I really like the PHP function strtotime(), but the user manual doesn’t give a complete description of the supported date formats. It only gives a few examples like ’10 September 2000′, ‘+1 week 2 days 4 hours 2 seconds’, and ‘next Thursday’.
Where can I find a complete description?
I can’t find anything official, but I saw a tutorial that says strtotime() uses GNU Date Input Formats. Those are described in detail in the GNU manual.
One discrepancy I notice is that ‘next’ doesn’t match the behaviour described in the GNU manual. Using strtotime(), ‘next Thursday’ will give you the same result as ‘Thursday’, unless today is a Thursday.
If today is a Thursday, then
If today is not a Thursday, then
I’m using PHP 5.2.6.
Update:
I guess the user manual has been updated since I posted this, or else I was blind. It now contains a link to the Date and Time Formats chapter, that includes a section on relative formats.
