Is it good to include unuse files?

[ngocviet]

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
