I have been tearing out my hair to figure out a way to place array
values into $variables with not much luck. I can echo the array to the

I have searched wide and far all day on the web and I find nothing that
points the way how to extract values from an associative array and
assign them to a variable.
I expected to find some elegant way to do it. Here's the code that
outputs the values:
if ( isset( $book_categories[$bookID] ) ) {
foreach ( $book_categories[$bookID] AS $categoryID ) {
if ( isset( $category[$categoryID] ) ) {
echo($category[$categoryID]['category']);
}
}
}
Same as other variable assignment.
if ( isset( $category[$categoryID] ) ) {
$myvar = $category[$categoryID];
}
echo $myvar . "<br/>";
Doing it with a multi-dimensional array is no different to a result
set from a database or any other scenario.
I probably did not express myself clearly; I thought I did:
"place array * *values ** into * *$variables **"
Try this
$my_categories = array();
foreach (......) {
if (isset($category[$categoryID])) {
$my_categories[] = $category[$categoryID]['category'];
}
}
At the end, you can either:
foreach ($my_categories as $category_name) {
.. do something
}
or
$category_list = implode(',', $my_categories);
echo "The categories are ${category_list}\n";
