Question

I’m using TINYMCE text editor and if you use a double space the string gets cut off. So if I write:
a a a  a — it will output as — a a a — since there’s a double space after the third a. I tried:

$text = preg_replace('/[ ]+/', ' ', $text);

Which doesn’t work and I set:

<meta charset="UTF-8" />

This is sooo weird… what would cause this? Thank you
UPDATE

Here’s the code still not working…

jQuery / Ajax

    $('#page_left_comment_submit').click(function() {

        var comment = tinyMCE.activeEditor.getContent(); // This how you retrieve data with TINYMCE


        $.ajax({
            type: 'POST',
            url: '........',
            data: 'comment=' + comment,
            success: function(data) {
                $('#music_spot_comment_result_all_holder_top')..html(data);

                }
            });
        });

PHP

if(isset($_POST['comment'])) {
            $comment = $_POST['comment'];
            $comment = preg_replace('/\s+/', ' ', $comment);

            echo $comment;

            }

Var dump After
This is a a a (double space) a

string(9) "
a a a "

Before

Same string as above

string(9) "
a a a "

UPDATE
I’m doing this in the javascript to eliminate double spaces:

var comment = comment.replace(/ /g,'');

The regular expression for whitespace is \s.

In your case:

$text = preg_replace('/\s\s+/', ' ', $text);
