Question

I’m using this to to retrieve two columns in a database

   while($comment[]=mysql_fetch_array($sql));

this returns an array with associative and number indices for each column.
This works great but I would also like to create a new array from the orginial$comment[] that is just a simple array of strings (only the first column). What are my options? Is there any way to accomplish this without looping through a second time?

Depending on how many columns you have, you could do something like:

$result = mysql_query($sql);
while (list($col1[], $col2[]) = mysql_fetch_row($result));

$col1 will be an array of just column 1’s values, and $col2 will be similar for column 2’s values.
