SimpleXML infinite loop when a cast is used inside a foreach #12208
Description
Description
The following code:
<?php
$xml = "<root><a>1</a><a>2</a></root>";
$xml = simplexml_load_string($xml);
$a = $xml->a;
foreach ($a as $test) {
var_dump((string) $a->current());
var_dump((string) $a);
}Resulted in this output:
an infinite loop
But I expected this output instead:
string(1) "1"
string(1) "1"
string(1) "2"
string(1) "1"
I think at least, because $a always refers to the first element implicitly, and only current points to the current iterated-over item?
This is basically the same as #12192, but triggered in a different yet similar way.
