php - Modify every value of specified key in array -

-

I have a database with several rows and columns, which are caught with the PDO. 

  $ sql = "timestamp selection from table"; $ Stmt = $ dbh- & gt; Ready ($ sql); $ Result = $ stmt-> carry about; $ Result = $ stmt-> Get All (PDO :: FETCH_ASSOC);   
 One of the database columns is  timestamp  which is a 10 digit unix timestamp. I want to convert this server side to a readable format before sending the browser.  
 I want it to be formatted, but I know that it should be done on every line and this is where it travels me maybe a foreshop loop?    $ result ['timestamp'] = date ('h: i, ljsf of y', $ result ['timestamp']); Directly in DB is very easy to do this, because DB is already saving you to "start looping" on exact same data, to restart the client-side code:  
  SELECT DATE_FORMAT (timestamp, '% H:% i, etc ...') from the table

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
