Now I have duplicate emails lists name

I have a TXT file with a list of emails Now I have duplicate emails lists name Example:

sami@woo.com
sds@woo.com
sami@woo.com
asfi@woo.com
sami@woo.com

I want to show me only once every mail

And the result:

sami@woo.com
sds@woo.com
asfi@woo.com

This code that I would love to get help:

<? Php

$ Username = $ argv [1];
$ File = file_get_contents (". / Emailist.txt");
$ Ex = explode ("\ r \ n", $ file);
for ($ i = 0; $ i <count ($ ex); $ i + +)
{
echo $ ex [$ i];
}
?>

You could load the file into an array, using the file() function -- it'll read the file, setting one item in the array for each line of the file.

And, then, use array_unique() on that array, to remove duplicates.

You'd have some code that looks like this, I suppose :

$list = file('./Emailist.txt');
$list_unique = array_unique($list);
foreach ($list_unique as $mail) {
    echo $mail;
}

You want to have a look at http://be.php.net/manual/en/function.array-unique.php

You can simply try this

$content = file('input.txt');
$result = array_unique($content);
print_r($result);

The following loads the file into an array, eliminates values and prints out the array.

<?php
  $file = array_unique(file('emails.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES));
  print_r($file);
?>
