Corona SDK：将本地的Sqlite数据库转换为Json字符串，然后使用Php添加到数据库中。

我有一个像这样的lua文件：

display.setStatusBar( display.HiddenStatusBar )

-- Add onscreen text
local label1 = display.newText( "SQLite demo", 20, 30, native.systemFontBold, 60 )
label1:setTextColor( 190, 190, 255 )
local label2 = display.newText( "Creates or opens a local database", 20, 100, native.systemFont, 40 )
label2:setTextColor( 190, 190, 255 )
local label3 = display.newText( "(Data is shown below)", 20, 140, native.systemFont, 40 )
label3:setTextColor( 255, 255, 190 )

--Include sqlite
require "sqlite3"
--Open data.db.  If the file doesn't exist it will be created
local path = system.pathForFile("data.db", system.DocumentsDirectory)
db = sqlite3.open( path )

--Handle the applicationExit event to close the db
local function onSystemEvent( event )
        if( event.type == "applicationExit" ) then
            db:close()
        end
end

--Setup the table if it doesn't exist
local tablesetup = [[CREATE TABLE IF NOT EXISTS test (content, content2);]]
print(tablesetup)
db:exec( tablesetup )

--Add rows with a auto index in 'id'. You don't need to specify a set of values because we're populating all of them
testvalue = {2}
local id = system.getInfo("deviceID")
testvalue[1] = id
local time_stamp = os.time()
testvalue[2] = time_stamp

local tablefill =[[INSERT INTO test VALUES (NULL, ']]..testvalue[1]..[[',']]..testvalue[2]..[['); ]]

db:exec( tablefill )

--print the sqlite version to the terminal
print( "version " .. sqlite3.version() )

--print all the table contents
for row in db:nrows("SELECT * FROM test") do
  local text = row.content.." "..row.content2
  local t = display.newText(text, 20, 160 + (60 * row.id), native.systemFont, 40)
  t:setTextColor(255,0,255)
end

--setup the system listener to catch applicationExit
Runtime:addEventListener( "system", onSystemEvent )

所有它所做的就是在本地sqlite数据库中存储设备的唯一ID和时间戳。我需要把这些信息放到一个json字符串中。我还有一个简单的本地主机数据库叫做“testdata”，有两个列：“id”和“time”。我需要把我的JSON字符串拿出来，使用一个PHP文件把信息插入到我的数据库中。

我没有任何PHP的经验，所以我找不到办法。

谢谢！
