Php namespace - repeating Use in each class -

-

I sometimes have classes in subfolders that I am loading using this auto loader: < Pre> Spl_autoload_register (function ($ square) {$ class = str_replace ('\\', DIRECTORY_SEPARATOR, stroller ($ square)); if (file_exists (FILES_PATH.'classes /'.$ class'. Class.php ')) {Need_once (FILES_PATH.'classes/'.$ class'. Class.php')}}}}

So if I do new folder / subfolder \ Myclass, So this works.

The squares in folders are all in a namespace.

All of these sections The database class should be used, and here's the problem: when the class is in a namespace and the database finds the square, it can not be found.

(The DB class is in the global namespace) / P>

So I try to use "use BDD" (BDD is DB square) and it still does not work, because BDD is using PDO and therefore I am "bdd, pdo; Should use "; in every class of the project ... < P> I find this stupid. Is this normal? What's the better way to auto-load without using namespaces?

It is very easy:

If you are in the same name: < / P> 

  Namespace Foo;   
 All names in all classes are resolved relative to that namespace. Any  bar  will mean the class  foo bar , not the "global"  bar . If in any way, you do not want to reference the shape or form in the same name space, then  bar falcon  (class  Baz  namespace  bar ), You have two options:  
     
  1.  
     Use a fully qualified name for the class, such as:  
      \ Bar \ Baz   
     Where major  \  means that the name of the class will be resolved with the top namespace, not the current local, or   < Li> 
     If there is a problem in doing this every time If it is, use it  Surname :  
      Use Bar / Falcon;   
     which is a Macintosh for  
     ; Bar Baaz is used as a falcon;   
     Which means that you use " hawk " in this namespace, which means you have the class  bar , No  Foo \ Bar \ Baz .    
     Yes, it applies individually to each file if you want to cite  PDO  in some namespace in some file You must type "code"> PDO  to resolve this "global"  PDO  code> class or you  use the PDO  feature on top of the file To make aliases. How this named place works.  
     This applies to all use cases of any class name:  
      new \ PDO \ PDO :: staticMethod () \ PDO :: CONSTANT

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
