试试这样吧
function sortFunction( $a,$b ) {
return strtotime($a[1]) - strtotime($b[1]);
}
usort($data,"sortFunction"); //Here You can use asort($data,"sortFunction")
或者你可以尝试细节(它的建议)
function sortFunction($a,$b)
if ($a[1] == $b[1]) return 0;
return strtotime($a[1]) - strtotime($b[1]);
}
usort($data,"sortFunction");
由于strtotime不服从d / m / Y格式尝试这样
$orderByDate = $my2 = array();
foreach($data as $key=>$row)
{
$my2 = explode('/',$row[1]);
$my_date2 = $my2[1].'/'.$my2[0].'/'.$my2[2];
$orderByDate[$key] = strtotime($my_date2);
}
array_multisort($orderByDate,SORT_DESC,$data);
