Show current User picture and user details in custom block

step 1:) Create custom mudule..

function modulename_theme(){
return array(
    'article_node_form'=> array(
    
    'render element'=> 'form',
    
    'template'=> 'article_node_form'
    ),

);


}

function modulename_form_alter(&$form,&$form_state,$form_id)
{

print $form_id;

}

function searchform(){

global $user;

print_r($user);
$fid = $user->picture;
    $file = file_load($fid);
    if($file !=''){
    
    $printss  = theme('user_picture', array('account' => $user , 'path' => $file->uri,));
   //$title = theme('image_style', array('style_name' => 'thumbnail', 'path' => $file->uri,));
    //return ("hello Mr. ".$user->name.$user->picture);
    return ('Hello '.$user->name.'<br/>'.$printss.'<br/>'.$user->roles[2]);
}
}

And than call custom function " searchform()" in our custom block body.
