Array to List

Hello,

Coming from ColdFusion, this is difficult. CF has an ArrayToList() function.
I can't find anything similar in PHP.

I'm building a list from an array with the following code, but it puts a
trailing "," and I need to remove it.

$campusList = "";
foreach ($_POST['campus'] as $campus_ID){
$campusList .= $campus_ID;
$campusList .= ",";
}
print($campusList);

I've tried this:
if($campusList <> ""){
$chr = ",";
$campusList = strrchr($campusList,$chr);
}

But it removes everything from the list, except 1 ","

Thanks,
James

implode();

$campusList = implode( ', ', $_POST['campus'] );

Simple as that.

Just need to truncate the last character:
$campusList = substr($campusList,0, -1);

> print($campusList);

Actually, I'm using $campusList for a SQL statement:

SELECT name FROM campuses WHERE inst_id IN ('$campusList');

It wasn't working until I found out that $campusList needs to look like
'1','2','3'.

$campusList = implode( ', ', $_POST['campus'] );

Returns 4,2,3 (whatever was selected)

I've looked in the manual on implode, but don't see how to surround each
value with single quotes. Is there another function that will do this?

Thanks,
James
