You can now customize the scope by the init method or the environment variable “IO4_WORKSPACE_SCOPE”.

IO4_WORKSPACE_SCOPE can have the values

• @cwd - current working directory - getcwd()
•  @www -   public www web directory - $_SERVER['DOCUMENT_ROOT']
• @global - USER HOME (Users HOME of current process or webspace) - the first directory in the cwd path wich is readable and writable by the current PHP process.
• @www@parent - the superior directory of  $_SERVER['DOCUMENT_ROOT']
• @www@root' -  the first directory in the $_SERVER['DOCUMENT_ROOT'] path wich is readable and writable by the current PHP process.
• custom directory - set a path/directory in IO4_WORKSPACE_SCOPE

Code from Webfat:

if(null === $scope){
 $scope = !empty(getenv('IO4_WORKSPACE_SCOPE')) ? getenv('IO4_WORKSPACE_SCOPE') : null;
}
    
switch($scope){
    case '@cwd' :
           $__home =  getcwd();
     break;        
    case '@www' :
           $__home =  $_SERVER['DOCUMENT_ROOT'];
     break;    
    case '@www@root' :
           $__home =  $getRootDir($_SERVER['DOCUMENT_ROOT']);
     break;    
    case '@www@parent' :
           $__home =  dirname($_SERVER['DOCUMENT_ROOT']);
     break;    
    case '@global' :
    case null :
           $__home = $HOME_DEFAULT;
      break;
    default :
          $__home = is_dir(getenv('IO4_WORKSPACE_SCOPE')) ? getenv('IO4_WORKSPACE_SCOPE') : $HOME_DEFAULT;
     break;
}
 

$__home = @is_readable($__home) && @is_writable($__home) ? $__home : $getRootDir($_SERVER['DOCUMENT_ROOT']);

$_ENV['FRDL_HOME'] = $__home;    
putenv('FRDL_HOME='.$_ENV['FRDL_HOME']);
