array and trim

[graziano]

Hello ,

I have a problem ...

I have a file (users.txt) which contains user , password and number of user data similiar to this ;

file : users.txt

usera werwero 1
userb ysdkdfisd 2
userc sdfsdfdfd 3
userd ewrwerrr 4
usere rwerrrrrw 5
userf werreww 6

I created a file to create a webform which shows
all the users on file users.txt . The problem
is that is showing the user and the password and the usernumber while I need to extract only the users...

This is the code I am using...

$data_file = "/home/$usercp/users.txt";
if (!empty($HTTP_POST_VARS['is_sent'])) process_form();
print "<br><form action=\"killuser.php\" method=\"POST\" ";
$data = file($data_file);
$count = count($data);
$pos = 0; 

for ($x = 0; $x < $count; $x++)
{
   $data[$x] = trim($data[$x]); 
   if (!empty($data[$x]))
   {
print "<input type=\"radio\" name=\"data\"  value=\"$data[$x]\">\n"; 
print "<b>$data[$x]</b><br>";      

   }
}
print "<input type=\"submit\" value=\"SUBMIT" >\n";
print "</form>\n";

I wish to show only the user . The problem should be
here

$data[$x] = trim($data[$x]) 

it extracts the user and the password .
I am trying to extract only the user but I was not successfull ..

Any idea ?

Thank you

I tried to add

$data[$x] = explode(" ", $data[$x]);

just after

$data[$x] = trim($data[$x]);

but it returns "array" ...

Hi,

then try following:

$p = explode(" ", $data[$x]);
$user = $p[0];

Hi

See u have used
$file = file($filename);

First do print_r($file) and u will now the problem

Actually $file is now a array with each line as the value

Now u should actually do this

$file = @file($filename);

foreach ($file as $key=> $vals){
$linearr = @explode(" ",$vals);
echo "<p>Username -- ".$linearr[1],"</p>";
}

Feel free to contact me for more help.
