explode 2013-11-17 13:51:03 ออกยังไงมันมี - กับ :

$getA = "2013-11-17 13:51:03";
 $v = array();
 
list($a,$b) = explode(" ",$getA);
$v[] = explode("-",$a);
$v[] = explode(":",$b);

foreach ($v as $v1) {
    foreach ($v1 as $v2) {
        echo "$v2<br>";
    }
}

echo str_replace(array(" ",":","-"), PHP_EOL,  "2013-11-17 13:51:03");

print_r(explode("\n",str_replace(array(" ",":","-"), PHP_EOL,  "2013-11-17 13:51:03")));

Array
(
    [0] => 2013
    [1] => 11
    [2] => 17
    [3] => 13
    [4] => 51
    [5] => 03
)

$getA = new DateTime('2013-11-17 13:51:03');

$year = $getA->format('Y');
$month = $getA->format('m');
$day = $getA->format('d');
$hour = $getA->format('H');
$minute = $getA->format('i');
$second = $getA->format('s');
