PHP Strtotime -1Month -2Month

Strtotime() doesn't work with dd/mm/YYYY format

Here is the simplified solution:

$date = '25/05/2010';
$date = str_replace('/', '-', $date);
echo date('Y-m-d', strtotime($date));

Result:

2010-05-25

The strtotime documentation reads:

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

PHP strtotime() function that accepts a format?

If you have PHP 5.3:

$date = DateTime::createFromFormat('d/m/Y H:i:s', '03/05/2011 16:33:00');
echo $date->getTimestamp();

get strtotime of specific time in php

If you're trying to get a timestamp of today at 8pm, it's actually much more simple than using date since you can use relative times in a strtotime:

$curtime = strtotime('today 8pm');

If you test this with date:

echo date('Y-m-d H:i:s', $curtime); // Returns 2014-12-17 20:00:00

Here's a whole writeup on relative date formats that explains how you can construct proper relative dates.

strtotime() DateTime class analog method

That would be DateTime::__construct:

$date = new DateTime('Sunday');

PHP strtotime(): date showing '1970-01-01 ' after conversion

Your format is not a format that the parser understands.

In your case 13 is not a "month". So the parser doesn't understand to date.

You should use DateTime::createFromFormat():

$date = DateTime::createFromFormat('m-d-Y H:i:s','04-13-2018 0:00:53');
echo $date->format('Y-m-d H:i:s');

Output:

2018-04-13 00:00:53

Note that the format could also be: 'm-d-Y G:i:s' with G for "24-hour format of an hour without leading zeros".

strtotime With Different Languages?

From the docs

Parse about any English textual datetime description into a Unix
timestamp

Edit: Six years down the road now, and what was meant to be a side-note about why strtotime() was an inappropriate solution for the issue at hand became the accepted answer /p>

To better answer the actual question I want to echo Marc B's answer: despite the downvotes, date_create_from_format, paired with a custom Month interpreter will provide the most reliable solution

However it appears that there is still no silver-bullet for international date parsing built-in to PHP for the time being.

How to exactly use PHP strtotime with 'this monday' combined with a time?

Try this:

$next_valid_date_time = strtotime('this Monday 20:00');

if(time() > $next_valid_date_time) {
    $next_valid_date_time = strtotime('Monday next week 20:00');
} 

echo date('Y-m-d H:i', $next_valid_date_time);

PHP strtotime EST back and forth conversion

I'd say that this is because currently New York is on daylight savings time - EDT rather than EST. This affects things like so:

date_default_timezone_set("America/New_York");
strtotime("10/31/2012 7:30pm"); // translates to "Wed, 31 Oct 2012 19:30:00 -0400"
strtotime("10/31/2012 7:30pm EDT"); // translates to "Wed, 31 Oct 2012 19:30:00 -0400"
strtotime("10/31/2012 7:30pm EST"); // translates to "Wed, 31 Oct 2012 20:30:00 -0400"

The quick fix is probably to not add the timezone to the string, strtotime() will use the correct default timezone you set.

You can be a bit more exact about how your date is being parsed by using the DateTime createFromFormat function:

$date = DateTime::createFromFormat('m/d/Y g:ia', "10/31/2012 7:30pm");
echo $date->format('U');

Alternatively if you wait until November the problem will resolve itself :-)
