如果不等于WordPress PHP但是如果大于

I have a WordPress site where I am trying to dynamically create a comma separated list of values using PHP. However all of my lists have a comma at the end when they shouldn't and I can't seem to work out how to remove it.

My current code is;

$tcount=count($terms);
foreach($terms as $term){
    echo $term->name;
    if($tcount>1){
        echo ', ';
    }
}

There is a comma at the end where it should simply be blank. I tried the following code instead but it didn't work;

$tcount=count($terms);
foreach($terms as $term){
    echo $term->name;
    if(!$tcount==$tcount && $tcount>1){
        echo ', ';
    }
}

Does anyone know what I'm doing wrong?

    Just trim the last comma:

    $result = "";
    
    $tcount=count($terms);
    foreach($terms as $term) {
      // save output in temporary variable...
      $result .= $term->name;
      $result .= ', ';
    }
    echo substr($result, 0, -2);  // delete last two characters (", ")
