How to Add Elements to Multidimensional Arrays Using PHP\'s array_push

Adding Elements to Multidimensional Array with PHP's array_push

Multidimensional arrays in PHP provide an efficient way to organize complex data. When working with these arrays, you may encounter the need to add new elements to sub-arrays. This is where PHP's array_push function comes in handy.

Adding Elements to Specific Sub-Arrays

To add an element to a specific sub-array, use the following syntax:

array_push($md_array['sub_array_key'], $new_element);

where:

• $md_array is the multidimensional array
• 'sub_array_key' is the key of the sub-array you want to add to
• $new_element is the new element you want to push

For example, to add a new element to the 'recipe_type' sub-array, you would use:

array_push($md_array['recipe_type'], $newdata);

Adding to Incrementing Index Sub-Arrays

If you want to add elements to the sub-array's incrementing index, you can simply access it through the array's key:

$md_array['sub_array_key'][] = $new_element;

For example, to add a new element to the 'cuisine' sub-array at the next available index:

$md_array['cuisine'][] = $newdata;
