列表项继续在PHP中的下一行

Question

I am using a form to submit a list of items that I want to save to a config text file, but these list items should all be on the same line of the text file. Every time PHP breaks apart and puts the list items into the file, however, it automatically adds a new line before the </li> tag. Why? How do I prevent this.

CODE:

$pro = explode("
",$_POST["pro"]);
$proo = "<ul>";

for($index=0; $index<count($pro);$index++)
{
    $proo .= "<li>";
    $proo .= $pro[$index];
    $proo .= "</li>";
}

$proo .= "</ul>";

$proo = str_replace("
","",$proo);

Edit 1

If I echo $proo into the webpage, it looks like this:

<ul><li>List Item 1
</li><li>List Item 2
</li><li>List Item 3
</li><li>List Item 4
</li><li>List Item 5</li></ul>

Why are there line breaks before each </li>?

Somewhere in there, it's adding new lines...

Thanks!

I just had to add the following line:

$proo = str_replace("","",$proo);

For whatever reason, it was adding a return character. I don't know why still, but thanks for all your help.
