php - [ solver } Sort gallery By date -


i have problem, created gallery works function sort images depends on day ignores mouths , minutes ... form used sort ::::: | d/m/y h:i:s |, when move mouth lose order because depends on day said want take in consideration mouth too. 

 $date = date ("d/m/y h:i:s",filemtime($dir_mini));  function sortfunctionasc ( $a , $b ) { return strcmp($a["date"], $b["date"]); }

and here give part sort gallery 

//boucle sur le répertoire on extrait aussi le nom de l'image et de la miniature      $images = array();     while ( false !== ($fichier = readdir($ouverture)))      {                    $berk = array('.', '..');              $dir_mini = $dos_mini.$fichier;             $dir_img  = $dos_img.$fichier;             $img_name = $dir_mini ;              $img_name = preg_replace('#jpg|png|jpg|mini|/|\.#i', '',$img_name);             $date_precise = date ("d/f/y-h:i",filemtime($dir_mini));             $date = date ("d/m/y h:i:s",filemtime($dir_mini));               if(!in_array($fichier, $berk) , !is_dir($dir_mini) , !is_dir($dir_img) )              {                 $image = array();                 $image['date_precise']  = $date_precise;                 $image['date']  = $date;                 $image['img']   = $dir_img;                 $image['thumb'] = $dir_mini;                 $images[] = $image;              }        }        closedir($ouverture);     // cette deux fonctions trient les images en fonction de date  asc croissant, desc décroissant  function sortfunctionasc ( $a , $b ) { return strcmp($a["date"], $b["date"]); } function sortfunctiondesc( $b , $a ) { return strcmp($a["date"], $b["date"]); }  if (isset ($_get['asc']))  { usort ($images,"sortfunctionasc"); } if (isset ($_get['desc'])) { usort ($images,"sortfunctiondesc"); } if (!isset($_get['asc']) , !isset($_get['desc'])) { usort ($images,"sortfunctiondesc") ;}

i think should convert date timestamp sorting. simple use filemtime ( string $filename ) without date ("d/m/y h:i:s"... stuff

function sortfunctionasc ( $a , $b ) { return $a["stamp"] < $b["stamp"]); } function sortfunctiondesc( $b , $a ) { return $a["stamp"] < $b["stamp"]); }

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
