What are the performance implications of creating arrays in PHP includes with variable names?

Creating arrays in PHP includes with variable names can lead to performance issues because each time the include is called, the array will be re-created in memory. To solve this, it is recommended to define the array outside of the include and pass it as a parameter to the included file. 

// Define the array outside of the include
$array = ['item1', 'item2', 'item3'];

// Include the file and pass the array as a parameter
include 'file.php';
