我是PHP中的新手(对于这个问题也是JSON),但我不确定/确信我拥有的json数据的格式。我将一个MySQL为JSON用于其他应用程序,而我得到的格式如下:PHP Json对数组进行编码
[
{
"category":
{
"catId":"1",
"categoryName":"BABY FOOD",
"categoryNotes":"ONLY baby food varieties which have been listed below should be used. However if your doctor or pediatrician requires a specific diet please contact your Rabbi for further advice."
}
},
{
"category":
{
"catId":"2",
"categoryName":"BAKING INGREDIENTS",
"categoryNotes":""
}
},
{
"category":
{
"catId":"131",
"categoryName":"BEER",
"categoryNotes":"See Alcoholic Drinks"
}
},
{
"category":
{
"catId":"4",
"categoryName":"BEVERAGES - Powdered",
"categoryNotes":""
}
},
{
"category":
{
"catId":"5",
"categoryName":"BISCUITS",
"categoryNotes":"Locally produced biscuits usually contain fats, oils or improvers of non-kosher origin. There is a very large range of Israeli, South African and American kosher biscuits available locally. Even these imported biscuits and crackers (including Israeli produced goods) should only be used if marked with a reliable Rabbinic Hechsher. A 'K' on the packet alone is insufficient. Please note which products are dairy or pareve."
}
},
{
"category":
{
"catId":"6",
"categoryName":"BREAD AND BAKERY GOODS",
"categoryNotes":"Bread usually contains or comes in contact with Non-Kosher oils, fats or improvers and cannot be accepted as kosher without thorough investigation and subsequent authorisation"
}
},
{
"category":
{
"catId":"7",
"categoryName":"BREAD\/CORN\/RICE CRUMBS",
"categoryNotes":""
}
},
{
"category":
{
"catId":"8",
"categoryName":"BUTTER AND DAIRY BLENDS",
"categoryNotes":"Soft butters, butter spreads & dairy blends are NOT ACCEPTABLE unless specifically listed. Butter made from whey cream is NOT ACCEPTABLE unless produced under Rabbinic supervision"
}
},
{
"category":
{
"catId":"9",
"categoryName":"BUTTERMILK and LEBEN ",
"categoryNotes":""
}
},
{
"category":
{
"catId":"10",
"categoryName":"CAKES & CAKE SHOPS",
"categoryNotes":"Cakes and cake mixes usually contain Non-Kosher ingredients, and must only be used if they are produced under supervision <br\/> Cakes bought in a Non-Kosher cake shop, even if containing only kosher ingredients are NOT ACCEPTABLE because of the Non-Kosher utensils used in their preparation"
}
},
{
"category":
{
"catId":"11",
"categoryName":"CEREALS ",
"categoryNotes":""
}
},
...
]
等等。
现在,我不知道这是否是正确的格式,但我的代码来生成这个如下:根据我的代码
<?php
/* soak in the passed variable or set our own */
// $approved_prod_date = $_GET['date'];
$link = mysql_connect('localhost','root','broncos') or die('Cannot connect to the DB');
mysql_select_db('iKosher',$link) or die('Cannot select the DB');
/* grab the categories from the db */
$query= "SELECT c.id as catId, c.name as categoryName, c.notes as categoryNotes
FROM cat c
WHERE 1=1\n";
if(isset($_GET['catid']) && intval($_GET['catid'])) {
$query.="AND c.id = ";
$query.= $_GET['catid'];
}
if(isset($_GET['startIndex']) && intval($_GET['startIndex'])) {
if(isset($_GET['numItems']) && intval($_GET['numItems'])) {
$query .= "\nLIMIT ";
$query .= $_GET['startIndex'];
$query .= ",";
$query .= $_GET['numItems'];
}
}
// $query = "SELECT post_title, guid FROM wp_posts WHERE post_author = $user_id AND post_status = 'publish' ORDER BY ID DESC LIMIT $number_of_posts";
$result = mysql_query($query,$link) or die('Errant query: '.$query);
$num=mysql_numrows($result);
/* create one master array of the records */
$categories = array();
if($num) {
while($category = mysql_fetch_assoc($result)) {
$categories[] = array('category'=>$category);
}
}
header('Content-type: application/json');
echo json_encode($categories);
?>
,我这样做对吗?数组是否正确转换为JSON?
我已经做到了这之前,它显示有效的,只是我已经感觉这个JSON是不正确无论如何。喜欢它应该有:[“类别”:{“catId”:“1”,“...而不是[{”类别“:{”catId“:”1“,”c – Doz 2011-03-05 10:29:02
这是因为你的$类别是关联数组数组,并且在你的while循环中,你说“category”是包含catId,categoryName等的数组的关键。 – 2011-03-05 10:34:21
扩展了解决上述注释的答案。 – 2011-03-05 10:40:40
