Php help

Hay folks a friend sent this to my its some sort of verifier for tublr
if user name is valid or not.
is there a way to modify so it opens up a txt file and tests many
thanks any help you give

<?php
$username = "hh";

$url="http://"$username".tumblr.com";

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_exec($ch);
$header = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

if( $header == "404" )
{
echo not found
}else{
echo valid
}

If your happy to make a MySQL database with all the usernames in then, sure I know how.
You would just set up a while look and test the connection for each row.

i have been messing around with this code
but not working iam sure theres a way for
php to load list to check

<?php
$file = fopen("test.txt","r");

//some code to be executed

fclose($file);
?>

but no luck at all

You will have to output whether the username is valid or not somewhere and it would be easier just adding a value to a database then editing a file tbh.

i see i never messed around with databases and such have to learn this could be my first time could you point me in the right way to setup MySQL database and files needed iam running on ubuntu at moment

Its relatively easy, you got cpanel with phpMyAdmin?

no dont have hosting i was going to run it from local
i will get hosting next week if thats what i will need
as iam sure it will be easyier with it host+cpanel

The last thing you want is to store usernames in a .TXT file. That's very insecure, your best chance would be to use a MySQL Database, helps a lot more than anything else.
