Getting duplicate key values in array
- by WmasterJ
For some reason when trying to populate an array I am not getting the desired result. In the first part I create an array of arrays, the key of each has a name such as "Biology Education". But when I then populate that same array it doesn't for some reason use the same array element but a new one.
So part 1 results in an array with 13 array elements (empty). After part 2 has run the array has 26 array elements, with the first 13 empty and the other 13 populated as wanted.
The reason why I want to work is that the first 13 array elements are sorted. The last 13 are jumbled.
Why is this happening and how can I correct it?
// PART 1
// Create array of research areas
$research_result = db_fetch_array($research['research_query_result']);
$research['areas'] = explode("\n", $research_result['options']);
// Put the values as key and every key the new value of an array object
$research['areas'] = array_fill_keys($research['areas'], array());
// PART 2
foreach($research['user'] as $uid => &$user_object) {
$user_object->profile_research_areas = explode(", ", $user_object->profile_research_areas);
foreach($user_object->profile_research_areas as $key => $area) {
$research['areas'][$area][] = $uid;
}
}
