(PHP 7)
ReflectionGenerator::getExecutingGenerator — Gets the executing Generator object
Get the executing Generator object
此函数没有参数。
Returns the currently executing Generator object.
Example #1 ReflectionGenerator::getExecutingGenerator() example
<?php
class GenExample
{
public function gen()
{
yield 1;
}
}
$gen = (new GenExample)->gen();
$reflectionGen = new ReflectionGenerator($gen);
$gen2 = $reflectionGen->getExecutingGenerator();
var_dump($gen2 === $gen);
var_dump($gen2->current());
以上例程的输出类似于：
bool(true) int(1);
