PHP add elements to multidimensional array with array_push

Question

I have a multidimensional array $md_array and I want to add more elements to the sub-arrays recipe_type and cuisine coming from a loop that reads data from a table.

In the loop, I create a new table $newdata for each row:

$newdata =  array (           'wpseo_title' => 'test',           'wpseo_desc' => 'test',           'wpseo_metakey' => 'test'         ); 

and then, using array_push() I need to append the $newdata arrays to the following multidimensional array:

$md_array= array (      'recipe_type' =>        array (         18 =>          array (           'wpseo_title' => 'Salads',           'wpseo_desc' => 'Hundreads of recipes for Salads',           'wpseo_metakey' => ''         ),         19 =>          array (           'wpseo_title' => 'Main dishes',           'wpseo_desc' => 'Hundreads of recipes for Main dishes',           'wpseo_metakey' => ''         )       ),      'cuisine' =>        array (         22 =>          array (           'wpseo_title' => 'Italian',           'wpseo_desc' => 'Secrets from Sicily in a click',           'wpseo_metakey' => ''         ),         23 =>          array (           'wpseo_title' => 'Chinese',           'wpseo_desc' => 'Oriental dishes were never this easy to make',           'wpseo_metakey' => ''         ),         24 =>          array (           'wpseo_title' => 'Greek',           'wpseo_desc' => 'Traditional Greek flavors in easy to make recipies',           'wpseo_metakey' => ''         )       )      ); 

Whats the syntax for adding a new element (array) to the recipe_type array with array_push? I could never get my head around multidimensional arrays and I'm a bit confused.

Answer 1

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (       'wpseo_title' => 'test',       'wpseo_desc' => 'test',       'wpseo_metakey' => 'test'     );  // for recipe  $md_array["recipe_type"][] = $newdata;  //for cuisine   $md_array["cuisine"][] = $newdata; 

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);
