In PHP, how do I deep copy arrays in a high-traffic application?

In high-traffic applications, it’s important to efficiently manage memory and ensure that copying arrays doesn't lead to unintended side effects. Deep copying arrays in PHP can be achieved using various methods. Below is an example demonstrating how to perform a deep copy of an array safely.

"John", "skills" => ["PHP", "JavaScript"], "projects" => [ ["title" => "Project A", "status" => "completed"], ["title" => "Project B", "status" => "ongoing"] ] ]; // Deep copy of the original array $copiedArray = deepCopyArray($originalArray); // Modifying the copied array $copiedArray["projects"][0]["status"] = "failed"; // Output the arrays var_dump($originalArray); var_dump($copiedArray); ?>
