php - Extract whatever is in brackets using regular expressions -

-

I really do not understand regex, and it hurts my head.

I 

  blah blah blah (here i want to remove anything)   
 ... and I do not have PHP preg_split , Or equivalent, using the command, how to remove it, does not really understand.  
 How can I do this? And where is a good place to understand how it works?   
 
 
 Something like this should do the trick,  ( and ) What is the :  
  $ str = "blah blah blah (here i want to take a little away)"; If (preg_match ('/ \ (([^ \)] +) \' / ', $ str, $ matches) {var_dump ($ matches [1]); }   
 and you will get:  
  string 'Here is the bit that I want to remove' (length = 35)   
 
 Actually, the method I used to search for:  
     
  •  An opening  (; But as it does (special meaning, this To avoid:  \ (  
  •  One or more characters that are not closing brackets:  [^ \)] +  
       
    •  It is being captured, so we can use it later:  ([^ \)] +)   
    •  And this is the first  (and     
    •  A termination )    $ matches [1] > As available; Even here, it is a special character to save:  \)

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.

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)
