I found that my PHP script throws an 500 (Internal Server Error) at the line which wp_generate_attachment_metadata function is used:

$attach_data = wp_generate_attachment_metadata( $attach_id, $fullpathfilename );

I can exit and take an output before this line but not after that.

I checked the inputs too:

Array
(
    [attach_id] => 101362
    [fullpathfilename] => /home/appleapp/USER/wp-content/uploads/2014/05/Beat-the-Boss-2-17+945428.png
)

Any help is really appreciated.

You might need to require once this file:

wp-admin/includes/image.php 

wp_generate_attachment_metadata() should be used in conjunction with wp_update_attachment_metadata(). So your code should look something like this. (quote from the codex).

To generate attachment metadata for attachment with parent post ID 37:

<?php
  $attach_id = wp_insert_attachment( $attachment, $filename, 37 );
  $attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
  wp_update_attachment_metadata( $attach_id,  $attach_data );
?>
