First entry in userslist (users.txt) won't work for login

[Olmancketslat]

Problem description:
When using file for reading files in php first read line will have a wrong string count.

Debug output:
$userliste:|a:5:{i:0;s:14:"andrea|1234";i:1;s:7:"abc|abc";i:2;s:7:"aaa|aaa";}
Note the s:14 for the first line even though andrea|1234 has only 11 chars.
String length for all other elements is ok.

Problem fixes:
