Echo two $variables without space?

Question

I got a text file [list_of_files.txt] contaning list of files without extension e.g.

image_23.
image_24.
image_25.

I'm using POST method to add a single word to all of the lines e.g "jpg" and display the results:

image_23.jpg
image_24.jpg
image_25.jpg

The problem is that echo displays:

image_23. jpg
image_24. jpg
image_25. jpg

How i can remove spaces?

$files=file('list_of_files.txt');

    if ($_SERVER['REQUEST_METHOD'] == 'POST'){ 
        foreach($files as $list)
{
    $extension = $_POST['extension'];
    echo "$list",$exstension,"";
    echo "</div>";
}
 }else{ 
?>

note:echo "$list" is a pointless use of quotes. echo $list works just as well. — Marc B

That should read as echo "$list",$extension,""; and not exstension — Funk Forty Niner

Use trim to trim the white space.

$files=file('list_of_files.txt');

if ($_SERVER['REQUEST_METHOD'] == 'POST'){ 
    foreach($files as $list)
    {
        $extension = $_POST['extension'];
        echo trim($list) . trim($extension);
        echo "</div>";
    }
}else{ 
?>

Try this:

echo trim($list) . trim($extension);

<?php
$files = file('list_of_files.txt');
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    foreach($files as $list) {
        $ext = $_POST['extension'];
        $file = $list.$ext;
        echo $file;
    }
}
?>

This is a simple solution to it

echo $list.$extension;

You can make a trim() on $extension before to display it to be sure there is no space.
