From your code:

			$id         = intval ($dynamic_line[0]);
			$dhtml      = intval ($dynamic_line[1]);
			$sub        = intval ($dynamic_line[2]);
			$sort       = intval ($dynamic_line[3]);
			$url        = $dynamic_line[4];
			$name       = $dynamic_line[5];
			$side       = intval ($dynamic_line[6]);
			$phras      = intval ($dynamic_line[7]);
			$break      = intval ($dynamic_line[8]);
			$usergroups = $dynamic_line[9];
			$hook       = $dynamic_line[10];

Whatever $break is, it's throwing off the index of the array. $usergroups is actually at position 8 according to your documentation:

0 ID: INT this ID must be unique
1 DHTML: INT 0 = normal / 1 = is DHTML
2 Sub: STR (ID) this means when it's a DHTML menue, the ID is the ID of the main link
3 Sort: INT a unique number inside each menu
4 URL: STR the link within
5 Name: STR name of the link
6 Side: INT 0 = left / 1 = right
7 Phrase: INT 0 = Text / 1 = Phrase
8 Usergroup: STR seperate primary Usergroupids by comma (leave blank for all)
9 Hook: STR
