How can PHP be used to determine the server load and manage resource allocation for different tasks?

To determine the server load and manage resource allocation for different tasks in PHP, you can use server monitoring tools like sys_getloadavg() to get the server load average. Based on the load average, you can then implement logic to allocate resources accordingly to different tasks or processes.

$load = sys_getloadavg();
$cpu_load = $load[0];

if($cpu_load < 0.7) {
    // Allocate more resources to high priority tasks
} elseif($cpu_load >= 0.7 && $cpu_load < 1.0) {
    // Allocate resources evenly to all tasks
} else {
    // Limit resources for non-essential tasks
}
