How to Use array_push() for Multidimensional Arrays in PHP?

Adding Elements to Multidimensional Arrays with PHP's array_push

Working with multidimensional arrays can be puzzling, especially when attempting to add new elements. This issue arose when the task was to append data from a loop, stored in $newdata, to the sub-arrays 'recipe_type' and 'cuisine' within the given $md_array.

To achieve this, you can utilize the array_push function, but with a slight adaptation to accommodate multidimensional arrays. The syntax goes as follows:

<code class="php">// To add data to 'recipe_type', use:
$md_array["recipe_type"][] = $newdata;

// To add data to 'cuisine', use:
$md_array["cuisine"][] = $newdata;</code>

By using the [] operator on the sub-array names within $md_array, you are essentially appending $newdata to the end of that sub-array. Each call to array_push() adds a new element to the specific sub-array in sequence.

While array_push is commonly used for sequential arrays, it remains applicable in this case due to the fact that your sub-arrays themselves use sequential indices, like ['0'], ['1'], and so on. Therefore, array_push can be employed to add elements to these sub-arrays with ease.
