inserting file data into double array

[Amzul]

hello all,


i have a roblam that need some new view.

i have a file that contain ip | country

what i am tring to do is to know how many ips i have from each country.

the file looks like that :

34.34.34.34 | US
34.24.24.24 | US
12.12.12.12 | UK
10.10.10.10 | FR

my out put should say that i have
3 countrys (US,UK,FR)
and in US 2 ips: ip,ip.
in UK 1 ip: ip.
in FR 1 ip: ip.

i mange to create array with string index for all the countrys
but from here i am stock.

please help

here is a bit of code i done so far

<?php
$countrys = array();
$file  = "ip_list.txt";
$handle = @fopen($file,"r");
if ($handle) {
    while(!feof($handle)){
        $line = explode("|",fgets($handle, 4096));
        $countrys[$line[1]]=array();
    }
    echo count($countrys);
    print_r($countrys);
?>

what i need to do now the way i see it is to
go over the file agian and

if $line[1] == string_index          //US==US 
then country["US"][0]= 34.34.34.34

how can it be done?

No, you only read the file once. Then you build an array with the country as key and the sub-array holding the ip addresses.
When done reading, you just walk the array using 'foreach' and print out the contents of the array. Like this[php]<?php
$countrys = array();
$file = "test.txt";
$handle = fopen($file,"r");
if ($handle) {
while(!feof($handle)){
$line = explode("|",fgets($handle, 4096));
$countrys[trim($line[1])][]=$line[0];
}
echo count($countrys);
echo '<pre>';print_r($countrys);
foreach($countrys as $key => $arr) {
echo "<br>$key : ";
foreach ($arr as $ipad)
echo "$ipad ";
}
}
?>[/php]The output of your sample file will then be:

4
US : 34.34.34.34  34.24.24.24  
UK : 12.12.12.12  
FR : 10.10.10.10 

When you nhave any questions about this code, holler!
