php array flip value as key and make it simple -

i have been troubling format array correctly have code:

    require('simple_html_dom.php');      $table = array();     $html = file_get_html('apc.html');     foreach($html->find('tr') $row) {          $rack = ltrim($row->find('td',0)->plaintext);         $location = ltrim($row->find('td',1)->plaintext);         $usage = ltrim($row->find('td',2)->plaintext);         $auk = ltrim($row->find('td',3)->plaintext);         $cost = ltrim($row->find('td',4)->plaintext);        $rack = rtrim($rack);      $location = rtrim($location);       $usage = rtrim($usage);      $auk = rtrim($auk);      $cost = rtrim($cost);          $table[$rack][$usage][$auk][$cost] = true;      } echo '<pre>'; print_r($table); echo '</pre>'; 

using simple_html_dom above can convert html table array follow:

[rack01] => array         (             [741,60] => array                 (                     [1.409,04] => array                         (                             [267,72] => 1                         )                  )              [110,88] => array                 (                     [210,67] => array                         (                             [40,03] => 1                         )                  )          )      [rack 09] => array         (             [843,84] => array                 (                     [1.603,30] => array                         (                             [304,63] => 1                         )                  )          ) 

i have result below:

array(  [0]  => array (      [usage] => 'rack 01',      [usage] => '741,60',      [auk] => '1.409.04',      [cost] => '267,72')  [1]  => array (      [usage] => 'rack 02',      [usage] => 'value???',      [auk] => 'value???',      [cost] => 'value???') 

any apreaciate

something this. note trim both left , right:

foreach($html->find('tr') $row) {     $rack     = trim($row->find('td',0)->plaintext);     $location = trim($row->find('td',1)->plaintext);     $usage    = trim($row->find('td',2)->plaintext);     $auk      = trim($row->find('td',3)->plaintext);     $cost     = trim($row->find('td',4)->plaintext);      $table[] = array('rack'  => $rack,                      'usage' => $usage,                      'auk'   => $auk,                      'cost'  => $cost); }
