent 缩进字符,默认4个空格 * @return JSON */ function jsonFormat($data, $indent=null){ // 对数组中每个元素递归进行urlencode操作,保护中文字符 array_walk_recursive($data, 'jsonFormatProtect'); // json encode $data = json_encode($data); // 将urlencode的内容进行urldecode $data = urldecode($data); // 缩进处理 $ret = ''; $pos = 0; $length = strlen($data); $indent = isset($indent)? $indent : ' '; $newline = "\n"; $prevchar = ''; $outofquotes = true; for($i=0; $i<=$length; $i++){ $char = substr($data, $i, 1); if($char=='"' && $prevchar!='\\'){ $outofquotes = !$outofquotes; }elseif(($char=='}' || $char==']') && $outofquotes){ $ret .= $newline; $pos --; for($j=0; $j<$pos; $j++){ $ret .= $indent; } } $ret .= $char; if(($char==',' || $char=='{' || $char=='[') && $outofquotes){ $ret .= $newline; if($char=='{' || $char=='['){ $pos ++; } for($j=0; $j<$pos; $j++){ $ret .= $indent; } } $prevchar = $char; } return $ret; } /** 将数组元素进行urlencode * @param String $val */ function jsonFormatProtect(&$val){ if($val!==true && $val!==false && $val!==null){ $val = urlencode($val); } } header('content-type:application/json;charset=utf8'); $result = array( 'data' => array( array( 'article_url' => '/disease/item/1', 'create_time' => '2014-08-11 11:38:58', 'knowledge_id' => 1, 'title' => 'title1' ), array( 'article_url' => '/disease/item/3', 'create_time' => '2014-08-11 11:38:58', 'knowledge_id' => 1, 'title' => 'title3' ), ), 'errcode' => 0, 'errdesc' => '');echo jsonFormat($result);
如果不需要格式?,可以
echo jsonFormat($result);
改?
echo json_encode($result);
即可。
上面的function都可以不用了。
搞定,谢谢。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
