如何让date（）在php中返回00:00

Question

i'm using date() function after fetching data from database i'm feeding it into date() function.

it works for every other input but fails for 0000-00-00 00:00:00 in this case it returns 01:01(but i want 00:00)

here is my code :

<?php
$timestamp = "0000-00-00 00:00:00";
echo date('d:m', strtotime(str_replace('-','/', $timestamp)));

i want to display it inside <title> tag something like this

title="<?php echo @date('d:m', strtotime(str_replace('-','/', $timestamp))); ?>" 

QUESTION:It is returning 01:01 for 0000-00-00 00:00:00 for others working fine how to make it to return 00:00(for 0000-00-00 00:00:00) ?

please help me thanks in advance

Answer 1

Your input date is invalid date so date function will not return wanted result. But this will work:

<?php
$timestamp = "0000-00-00 00:00:00";
$arr = explode(" ", $timestamp);
$arr = explode("-", $arr[0]);
echo $arr[1].':'.$arr[2];

or single line:

echo preg_replace('/(0000)-(00)-(00) (.+)/', '$2:$3', $timestamp);

or this one (it will work even with valid dates):

echo preg_replace('/([0-9]{4})-([0-9]{2})-([0-9]{2}) (.+)/', '$2:$3', $timestamp);
