Question

I really like the strtotime() function, but the user manual doesn’t give a complete description of the supported date formats. strtotime('dd/mm/YYYY') doesn’t work, it works only with mm/dd/YYYY format.

If I have date in dd/mm/YYYY format, how can I convert it to YYYY-mm-dd?
I can do it by using explode() function, but I think there are better solutions.

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.
