How to include() all PHP files from a directory?

Question

Very quick n00b question, in PHP can I include a directory of scripts.

i.e. Instead of:

include('classes/Class1.php');
include('classes/Class2.php');

is there something like:

include('classes/*');

Couldn't seem to find a good way of including a collection of about 10 sub-classes for a particular class.

Answer 1

I suggest you use a readdir() function and then loop and include the files (see the 1st example on that page).

Answer 2

If you are using php 5 you might want to use autoload instead.

Answer 3

foreach (glob("classes/*.php") as $filename)
{
    include $filename;
}

Answer 4

Here is the way I include lots of classes from several folders in PHP 5. This will only work if you have classes though.

/*Directories that contain classes*/
$classesDir = array (
    ROOT_DIR.'classses/',
    ROOT_DIR.'firephp/',
    ROOT_DIR.'includes/'
);
function __autoload($class_name) {
    global $classesDir;
    foreach ($classesDir as $directory) {
     if (file_exists($directory . $class_name . '.php')) {
      require_once ($directory . $class_name . '.php');
      return;
     }
    }
}
