1. You need to be more coherent when asking a question.
2. You should actually ask a question.
3. Before asking, attempt a solution.

you could use regular expressions to create an associative array.

$cloud = array();
preg_match_all('/.*?process.*/', $string_containing_all_possible_forms, $matches);
foreach($matches as $match)
{
  $cloud['process'][] = $match;
}
