(PHP 5 >= 5.5.0, PHP 7)

Generator::send — Send a value to the generator

Description

public Generator::send ( mixed $value ) : mixed

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 Generator::next() call (like it is done in Python).

Examples

Example #1 Using Generator::send() 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!');
?>

The above example will output:

I'm printer!
Hello world!
Bye world!
