SIMPLE QUESTION - LOOP THRU ARRAY

[jayfray84]

Hi there,

I have the following PHP code:

<?php

$books = array(
array("title"=>"Book Title 1", "author"=>"Author 1", "publisher"=>"Publisher 1"),
array("title"=>"Book Title 2", "author"=>"Author 2", "publisher"=>"Publisher 2"),
array("title"=>"Book Title 3", "author"=>"Author 3", "publisher"=>"Publisher 3"),
);

foreach ($books as $key => $value) {
echo "$key : $value<br>";
}

?>

I'm trying to loop through this code, but all it outputs is:

0: ARRAY
1: ARRAY
2: ARRAY

-- It's not even pulling the proper $keys and $values. It works when there's just ONE array -- but not with this multidimensional array.

Any ideas?

Thanks!
J

It's outputting the correct keys and values as far as I can see. $books is a numerically indexed array of arrays, and since you can't simply echo/print an array (well you can, but PHP will just say "Array" instead of throwing an error), your output is correct.

What were you expecting to happen? You're going to have to have to treat $value as an array (since it is) inside the foreach() loop and handle it accordingly (e.g. use another foreach() loop on it if you desire).

EDIT: Also, welcome to PHPBuilder! When posting PHP code, please use the board's [noparse]

[/noparse] bbcode tags as they make your code much easier to read and analyze.
