Answer 1

Use this code :

$originalDate = "12/May/2018";
$originalDate =str_replace("/", " ", $originalDate);
$newDate = date("Y-m-d", strtotime($originalDate));
echo $newDate;

Answer 2

There's no need for any manual parsing.
You should use PHP's DateTime class, which is much more flexible than the old date() -function.

Here's an example that does what you want:

$date = DateTime::createFromFormat('d/M/Y', '12/May/2018');
echo $date->format('Y-m-d');

Answer 3

That date format is not supported by strtotime.
But replacing the / with space is a supported format.

$originalDate = "12/May/2018";
$newDate = date("Y-m-d", strtotime(str_replace("/", " " ,$originalDate)));
echo $newDate;

The reason you get 1969-12-31 is because UNIX 0 is 1970-01-01 00:00:00.
When strtotime can't parse the date it returns false .
False can be typeconverted to 0 .
That means date reads it as "Ymd" at UNIX time 0 (1970), and because of your timezone you get 1969-12-31.

Answer 4

try this,

$originalDate = "12/May/2018";
$newDate = date_format(date_create_from_format("j/F/Y", $originalDate), 'Y-m-d');
echo $newDate; 

Note : if your day format is 01 use d , if 1 use j

The output is: 2018-05-12
