Please, I need a little help with PHP

Hi. I want to use the MixItUp script where I put the names category as filter. Basically, I need to achieve this:

<script type="text/javascript">
    $(function(){
        $('#Grid').mixitup({
            multiFilter: true,
            showOnLoad: 'category_1 category_2 category_3 category_4 category_5'        
        });
    });
</script>
 

I use this code for getting the names category pages but, it adds an space at the first  (generated by echo " " in order to separate the categories) that doesn't let to work correctly.

<script type="text/javascript">
    $(function(){
        $('#Grid').mixitup({
            multiFilter: true,
            showOnLoad: '<?php $categories = $pages->get("template=categories")->children("template=categories, sort=sort"); foreach($categories as $category){echo " ".$category->name;}?>'        
        });
    });
</script>
 

With the above code I get this:

<script type="text/javascript">
    $(function(){
        $('#Grid').mixitup({
            multiFilter: true,
            showOnLoad: ' category_1 category_2 category_3 category_4 category_5'        
        });
    });
</script>
 

Could somebody help me to avoid adding an space at the beginning of the first category?
Thanks in advance
Fernando

What about:

$i = 0;
foreach ($items as $item) 
{
    $i++;
    if ($i == 1)
    {
        // Do stuff the first item
    }
    else
    {
        // Do stuff the other items
    }
}

Thanks Arjen.

Finally, I used this code I found.

<?php
$resultstr = array();
$categorias = $pages->get("template=categorias")->children("template=categorias, sort=sort");
foreach ($categorias as $category) {
  $resultstr[] = $category->name;
}
$category = implode(" ",$resultstr);
?>

<script type="text/javascript">
    $(function(){
        $('#Grid').mixitup({
            multiFilter: true,
            showOnLoad: '<?php echo $category ?>'        
        });
    });
</script>
 

Surely, it can be optimized / improved, but it works
Thanks for your time

You could also use php's trim function to remove whitespaces of a string:

echo trim($categories);

Yes, it's much more efficient.
Thanks a lot!
