pht\Thread::join — Joins a thread
This method will join the spawned thread (though it will first wait for that thread's internal task queue to finish). As a matter of good practice, threads should always be joined. Not joining a thread may lead to undefined behaviour.
This function has no parameters.
No return value.
Example #1 Joining a thread
<?php
use pht\Thread;
$thread = new Thread();
$thread->start();
$thread->join();
