adding strings together

[Anon]

How do I add a string together?

Example:

keywords[0]=ideas&keywords[1]=moreideas&keywords[2]=evenmoreideas

Here's a bit of code. The problem is I can't have the two strings side by side.

$kn = 0;

if ($keywords$kn !=(''))

do {} else {}

$kn++;

} while ($keywords[$kn] !=(''));

else {}

sorry, forget about the []s. I forgot to take them all out

Put a dot between the strings.

e.g.

$result = $string1 . $string2;

Mind you, I can't quite make out what your snippet of code is trying to do!

Sorry, I was trying to figure out an alternative to the [] which you answered in the previous post. I was figuring that it was that which was causing the illegal string error, but now I'm not so sure.

Is the following code allowed to you know. It's a form which updates multiple bids on keywords in one go or deletes them if the delete box is checked.

$kn = 0;

if ($keywords[$kn] !=(''))

do {
$time = date("Y-m-d H:i:s",time());
mysql_query ("UPDATE keywords SET bid='$bid[$kn]' WHERE keywords='$keywords[$kn]' and username='$username' and password='$password' and url='$url'");

if ($delete[$kn]==('on')){
mysql_query ("delete from keywords WHERE id='$id[$kn]' and username='$username' and password='$password'");
} else {}

$kn++;

} while ($keywords[$kn] !=(''));

else {}

The

else {}

need to go. There should never be a need to say "else do nothing". Just don't say anything in that case.
