the problem is you didnt read the third note in the PHP Manual for strtotime explaining what the problem is — Gordon

DD/MM/YYYY Is not a valid date format (The manual outlines it must follow one of the supported date and time formats.) So, instead, it should be MM/DD/YYYY:

echo strtotime("05/31/2011");

Or, I guess as others have posted, the european (ISO8601 Notations) version uses hyphens:

echo strtotime("31-05-2011");

Use dashes instead of forward slashes.

echo strtotime("31-05-2011"); // outputs 1306821600

For European formatted dates (DD-MM-YYYY) use dashes not slashes:

echo strtotime('31-05-2011');

How about using php's DateTime functions?

DateTime::createFromFormat('d/m/Y', '31/05/2011');
