PHP日期/时间到时间戳（自定义格式）

Question

Any one got a function to like strtotime() but the takes the format as input?

For example I need to convert yyyymmdd to a timestamp, or perhaps yyyyddmm . So I would like to specify the format used. Also Im on Windows so strptime() isn't an option.

Answer 1

PHP 5's DateTime class has the createFromFormat method which does what you need.

However, it requires PHP 5.3 so it's not always an option (yet).

Answer 2

Very easy to write a function, just take a look at mktime ...

// Assumes yyyy-mm-dd
function fromdate($date) {
    $d = explode("-", $date);
    return mktime(0, 0, 0, $d[1], $d[2], $d[0]);
}
