Generator::send

Generator::send

Send a value to the generator

mixed **Generator::send** mixed $value

Sends the given value to the generator as the result of the current yield expression and resumes execution of the generator.

If the generator is not at a yield expression when this method is called, it will first be let to advance to the first yield expression before sending the value. As such it is not necessary to "prime" PHP generators with a call (like it is done in Python). Generator::next

valueValue to send into the generator. This value will be the return value of the yield expression the generator is currently at.

Returns the yielded value.

Voorbeeld: Using to inject values

<?php
function printer() {
    echo "I'm printer!".PHP_EOL;
    while (true) {
        $string = yield;
        echo $string.PHP_EOL;
    }
}

$printer = printer();
$printer->send('Hello world!');
$printer->send('Bye world!');
?>

I'm printer!
Hello world!
Bye world!
