strtotime

Definition and usage

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

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

Note: Note the dates in m/d/y or dmy format, and if the delimiter is a slash (/), the m/d/y format of America is used. If the separator is a horizontal bar (-) or a dot (.), then the European dmy format is used. To avoid potential errors, you should use the YYYY-MM-DD format whenever possible or use date_create_from_format() function.

Example

Parses the English text date and time to a Unix timestamp:

 <?php
echo ( strtotime ( "now" ) . "<br>" ) ;
echo ( strtotime ( "15 October 1980" ) . "<br>" ) ;
echo ( strtotime ( "+5 hours" ) . "<br>" ) ;
echo ( strtotime ( "+1 week" ) . "<br>" ) ;
echo ( strtotime ( "+1 week 3 days 7 hours 5 seconds" ) . "<br>" ) ;
echo ( strtotime ( "next Monday" ) . "<br>" ) ;
echo ( strtotime ( "last Sunday" ) ) ;
?>
