    Is it good to include unuse files?

    Sorry for the noob question!
    My project have alot class files(>100), in one request I only need some
    class(1-5), but I dont like to have to specifies needed files so I make
    a include.php, that include all my class files.

    In action file, I only include the include.php! Is it good for
    performent? Does it make any problem?

    Thanks!

      Including 100+ files while you only need 5 will always hurt your
      performance. Includes are slow.

      Even so, it shouldn't necessarily be a problem unless you run over the
      maximum execution time limit.
      Just keep in mind that users who have to wait a lot, may not stay for long.

          No, it is not good for performance, as has already been stated.

          The bright side is that you don't have to specify each include that you
          need to use seperately anymore. Have a look at autoload [1]. With
          this function, you tell php that whenever I want an ABC object, include
          the file class.ABC.php, or whatever naming convention you are using.
          This way, php only includes the files which are referenced in your
          code. Just define it in your include.php file and you'll never have to
          think about it again.
          *Disclaimer: PHP 5 only
