我尝试使用json_encoding大约两个小时,但我没有按要求获得输出.实际上这是移动应用程序开发人员要求的格式,我将在这里解释.下面的代码是我尝试过的:
include_once("class_connection.php");
//Getting the Parent Category
$sqlStr = mysql_query("select catname , id from `category` where `parentid`='0'");
$jsonArray = array();
while ($fetchStr = mysql_fetch_assoc($sqlStr)) {
$jsonArray[] = array("ParentCategory" => $fetchStr["catname"]);
$id = $fetchStr['id'];
//Getting child categories from the above parent
$sqlChildStr = mysql_query("SELECT catname,id,parentid FROM `category` where `parentid`='$id'");
while ($fetchchildStr = mysql_fetch_assoc($sqlChildStr)) {
$jsonArray[] = array("ChildCategory" => $fetchchildStr["catname"]);
}
}
echo json_encode(array("JsonOutput" => $jsonArray)) . "<br />";
输出是:
"JsonOutput":[{"ParentCategory":"Animals"},{"ChildCategory":"Bear"},{"ChildCategory":"Deer"},{"ChildCategory":"Dolphins"},
{"ParentCategory":"Art"},{"ChildCategory":"Hand Painting"},{"ChildCategory":"Painting"},{"ChildCategory":"3D"},{"ChildCategory":"Abstract"}]}
这里,在上面的输出中,父类别数组是空的,没有子类别数组.我想将所有子类别数组存储在其父类别数组中,最后我必须将父类和子类存储到JsonOutput数组中,所以我希望输出为
"JsonOutput":[{
"ParentCategory":"Animals" : [{
{"ChildCategory":"Bear"},{"ChildCategory":"Deer"},{"ChildCategory":"Dolphins"}
]}
"ParentCategory":"Arts" : [{ …我有以下结果
Array (
[0] => stdClass Object ( [name] => Identification )
[1] => stdClass Object ( [name] => Assay )
[2] => stdClass Object ( [name] => pH(Acidity/Alkalinity))
[3] => stdClass Object ( [name] => Sterility )
)
我想要的是使用逗号分隔对象数组值并返回为字符串,以便得到此结果:
Identification, Assay, ph(Acid/Alkalinity), Sterility
我尝试了以下内容
$data=(array)$result;
$answer=implode(",",$data);
这个回报:
Message: Object of class stdClass could not be converted to string
如何才能实现这一目标？
我想将脚本添加到 jquery mobile 中的外部页面而不是 home 文件（调用 jquery mobile 的源代码）。这是我的两个文件的代码
