Sorting Arrays

I do always have hard times with sorting especially with arrays. And this time I want to share what I got after those sorting times. hehehe. Enjoy! :D

 

static function sortAscending(&$arr, $key){ 
    $sort_col = array();  
    foreach ($arr as $sub) $sort_col[] = $sub[$key]; 
    if(is_numeric($sort_col[0])) 
        array_multisort($sort_col, SORT_NUMERIC, $arr); 
    else if(is_string($sort_col[0])){ 
        $sort_col = array_map(’strtolower’, $sort_col); 
        array_multisort($sort_col, SORT_STRING, $arr); 
    } 
} 
 
static function sortDescending(&$arr, $key){ 
    $sort_col = array(); 
    foreach ($arr as $sub) $sort_col[] = $sub[$key]; 
    if(is_numeric($sort_col[0])) 
        array_multisort($sort_col, SORT_NUMERIC, SORT_DESC, $arr); 
    else if(is_string($sort_col[0])){ 
        $sort_col = array_map(’strtolower’, $sort_col); 
        array_multisort($sort_col, SORT_STRING, SORT_DESC, $arr); 
    } 
}

For more codes, just leave a comment. :D
