Below programs illustrate the strptime() function in PHP:

Program 1:

<?php

// Declaring the format of date/time
$format = "%d/%m/%Y %H:%M:%S";

// Parsing the date/time
$dt = strftime( $format );
echo "$dt";
print_r(strptime( $dt, $format ));
?>

Output:

22/08/2018 11:46:57Array
(
    [tm_sec] => 57
    [tm_min] => 46
    [tm_hour] => 11
    [tm_mday] => 22
    [tm_mon] => 7
    [tm_year] => 118
    [tm_wday] => 3
    [tm_yday] => 233
    [unparsed] => 
)

Program 2:

<?php

// Ddeclaring a different format of date/time
$format="%d/%m/%y %I:%M:%S";

// Parsing the date/time
$dt = strftime( $format );
echo "$dt";
print_r(strptime( $dt, $format ));
?>

Output:

22/08/18 11:46:59Array
(
    [tm_sec] => 59
    [tm_min] => 46
    [tm_hour] => 11
    [tm_mday] => 22
    [tm_mon] => 7
    [tm_year] => 118
    [tm_wday] => 3
    [tm_yday] => 233
    [unparsed] => 
)
