Single-line comments preventing functions from running, multi-line comments do not cause issue, why?

Question

As soon as I try to add single-line comments (e.g // comment) it prevents any of the functions following the comment from running.

Yesterday, with the same code on the same server, this was not an issue, and as soon as I remove the comment the code runs perfectly.

The code also runs perfectly if I use multi-line comments instead (e.g /* comment */).

What I would like to ask is if anyone knows why this is happening and if there is anything I can do to stop the single-line comments from affecting my code?

Are there any settings that affect this?

Has anyone encountered this problem before?

Example:

<?php
    session_start();
    require_once('includes.php');
    page_header('Task List');
    page_navigation('tasklist.php', $dbh);
    echo 'Success -1';
    /* Comment */
    $stmt = $dbh->prepare("SELECT * FROM task WHERE user_id = ? ORDER BY priority           ASC");
    echo 'Success 0';
    // If the user is admin use the chosen client_id
    if($_SESSION['user']['user_id'] === '1'){
        $stmt->execute(array($_SESSION['client_id']));
        echo 'Success 1';
    }else{
        // Otherwise use the user's user_id
        $stmt->execute(array($_SESSION['user']['user_id']));
        echo 'Success 2';
    }?>

Success -1 and Success 0 are both echoed, but anything after the single-line // comment does not run. If I take the comment away, it runs and Success 1 is also echoed.

your file encoding could be messed up causing newline chars not to be recognized — DevZer0, Aug 17 '13 at 12:37
It really depends on where you add that comment. Without a bit of code and the error message one cannot answer this questions. — Sven, Aug 17 '13 at 12:39
@DevZer0, that sounds like it may be the issue, how would I fix it? — , Aug 17 '13 at 12:40

It seems that using FileZilla instead of the CPanel File Manager to upload my files has caused the issue. Thank-you @DevZer0, it seems it is an encoding issue. Thank-you to everyone else as well , I really appreciate the help! — , Aug 17 '13 at 13:07

// will comment the whole line So that whatever you are added in that line will become commented, but /**/ will only consider the content which will come under /* and */.So even if you have added anything after */ will not be considered as comment.

Unfortunately the affected code is on a new line so the // comment shouldn't be affecting it at all, which is why I am so confused! – Aug 17 '13 at 12:39

I'm not php programmer, but check your newline encoding in hex editor, may be your interpreter accepts \r\nnewlines, but your script has only \n or something like that.

new lines are \r\n not `/n` – DevZer0 Aug 17 '13 at 12:46
