Can't seem to remove extra whitespace in php or javascript

Question

I'm having a small problem. I have some php code which gets a string stored in a database as favoritegamelist, and in the database, it doesn't appear to have any extra white space. However when I try to echo the string out it generates a bunch of new line characters. I used javascript to get the character code of the characters creating space and it was 10 and that's new line?

Either way, I figured a preg_replace function would work, or maybe trim? So I tried trim, to no avail. Currently I have this code:

$gamelist = preg_replace('/[\x00-\x1F\x80-\x9F]/u', '', $row['favoritegamelist']);
echo $gamelist;

After this code executes, some javascript runs and collects the echo, then I log it to the console and this is where I see a ton of extra white space and I'm just stuck trying to get rid of it. The javascript code is here:

var mygames = document.getElementById("favoriteGamesDiv").innerHTML;
console.log(mygames);

favoriteGamesDiv is the area that the echo statement in php is applicable. And finally the console log that I get is:

        Llamas in Distress,Bow Master Halloween,Squary,

With all that extra space... So I'm not sure what to do. Any help would be appreciated ^-^ Thanks for bearing with me

Your favoriteGamesDiv probably has some format newlines/padding. So if you get the innerHTML, you will get all the whitespace as well. — Ivar

Also you can use below for javascript : myStr = myStr.replace(/\s{2,}/g,' ');

Using the trim of both PHP and JavaScript you can did what you want to do. Replace the $str with your real variable.

PHP

$str="                                Llamas in Distress,Bow Master Halloween,Squery, ";
echo trim($str);

Online Example

JavaScript

var str = "                                Llamas in Distress,Bow Master Halloween,Squery, ";
console.log(str.trim());

Online Example

Let me know if anything else I can do for you.

I didn't solve the problem with trim or preg_replace in either language, however I ran it through a javascript function that I made to substring the values out if the charcode was from 0-31... Thanks guys =)

Trimming array values with trim()

     <?php function trim_value(&$value) 
     { 
           $value = trim($value); 
      }

  $fruit = array('apple','banana ', ' cranberry ');
 var_dump($fruit);

       array_walk($fruit, 'trim_value');
     var_dump($fruit);

   ?>
