Php-framework-PHP array traversal sku attribute value pairing

{Code ...} 4 values:; because the key value is dynamic, therefore, an array traversal algorithm is required.

$ Skuattr = Array ('7' => Array ('6' => '22x33', '9' => '44x55 ',), '8' => Array ('12' => 'Big scale'), '9' => Array ('8' => 'metallic ', '13' => 'plastic ',), '16' => Array ('14' => 'Circular '));

Obtain 4 values.

The principle is to require Cartesian product. A simple example is written.

phpFunction combineDika ($ data) {$ result = array (); foreach (array_shift ($ data) as $ k => $ item) {$ result [] = array ($ k => $ item);} foreach ($ data as $ k => $ v) {$ result2 = []; foreach ($ result as $ k1 =>$ item1) {foreach ($ v as $ k2 =>$ item2) {$ temp = $ item1; $ temp [$ k2] = $ item2; $ result2 [] = $ temp ;}}$ result = $ result2;} return $ result ;} $ skuattr = Array ('7' => Array ('6' => '22x33', '9' => '44x55 ',), '8' => Array ('12' => 'Big scale'), '9' => Array ('8' => 'metallic ', '13' => 'plastic ',), '16' => Array ('14' => 'Circular'); $ a = combineDika ($ skuattr ); print_r ($ );
