Preg Match All - IP Range

preg match

[Go3Team]

I'm trying to perfrom a preg match all on the results of a whois search. Basically find "123.456.789.0 - 123.546.789.0" in the results.

I've tried a few ways to do it, but keep failing:

preg_match("/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})\s[-]\s(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/", $lines[$i], $y)

Can anyone point me in the right direction?

Thanks.

Something like this is closer:

preg_match("/123\.(4¦5)(4¦5)6\.789\.\d{3}/", $lines[$i], $y);

Depending on the exact range, you might need to adjust the above and will need to replace the broken bar ¦ with a bar... The bar means 'or' so the above matches:

123. followed by 4 or 5 followed by 4 or 5 followed by 6. followed by 789. followed by 'Any Three Numbers'

The IPs are variable, this finally worked for me:

preg_match("/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\s-\s\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/", $lines[$i], $y)
