PHP Sequance Generator help needed

[amordeaa]

Hello every one i am pretty new to PHP and here is what i am trying to accomplish:

file1.csv has DECIMAL IP ADDRESSES range in the format of

"202353920","202353951"

"410129408","410129663"

"410150912","410151167"

"410178372","410178375"

"410178560","410178815"

I know how to read the numbers and place them in a text file by this code:

 

All i am looking for is a code to generate that range between the first 2 fields for example 202353920 202353921 202353922 till 951 and then we move to the next line and do the same.

I want the output to be to a file called range.txt.

$row = 1;

if (($handle = fopen("LONDON1.csv", "r")) !== FALSE) {

    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {

        $num = count($data);

        for ($c=0; $c < $num; $c++) {

            echo $data[$c].  "<br />\n";

           

        }

    }

 

this reads the all the fields .. but i dont know how to generate the sequance

 

 

 

Part #2 is to get all these numbers and convert them from decimals to x.x.x.x hostnames ( that part i figured out already ) by the this code:

function convert1($a){

        $b=array(0,0,0,0);

        $c = 16777216.0;

        $a += 0.0;

        for ($i = 0; $i < 4; $i++) {

                $k = (int) ($a / $c);

                $a -= $c * $k;

                $b[$i]= $k;

                $c /=256.0;

        };

        $d=join('.', $b);

        return($d);

}

 

But part #1 is where i am stuck ( to generate the numbers based on the given range.

any help would be really appreciated.
