>I didn't say fseek() goes to the start of a line. I said that fgets() should read a whole line, no matter where the pointer is at. I've already managed to get the result I want by using file() as you've suggested and array_rand(), and the result is very good. I just need to figure out why when using fgets() with fseek() & rand(), the script returns partial strings form the city names.
