Remove last comma or prevent it from being printed at all MySQL/PHP

Question

I am printing a set of words that is placed in a MySQL database and I am retrieving it with PHP. I want to present it as a comma separated list, but I need it not to print or re

Answer 1

I usually do this by placing the results in an array first

$some_array = array();
while($row0 = mysql_fetch_array($result0, MYSQL_ASSOC)) {
   $some_array[] = $row0['LCASE(ord)'];
}

then simply:

echo "My List: " . implode(', ', $some_array);
// Output looks something like:
My List: ord1, ord2, ord3, ord4

Answer 2

I would do:

$keywords = array();
while($row0 = mysql_fetch_array($result0, MYSQL_ASSOC))
{
   $keywords[] = $row0['LCASE(ord)'];
}

echo implode(',', $keywords);

Answer 3

substr($string, 0, -1);

That removes the last character.
