Are there any potential performance drawbacks to using an array in PHP instead of a scalar for split parts?

Using an array in PHP instead of a scalar for split parts can potentially lead to performance drawbacks due to the increased memory usage and processing time required to handle arrays. To mitigate this issue, you can use a scalar variable to store split parts when possible to optimize performance.

// Example of using a scalar variable instead of an array for split parts
$string = "Hello World";
list($firstPart, $secondPart) = explode(" ", $string);

echo $firstPart; // Output: Hello
echo $secondPart; // Output: World
