如何在codeigniter中用其他东西填充url空格？

Question

I am trying to create a url for search results with input values included in url. Everything is working fine except "blank spaces".

I am getting this at the moment:

localhost/admin/search-results/san diego-01/25/2016-01/27/2016-guest House-7

PS, 'San Diego' & 'Guest House'. I can manually change the value of drop downs by adding '-' in value but I afraid doing so will not query DB. Same goes for location text input.

Controller:

public function custom_search() {
    $seg1 = $this->input->post('search[1]');
    $seg2 = $this->input->post('search[2]');
    $seg3 = $this->input->post('search[3]');
    $seg4 = $this->input->post('search[4]');
    $seg5 = $this->input->post('search[5]');

    $segment_array = $this->input->post('search');
    $segments = implode("-", $segment_array);
    redirect('search-results/'.$segments);
}

Try use urlencode function.

This function is convenient when encoding a string to be used in a query part of a URL, as a convenient way to pass variables to the next page.

public function custom_search() {
    $seg1 = $this->input->post('search[1]');
    $seg2 = $this->input->post('search[2]');
    $seg3 = $this->input->post('search[3]');
    $seg4 = $this->input->post('search[4]');
    $seg5 = $this->input->post('search[5]');

    $segment_array = $this->input->post('search');
    $segments = implode("-", $segment_array);
    redirect('search-results/'.urlencode($segments));
}
