Sorry for complicating things. I didn't read your request carefully enough.
YES, treat it as a string, and if you just need the last 2 digits,
just grab the substring:
php > $author = substr('2.00025',-2);
php > echo $author;
25

Storing data as a float is a bad idea. Way bad. Also, I think that's
too many significant digits for php to handle in a float.
You should store data in an accessible way. For instance, assuming
there are actually only two pieces of interesting data there, you
could store them as a hash:
php > $author = Array('account' => 25, 'response' => 2);
php > var_dump($author);
array(2) {
["account"]=>
int(25)
["response"]=>
int(2)
}
If that data is coming from somewhere beyond your control and is
presented as that, then parsing as a string will be the way to go.
Again, assuming there is no other useful information, a simple regexp
to parse it would be:
php > if (preg_match('/(\d+)\.0+(\d+)/','2.00025',$matches))
{
php { $author = Array('account' => $matches[2], 'response' => $matches[1]);
php { }
php > // else handle error if need be
php > var_dump($author);
array(2) {
["account"]=>
string(2) "25"
["response"]=>
string(1) "2"
}

Thank you for everyone's input. Someone suggested the MySQL list, so I posted my question there and got the answer I needed. Regards, Angela -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This task is not really suited for php. I would suggest looking into Ntop. It does exactly what you described.

[PHP] how to calculate how much data does each ip address use ?
Hello I have a freebsdbox firewall . also I have some internet customers. I want to save how much data they used in a table ( such as mysql table ) for each ip address. Apache2, php5 and mysql5.5 work on the box. How can I do it ? any script or tool. Thanks -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
