Question

how can I parse php array like this:

$cars= array(
    "Ford"=>array("C-Max"=>array("length"=>"4333","width"=>"1825","height"=>"1560"),"Escape"=>array("length"=>"4480","width"=>"1845","height"=>"1730")
    ,"Explorer"=>array("length"=>"4912","width"=>"1872","height"=>"1849"),"Fiesta"=>array("length"=>"3950","width"=>"1973","height"=>"1433")
    ,"Focus"=>array("length"=>"4488","width"=>"1840","height"=>"1497"),"Fusion"=>array("length"=>"4013","width"=>"1724","height"=>"1543")
    ,"Galaxy"=>array("length"=>"4820","width"=>"1854","height"=>"1723"),"Kuga"=>array("length"=>"4443","width"=>"1842","height"=>"1677")
    ,"Mondeo"=>array("length"=>"4844","width"=>"1886","height"=>"1500"),"Ranger"=>array("length"=>"5075","width"=>"1805","height"=>"1745")
    ,"S-Max"=>array("length"=>"4768","width"=>"1854","height"=>"1658"),
    "Hummer"=>array("H2"=>array("length"=>"5170","width"=>"2063","height"=>"2012"),"H3"=>array("length"=>"4782","width"=>"1989","height"=>"1872")));

to insert into MySQL table like this:

CREATE TABLE IF NOT EXISTS `cars_dimensions` (
  `id` int(10) NOT NULL auto_increment,
  `brand` varchar(120) character set utf8 NOT NULL,
  `model` varchar(120) character set utf8 NOT NULL,
  `length` varchar(5) character set utf8 NOT NULL,
  `width` varchar(5) character set utf8 NOT NULL,
  `height` varchar(5) character set utf8 NOT NULL,
  KEY `id` (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ;

When I use foreach and like $cars["Hummer"]["H2"]["length"]; I somehow can’t get another array dimension and cache the actual brand/model at the same time… Tho, my actual array is about 3000 items in the first dimension (brands).

You need two loops, one for the brands and one for their models:

foreach ($cars as $brand => $models) {
    foreach ($models as $model => $specs) {
        $query = "INSERT INTO cars_demensions (brand, model, length, weight, height)
                  VALUES ('$brand', '$model', {$specs['length']}, {$specs['width']}, {$specs['height']});";
    }
}
