1.2.97. Can’t Call Generator

It is not possible to call directly a generator: a generator <https://www.php.net/`generator>`_ is a method that uses the yield or yield from keyword.

Such structure shall be used directly in a foreach() structure, or with the function iterator_to_array().

<?php

function foo() {
     echo __FUNCTION__;
     yield 1;
}

// Won't display anything, even 'foo'
foo();

// displays both foo and 1
foreach(foo() as $g) {
     print $g;
}

?>
