what is the correct use of implode

lupercal

Hi. I have the following code.

I wish to display the content of $result2 as a delimited string . When i run this i get the message

Warning : Bad arguments to implode() i. What am I doing wrong. I thought mysql_fetch_array returns an array. Whay cant I then use imploded on it.

$result2 = mysql_query('SELECT title, cat_id, parent from business_categories_hierachy WHERE parent ="'.$parent.'";');

$result2array = mysql_fetch_array($result2);

echo($result2array);

$comma_separated = implode(",", '$result2array'); 
echo "$comma_separated";

$array should be betwenn ' '

tserbis

$comma_separated = implode(",", $result2array);
echo $comma_separated;

Excuse me cosminb, where did you learn PHP? In an artclass?

The manual is 100% right.

This was cosminb's first answer before he changed it.
Just so you didn't think I was crazy.
