按日期按日期在php中按日期排序数组

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);
