Class autoloading

[AdRock]

I have recently started using OOP for my old procedural code and I'm getting the hang of it.

 

The problem I have is with autoloading my class files.

 

I have this code on each of my pages I'm redoing.

 

require("php/classes/dbConstants.php");


function __autoload($className) {
$extensions = array(".php", ".class.php", ".inc");
$paths = explode(PATH_SEPARATOR, get_include_path());
$className = str_replace("_" , DIRECTORY_SEPARATOR, $className);
foreach ($paths as $path) {
$filename = $path . DIRECTORY_SEPARATOR . $className;
foreach ($extensions as $ext) {
if (is_readable($filename . $ext)) {
require_once $filename . $ext;
break;
  }
  }
}
}


try {
$forum = new Database(DBHOST, DBUSER, DBPASS, DBNAME);
}
catch (Exception $e) {
echo $e->getMessage(), "\n";
}

but i'm getting this error message

 

Fatal error: Class 'Database' not found in C:\www\newOB\news.php on line 21

 

 

The file with the autoloader is in the root and the database class is in a folder called php and in a subfolder called classes.

 

I need to adjust the path of where it's looking for my classes but no idea how

 

Can anyone please help?

No need to reinvent the wheel here IMO. Composer ships with a perfectly capable autoloader, use it.

I would choose a single naming convention for my class files.

Then I can.......

function __autoload($className) {

     include $path_to_class_directory . '/' . $className . '.class.php';
}

Anyways, You can (if you insist) .......

function __autoload($className) {
     $extensions = array(".php", ".class.php", ".inc");
     $paths = explode(PATH_SEPARATOR, get_include_path());
     
     # #########################################
     // ADD CLASSES DIR TO THE $paths ARRAY
     # #########################################
     $paths[] = '/documentRoot/php/classes';

     $className = str_replace("_" , DIRECTORY_SEPARATOR, $className);
     foreach ($paths as $path) {
         $filename = $path . DIRECTORY_SEPARATOR . $className;
         foreach ($extensions as $ext) {
              if (is_readable($filename . $ext)) {
                    require_once $filename . $ext;
                    break;
              }
         }
     }
}

Also a friendly tip, try to avoid using __autoload($class) unless you are developing a really small application, instead look for spl_autoload_register($loader).
