Answer 1

What you are looking for is parallel which is a succinct concurrency API for PHP 7.2+

$runtime = new \parallel\Runtime();

$future = $runtime->run(function() {
    for ($i = 0; $i < 500; $i++) {
        echo "*";
    }

    return "easy";
});

for ($i = 0; $i < 500; $i++) {
    echo ".";
}

printf("\nUsing \\parallel\\Runtime is %s\n", $future->value());

Output:

.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*..*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*
Using \parallel\Runtime is easy
