删除字符串中的空格并将其放在前面

High,

I'm using this function

function special_chars_replace($string){
    $result = preg_replace("/[&%\$#@'\*:\/\"\[\]\{\};\(\)\|\\\=!\^\?`~.,\+-]/", "", $string);
    return $result;
}

to delete all spaces in a css class name.

<?php echo special_chars_replace(strtolower(str_replace(" ","",$itemTags))); ?>

How do i preserve the first space before the name? So i can use it for a css class name. For example: class="tags tag01 tag02"

    Just add the space before you echo the string:

    <?php 
    echo " ".special_chars_replace(strtolower(str_replace(" ","",$itemTags)));
    ?>
