What are some best practices for handling script execution times and server timeouts in PHP development, especially in the context of batch processing and image manipulation tasks?

Handling script execution times and server timeouts in PHP development involves setting appropriate time limits for script execution and handling potential timeouts gracefully. For batch processing and image manipulation tasks, it is important to monitor the progress of the task and adjust the time limits accordingly. 

// Set maximum execution time
set_time_limit(0); // 0 means no time limit

// Handle potential timeouts gracefully
ignore_user_abort(true); // continue script execution even if client disconnects

// Example of batch processing task
$items = [...]; // array of items to process
foreach ($items as $item) {
    // Process each item
    // Check execution time and adjust as needed
    if (time() - $_SERVER['REQUEST_TIME_FLOAT'] > 30) { // adjust 30 seconds as needed
        // If time limit exceeded, save progress and exit
        saveProgress($item);
        exit;
    }
}

// Function to save progress
function saveProgress($item) {
    // Save progress to database or file
}
