PHP gmdate () function

Definition and Usage

The Gmdate () function formats the GMT/UTC date/time.

Similar to the date () function, the difference is that the time returned is Greenwich Mean Time (GMT).

Grammar

Hints and notes

Note: Before PHP 5.1.0, negative timestamps (dates before 1970) do not work under some systems (for example, Windows).

ExampleExample 1

When the following program is run in China (GMT +0800), the first line shows "Jan 01 2000 00:00:00" and the second line shows "Dec 31 1999 16:00:00".

<?phpecho date ("M D y h:i:s", Mktime (0,0,0,1,1,2000)), Echo gmdate ("M D y h:i:s", Mktime (0,0,0,1,1,2000));? >

Output:

Jan 00:00:00dec 31 1999 16:00:00

Example 2

<?phpecho ("Result with date (): <br/>"); Echo (Date ("L"). "<br/>"); Echo (Date ("L DS \of F Y h:i:s A"). "<br/>"); Echo ("Oct 3,1975 is on a". Date ("L", Mktime (0,0,0,10,3,1975)). " <br/> "); Echo (Date (date_rfc822). "<br/>"); Echo (Date (Date_atom,mktime (0,0,0,10,3,1975)). "<br/><br/>"); Echo ("Result with Gmdate (): <br/>"); Echo (Gmdate ("L"). "<br/>"); Echo (Gmdate ("L DS \of F Y h:i:s A"). "<br/>"); Echo ("Oct 3,1975 is on a". Gmdate ("L", Mktime (0,0,0,10,3,1975)). " <br/> "); Echo (Gmdate (date_rfc822). "<br/>"); Echo (Gmdate (Date_atom,mktime (0,0,0,10,3,1975)). "<br/>");? >
