Bug description: no array being returned from function
Description:
------------
It seems that I am not being able to return an array from a function. I
read a serialized string, unserialize it and then call a recursive
function to get the deepest keys and values
Reproduce code:
---------------
$test_serial = <<< FO
a:5:{i:0;a:7:{s:8:"question";s:31:"What is your tv watching
habits";s:5:"field";s:10:"checkboxes";s:7:"default";N;s:9:"charwidth";N;s:5:"lines";N;s:6:"maxlen";N;s:7:"options";s:54:"never
watch tv |always am on the tube |i dont own a
tv";}i:1;a:7:{s:8:"question";s:27:"What is your favorite
genre";s:5:"field";s:12:"radiobuttons";s:7:"default";N;s:9:"charwidth";N;s:5:"lines";N;s:6:"maxlen";N;s:7:"options";s:19:"horror
|sex
|comedy";}i:2;a:7:{s:8:"question";s:0:"";s:5:"field";s:9:"textfield";s:7:"default";s:6:"sfasdf";s:9:"charwidth";s:8:"sadfasdf";s:5:"lines";N;s:6:"maxlen";s:7:"asdfasd";s:7:"options";N;}i:3;a:7:{s:8:"question";s:27:"what
is your favorite
color";s:5:"field";s:9:"textfield";s:7:"default";s:0:"";s:9:"charwidth";s:0:"";s:5:"lines";N;s:6:"maxlen";s:0:"";s:7:"options";N;}i:4;a:7:{s:8:"question";s:14:"favorte
things";s:5:"field";s:9:"textfield";s:7:"default";s:0:"";s:9:"charwidth";s:0:"";s:5:"lines";N;s:6:"maxlen";s:0:"";s:7:"options";N;}}
FO;
$test = unserialize($test_serial);
$test_keys = array();
$test_val = array();
function getarr_items($array,$mode){
$newarray = array();
if(is_array($array)){
foreach($array as $key => $val){
if(is_array($val)){
getarr_items($val,$mode);
}
else {
if($mode == "k"){
$newarray[] = $key;
}
else $newarray[] = $val;
}
}
}
return $newarray;
}
$test_keys = getarr_items($test,'k');
$test_val = getarr_items($test,'v');
print_r($test_keys);
echo "<------>";
print_r($test_val);
Expected result:
----------------
should return an array with values
Actual result:
--------------
empty array
