Convert this string to timestamp PHP [duplicate]

Answer 1

In your code strtotime() is attempting to convert 13/10 as the tenth day of the 13th month, which returns an error.

If you want to parse a date string with a custom format, it's better to use DateTime::createFromFormat() instead:

$dtime = DateTime::createFromFormat("d/m G:i", "13/10 15:00");
$timestamp = $dtime->getTimestamp();

Answer 2

  $timestamp = strtotime("13-10-2013 15:00");

This can be important:

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.

To avoid potential ambiguity, it's best to use ISO 8601 (YYYY-MM-DD) dates or DateTime::createFromFormat() when possible.
