Subject: making an array from data in textfile
OK, so I have this text file that holds a list of ip addresses like this:
127.0.0.1,127.0.0.1,127.0.0.1,127.0.0.1,127.0.0.1
Which are strings... You with me OK so far ?
Numeric [float] values only have 1 period.
There's no numeric datatype which has 3.
Currently, here is my code:
$file = 'ip.txt';
$fh = fopen($file, 'r');
$theData = fread($fh, filesize($file));
fclose($fh);
$ips = array($theData);
Since it's a numeric array,
No, it isn't. It's an array of strings which has numeric indices
(or keys depends what you call em)
I shouldn't need quotes around the ip octets.
Yes, you should : They're strings unless you use inet_pton to convert
them to numeric values.
When I try to echo certain parts of the array like:
echo $ips[0];
It's returning the whole array.
If you print_r($ips) you'll see the array structure (View -> Source
if you're looking at it in a browser).
My guess is your lines aren't terminated in \r\n, which PHP uses to
split the lines to array values.
You'll probably have to use some other method such as explode(',',
$ips) to break the individual comma separated entries into a set of
values. Other methods such as file_get_csv are generally more
efficient than reading line by line :

The text file is exactly like an array so it
shouldn't be a problem.
It's exactly like a CSV, from the example data you provided.
PS, please don't feel the need to prove it by posting the entire log file ;-)
Cheers - Neil
