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 screen but I can not manipulate the results. 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"; -- Postgresql & php tutorials http://www.designmagick.com/
