Related introduction:

The strtotime() function parses any English text date or time description into a Unix timestamp (number of seconds since January 1 1970 00:00:00 GMT).

Note: If the year representation uses a two-digit format, values ​​0-69 will be mapped to 2000-2069, and values ​​70-100 will be mapped to 1970-2000.

Note: Please note that for dates in m/d/y or d-m-y format, if the separator is a slash (/), the American m/d/y format is used. If the delimiter is a dash (-) or a dot (.), the European d-m-y format is used. To avoid potential errors, you should use YYYY-MM-DD format whenever possible or use the date_create_from_format() function.

Syntax

strtotime(time,now);

Parameters

time Required. Specifies a date/time string.​

now Optional. Specifies the timestamp used to calculate the return value. If this parameter is omitted, the current time is used.
