PHP Bug Type: Unknown/Other Function
Bug description: a recursive function doesn't return an expected string
Description:
------------
The recursive function looks in an array for a certain text. When it finds
it, it returns the text. The problem is that it never returns it (but if I
put a print statement instead of a return, it will print it).
Reproduce code:
---------------
$arr = array('0'=>array('0'=>'zero-zero','1'=>'zero-un'),
'1'=>array('0'=>'un-zero','1'=>'un-un'));
print search_array('zero-un', $arr);
function search_array ($page, $item) {
if (is_array($item)) {
foreach ($item as $k => $v) {
if (is_array($v)) {
search_array($page, $v);
}
elseif ($v == $page) {
return $v;
}
}
} else {
return "Not an array!";
}
}
Expected result:
----------------
zero-un
Actual result:
--------------
Nothing!
