在php中将dd-mm-yyyy转换为yyyy-mm-dd

Question

I tried the following code to change the dateformat from dmy to ymd, but when using i got wrong dates.

My code

$sdate11=date("Y-m-d", strtotime($_POST["txtstartdates"]) );
$sdate111=date("Y-m-d", strtotime($_POST["txtenddates"]) );

dates inserted were

30-05-2013 and  31-05-2013

the date it returned was

2035-11-03 and 2036-11-02 

could you please help me to find what was the problem here and solve it

Thank you.

Answer 1

Try with split like

$a = split('-',$_POST["txtstartdates"]);

or you can use explode even like

$a = explode('-',$_POST["txtstartdates"]);
$my_new_date = $a[2].'-'.$a[1].'-'.$a[0];

Here strtotime will not work for the format dd-mm-yyyy
