1.2.95. 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
oryield 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;
}
?>
