PHP: Adding Elements to Multidimensional Arrays with array_push
When working with multidimensional arrays, adding elements can be tricky, especially when using array_push. Let's clear up the confusion.
Scenario:
You have a multidimensional array $md_array with sub-arrays recipe_type and cuisine, and you want to add new elements to these sub-arrays using array_push. The new elements are stored in a temporary array $newdata.
Solution:
Adding elements to multidimensional arrays using array_push requires specifying the sub-array keys. Here's the syntax:
<code class="php">$md_array["sub_array_key"][] = $newdata;</code>
Example 1: Adding to recipe_type
To add $newdata to the recipe_type sub-array, use:
<code class="php">$md_array["recipe_type"][] = $newdata;</code>
This will append $newdata as the next element in the recipe_type sub-array, with an incremented index.
Example 2: Adding to cuisine
Similarly, to add $newdata to the cuisine sub-array, use:
<code class="php">$md_array["cuisine"][] = $newdata;</code>
This will append $newdata as the next element in the cuisine sub-array, again with an incremented index.
Note:
Array push is typically used with sequentially indexed arrays ($arr[0], $arr[1], etc.). However, since your sub-arrays have sequential indexes, you can still utilize array_push to append new elements in an ordered manner.
