Are there best practices for using PHP to prioritize and manage cron jobs based on server load and resource availability?

When managing cron jobs in PHP, it is important to prioritize tasks based on server load and resource availability to ensure optimal performance. One way to achieve this is by implementing a system that monitors server metrics such as CPU usage, memory usage, and disk space, and adjusts the scheduling of cron jobs accordingly. 

// Sample PHP code to prioritize and manage cron jobs based on server load and resource availability

// Function to check server load and resource availability
function checkServerMetrics() {
    // Implement logic to check CPU usage, memory usage, disk space, etc.
    // Return a score based on server load and resource availability
}

// Get the score for the current server metrics
$serverScore = checkServerMetrics();

// Define cron jobs with their respective priorities
$cronJobs = [
    ['job' => 'task1', 'priority' => 1],
    ['job' => 'task2', 'priority' => 2],
    ['job' => 'task3', 'priority' => 3],
];

// Sort cron jobs based on priority
usort($cronJobs, function($a, $b) {
    return $a['priority'] <=> $b['priority'];
});

// Loop through sorted cron jobs and execute based on server score
foreach ($cronJobs as $job) {
    if ($serverScore >= $job['priority']) {
        // Execute the cron job
        // Implement logic to run the task
        echo "Running cron job: " . $job['job'] . "\n";
    } else {
        // Log or handle the case where the server score is lower than job priority
        echo "Skipping cron job: " . $job['job'] . "\n";
    }
}
