Filter out duplicate records from log file

[bumbar]

Hallo!

I have this problem....

There is a log file with IP records.

The file looks like this:

log.txt
Failed password for root from 84.1.245.163
Failed password for root from 84.1.245.163
Failed password for root from 84.1.245.163
Failed password for root from 65.55.209.200
Failed password for root from 65.55.209.200
...
...
...

How can I do filter out duplicate IP address? And display result like this:

Failed password for root from 84.1.245.163
Failed password for root from 65.55.209.200

Thanks! 😃

Take a look at http://php.net/array_unique, which could be combined with a http://php.net/file_get_contents and an http://php.net/explode

That would be:
1) get the contents of log.txt
2) explode using the newline delimiter
3) use array_unique on the array from the explosion
