php in body -- missing something obvious -

-

My PHP is not PHPing, so tested simple ... something should be clear 

  & lt; Html & gt; & Lt; Top & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt ;? Php echo '& lt; Script language = \ "javascript \" & gt; Confirm ("are you seeing this?") & Lt; / Script & gt ;; '; ? & Gt; & Lt; / Body & gt; & Lt; / Html & gt;   
 In the code body, I get:  Confirm ("Are you seeing this?"); '; ? & Gt;   
 
 When I see "Source", I see:  
  & lt; Html & gt; & Lt; Top & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt ;? Php echo '& lt; Script language = \ "javascript \" & gt; Confirm ("are you seeing this?") & Lt; / Script & gt ;; '; ? & Gt; & Lt; / Body & gt; & Lt; / Html & gt;    
 
 
 What is the extension of your file? Running a webserver? How are you calling your php script?  
 Make sure there is a  .php  extension in it, the webserver is running, the file is under the Webroot directory and you can call it  Http: // localhosti / path / To / file.php   
 Also make sure that you can not escape quotation marks when not necessary,  echo & lt; Script type = "text / javascript" & gt; One ?? | & Lt; / Script & gt; ';  should work

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)
