I don't think to use any. I am using PHP on an apache-webserver, if
that makes a difference.
Could also not reproduce this on linux with Version 5.2.6, had no
higher versions on a linux system to test it. Will try that later.

I can't reproduce this on Linux or OS X
Do you have any Zend Extensions enabled such as eAccelerator, APC, Zend
Optimizer or anything like that?

Except from the "<?php" and "?>" I already posted the shorter script.
<?php
function test() {
$array = array("test");
foreach($array as $element) {
for($j=0;$j<5;$j++) {
continue 2;
}
//inserting code here affects return-value
return true;
}
return false;
}
echo test()?"true":"false";
?>

Description:
------------
The echo ""; affects the "return true;" below.
As long as the echo is there everything works as expected, if you put
"//" in front of the echo, the return will be called even if it should
not.
Reproduce code:
---------------
function matchHostList($host, $list_file) {
$host = explode(".", $host);
//$list_contents = explode("\n", file_get_contents($list_file));
$list_contents = array("www.google.de");
foreach($list_contents as $list_host) {
$list_host = explode(".", rtrim($list_host));
//if the list-host is more specific than the tested host we can't
match
if(count($host) < count($list_host))
continue;
for($i = 1;$i<=count($list_host) && $i <= count($host);$i++) {
if($list_host[count($list_host)-$i] != $host[count($host)-$i])
continue 2;
}
echo ""; //this is necessary to avoid wrong return
return true;
}
return false;
}
echo matchHostList("false.google.de", "")?"true":"false";
Expected result:
----------------
When running as shown above this returns false (because "continue 2;"
continues the loop above the "return true;"), this is OK.
If you remove the echo ""; above the "return true;" You would expect
that nothing changes (because we only removed some null-output), but in
fact the return value changes to true.
Actual result:
--------------
see Expected result
