What best practices can be recommended for optimizing PHP code performance when dealing with a high volume of function calls and data processing tasks?

When dealing with a high volume of function calls and data processing tasks in PHP, it is important to optimize the code for performance. One way to do this is by minimizing the number of function calls and reducing the amount of data processing required. This can be achieved by using efficient algorithms, avoiding unnecessary loops, and optimizing database queries. 

// Example of optimizing PHP code performance by reducing function calls and data processing

// Bad practice - multiple function calls and data processing within loops
foreach ($data as $item) {
    $processedData = processData($item);
    $result = performTask($processedData);
}

// Good practice - minimize function calls and data processing outside of loops
foreach ($data as $item) {
    $result = performTask($item);
}

// Function to perform task
function performTask($data) {
    // Task implementation
    return $result;
}
