How can I Transform Multidimensional Column Data into Row Data Using array_column in PHP?

Restructuring Multidimensional Column Data into Row Data Using array_column

Some programming tasks, such as exchanging columns for rows in a multidimensional array, can be simplified with the right tools. In this case, the array_column function offers a straightforward solution.

To transform an associative array of column data into a multidimensional array of row data, follow these steps:

1. Create an empty array to store the results.
2. Iterate through the keys of the original array.
3. For each key, use the array_column function to extract the corresponding column values.
4. Add the extracted values as a new row to the results array.

Here's the code to achieve this transformation:

<code class="php">$result = array();

foreach($where['id'] as $k => $v) {
  $result[] = array_column($where, $k);
}</code>

The resulting array will now be structured as:

<code class="php">array(
    array(12, '1999-06-12'),
    array(13, '2000-03-21'),
    array(14, '2006-09-31')
);</code>

which matches the desired output.

This method leverages the power of array_column, a built-in PHP function designed for such array manipulations. By combining iteration and column extraction, we can seamlessly transform the data into the desired format with ease.
