  • populating the category and subcategory

    In my sql db I've got a table with a category and a subcategory.
    Now I want to extract all values and place them in a javascript file.

    The javascript file looks like this:
    parent_array['Audi'] = ['A3','A4','A5','A6','A8','Q5','Q7','S3','S4','S5','S6','S8','RS6'];
    parent_array['Dacia'] = ['Sandero','Logan'];
    parent_array['FIAT'] = ['Bravo','Punto','Grande Punto'];
    As you can see there are categories and subcategories in the javascript part.
    How can I retrieve my db categories and subcategories to place them in the javascript.

    I don't know which sql statement I should use, I got this part but don't know how to continue.

    $q = mysql_query("select * from mydb");

    if(!$q) {echo "A DB error occured, please try again later. Error: ". mysql_error();}else{
    while($nv=mysql_fetch_array($q)) {$valueFromDb = $nv['Category']; $valueFromDb2=$nv['Subcategory'];

    /* Do some stuff here */
