How can unset() function be used to release memory in PHP scripts with large data sets?

When working with large data sets in PHP scripts, memory management is crucial to prevent memory leaks and optimize performance. The unset() function can be used to release memory by removing variables or elements from arrays that are no longer needed. By unsetting variables or elements after they are no longer needed, you can free up memory and improve the efficiency of your PHP scripts.

// Example of using unset() to release memory in PHP scripts with large data sets
$largeDataSet = range(1, 1000000); // Creating a large data set

// Process the data set

// Unset the variable to release memory
unset($largeDataSet);
