I'm trying to extract ip address from an htaccess file. I can get the address when it's the full IP, but I'm having issues picking up the addresses when it's two or three octets.
It's looking for any line that starts with "deny from ".
I've tried the following with no luck.

Code: Select all

		$existingContent = file_get_contents(htaccess file);
		preg_match_all('/deny from \b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/', $existingContent, $matches);
		//preg_match_all('/^deny from (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})$/', $existingContent, $matches);
		//preg_match_all('/^deny from (\d{1,3}(?:\.\d{1,3}){1,3})$/', $existingContent, $matches);
		//preg_match_all('/deny from \d[\d.]*$/', $existingContent, $matches);
		$htaccessLines = $matches[0];

How can I fix this? Thanks.

preg_match_all('/deny from (\d{1,3}\.(?:\d{1,3}\.)?(?:\d{1,3}\.)?(?:\d{1,3})?(?:\/\d{1,2})?)/i', $existingContent, $matches);

Deny from 123.
Deny from 123.123.
Deny from 334.442.422.
Deny from 343.234.334.444
Deny from 123.334.0.0/16

array (
  0 => 
  array (
    0 => 'deny from 123.',
    1 => 'deny from 123.123.',
    2 => 'deny from 334.442.422.',
    3 => 'deny from 343.234.334.444',
    4 => 'deny from 123.334.0.0/16',
  ),
  1 => 
  array (
    0 => '123.',
    1 => '123.123.',
    2 => '334.442.422.',
    3 => '343.234.334.444',
    4 => '123.334.0.0/16',
  ),
)

I figure since it's for an extension I'm making for OC it would be appropriate to post it here since OC is all php code. No?

@nonnedelectari, that seems to work perfectly. Thanks.
