Run PHP Task Asynchronously

To run a PHP task asynchronously, you can use the pcntl_fork() function to create a new process that runs the task in parallel with the main script. This allows the main script to continue executing without waiting for the task to complete.

// Start the task as a new process
$pid = pcntl_fork();

if ($pid == -1) {
  // Error: Unable to fork
} elseif ($pid) {
  // Parent process
  // Do other tasks here while the task runs in the background
} else {
  // Child process
  // Run the task here
  // exit() when the task is complete

Note: This is not recommended for long running task. For that you can use "php-resque" library which is a PHP port of resque library of ruby.
