php - Comparing arrays, point me in the right direction please -

-

So what is trying to do, compare the orders in your database from the bank database and if they confirm the match status Mails

The transaction comes in an XML format 

  $ transaction-> User-number // This is the social security number of the person who transmits the transaction transactions - & gt; Amount // This is the transfer amount   
 I need to compare the user-number in the user-number associated with the order in my database. I would like to create two arrays with those numbers Use  array_intersect  to find those data that are present in both databases and transactions xml.  
 Now, I have to see the number of people who have done the transaction on their user-number, whether they have transferred the correct amount.  
 I will be able to finish it, but somehow I feel that using it is a simple solution in the form of an index in the form of a number and two arrays in the form of a user-number and value and Compare them.  
 Someone can help me here before writing some complex, slow and dirty code. / P> 
 thanks   
 
 
 Hopefully this will bring you the right path:  
  class commands {private $ user = null; Private $ emt = null; Public Function __construct ($ user, $ AMT) {$ this- & gt; User = $ user; $ This- & gt; AMT = $ AMT; } Public function getUser () {Return $ this- & gt; the user; } Public function equals ($ transactions) {if ($ -> this-> Users == $ Transaction-> Username & amp; amp; $ this-> AMT == $ Transaction-> Zodiac ) {truth; } return false; }} // An empty array to keep the entire order $ complete = array (); // Order a loop over the order ($ order as $ order) {// A new order object order order $ new order ($ order-> user, $ order- & gt; amount); // // // Loop on all Transactions Forex ($ Transaction as Transaction) // If the transaction is equal to our order, // add it to the complete order list ($ Order-> Equal ($ transactions)) {$ full [] = $ order; }}}   
 This creates a small wrapper class for all your orders, then allows you to compare the order of any transaction as you described it above is.  
 I hope this helps.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
