How to Transform a 2D Array into a String with Transposition, Merging, and Concatenation?

Transpose a 2D Array, Merge Elements within Rows, and Concatenate Rows

You have a two-dimensional array and need to transform it into a string that follows a specific format. Let's delve into the steps involved:

Transposing the Array

To switch the rows of the array into columns, we use a nested loop that iterates through each element in the array:

<code class="php">$transposedArray = [];
for ($j = 0; $j <p><strong>Merging Elements within Rows</strong></p>
<p>Next, we need to combine the elements within each row into a single string, separated by commas:</p>
<pre class="brush:php;toolbar:false"><code class="php">$mergedRows = [];
foreach ($transposedArray as $row) {
    $mergedRows[] = implode(',', $row);
}</code>

Concatenating Rows

Finally, we concatenate the merged rows into a single string, separating them with pipes:

<code class="php">$result = implode('|', $mergedRows);</code>

Putting it all together, you can use this code to perform the transformations:

<code class="php">$transposedArray = [];
for ($j = 0; $j <p>This will produce the desired string in the format you specified.</p></code>
