Example #1 ReflectionGenerator::getTrace() example
<?php
function foo() {
yield 1;
}
function bar()
{
yield from foo();
}
function baz()
{
yield from bar();
}
$gen = baz();
$gen->valid(); // start the generator
var_dump((new ReflectionGenerator($gen))->getTrace());The above example will output something similar to:
array(2) { [0]=> array(4) { ["file"]=> string(18) "example.php" ["line"]=> int(8) ["function"]=> string(3) "foo" ["args"]=> array(0) { } } [1]=> array(4) { ["file"]=> string(18) "example.php" ["line"]=> int(12) ["function"]=> string(3) "bar" ["args"]=> array(0) { } } }
