php - Random Switch Statement Improvements? -

-

I am trying to improve my switch statement to make it more random. I am currently trying to make the profile random. Two profiles are displayed on the other side at the same time these profiles are on a slide show and when I load the faded web page every and every second in 2.5 seconds I do not have to show the same profile at the same time (both above and below) Fan Thank you in advance for any input you may have made two switch statements as follows: 

  & lt; div id = "slider" & gt; & Lt ;? In Php $ getSliderInfoQuery = "pst.state_id = select ps.state_id f_name, L_NAME, book_reviews left the city, zipcode, state_id, book_types, profile_photo, PROFILE_URL as pst.name, book_states join book_readers prt.rating ps left pst The prt.user_id = ps.user_id at the joining preset where promoted_reader = 1 is "ORDER"; $ Pickrow = mt_rand (1, 6); $ Pickrow = mt_rand (1, 6); Switch ($ Pickrock) {Case 1: Get Slider Enfe ... Case 4: $ getSliderInfoQuery. = "Profile_photo"; breakdown; case 5: $; "breakdown; getSliderInfoQuery. = "L_name DESC"; break; case 6: $ getSliderInfoQuery. = "city Diissi"; break; & lt; div id = "slider 2" & gt; & LT ;? Php $ getSliderInfoQuery = "pst.state_id = select the ps.state_id f_name, L_NAME, prt.user_id city, zipcode, state_id, book_types, profile_photo, PROFILE_URL as pst.name, joining book_readers prt.rating ps left book_states left pst preset join book_reviews = ps.user_id where promoted_reader = 1 by ORDER "; $ Pickrow = mt_rand (1, 6); switch ($ pickrow) {case 1: $ getSliderInfoQuery. = "F_name"; breakdown; case 2: $ getSliderInfoQuery. = "L_name"; breakdown; Case 3: $ getSliderInfoQuery. = " City "; breakage; Case 4: $ getSliderInfoQuery. =" Profile_photo "; breakdown; case 5: $ getSliderInfoQuery. =" City dessc "; breakage; case 6: $ getSliderInfoQuery. =" L_name DESC "; break; } $ SliderResult = mysql_query ($ getSliderInfoQuery);    
 
 
 You can use MySQL  ORDER BY RAND ()  Without your php switch can  
  $ getSliderInfoQuery = "f_name, L_NAME, city, zip code, state_id, book_types, profile_photo, PROFILE_URL as pst.name, joining prt.rating ps left selection book_readers book_states pst Pst.state_id => Ps.user_id at prt.user_id on left book_reviews at ps.state_id where promoted_reader = 1 command rand () LIMIT 2 ";    
 You want to add  LIMIT  to get the number of rows. Repeat the lines instead of creating a query again.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
