what exactly is happening here?

[sean_paul]

foreach ($book_array as $row)
{
$url = "show_book.php?isbn=".($row["isbn"]);
echo "<tr><td>";

I'm talking about the line "show_book.php?isbn=.($row[isbn"]);

is the isbn being passed as a variable for "isbn" in "show_book.php?isbn.

That seems to make sense.

I need a second opinion

Thanks

Well this is what i see

$url = "show_book.php?isbn=".($row["isbn"]);

you are missing a " at the end before the ;

my question is why are u using .($row["isbn"]) you could simple use '"$row['isbn']"' but whatever works i guess

[Tewl]

Try

$url = "show_book.php?isbn=\".($row["isbn"])\"";

I took the code from a book and it works but I'm wonering what exactly is happening.

Reread my first post and if my statement is correct tell me so, please.

And why do I want to put an @ symbol in there?
Isn't that to suppress errors.

Thanks again

Oh, my bad been up too long waitin on a reply to my own post not reading correctly anymore lol. anyways from what I can tell $row is an array from a query where u have many results with the row isbn

the foreach loops goes through each result and checks the isbn row and sets it to $url

e.g.

say i did select * from table_name;

and i have 10 entries and i want to list the isbn for each entry

the loop you have would go through each row and echo the result for the isbn column

eh sorry im not really good at explaining just tryin to help out and kill some time
