Я получаю эти ошибки для каждого из них:

Warning: fopen(../top.txt) [function.fopen]: failed to open stream: No such file or directory

Warning: filesize() [function.filesize]: stat failed for ../top.txt

Warning: fread(): supplied argument is not a valid stream resource

Warning: fclose(): supplied argument is not a valid stream resource
