explode and in_Array search not working

Question

OK here is the code codepad here http://codepad.org/ZQz0Kn3R

function processContent($content, $min_count = 2, $exclude_list = array()) {
    $wordsTmp = ex         


        

Answer 1

The problem is because $filter_array has spaces in it. Either:

$filter_array = array_map(function($el) { return trim($el); }, $filter_array);

Or

foreach ($filter_array as &$element) {
    $element = trim($element);
}
