What are the best practices for managing memory usage in PHP to optimize performance?

To manage memory usage in PHP and optimize performance, it is important to avoid unnecessary memory allocations, limit the size of data structures, and release memory when it is no longer needed. Additionally, using efficient algorithms and data structures can help reduce memory usage. 

// Example code snippet to manage memory usage by limiting the size of data structures

// Define a maximum limit for the number of elements in an array
$max_limit = 1000;

// Initialize an empty array
$data = [];

// Add elements to the array, ensuring it does not exceed the maximum limit
for ($i = 0; $i < $max_limit; $i++) {
    $data[] = $i;
}

// Release memory by unsetting the array
unset($data);
