There is a large string:

GroupWise, I personally expected the desired drive bit discard weapon read the drive bit fog lamp expected 12321321321 dadada


How to extract the time?

PS: If regular expressions are not used. Is there any str function?

------ Solution --------------------
/(\ D +-\ d + )/
------ Solution --------------------
$ Str = "Awesome! I personally expected the desired drive bit discard weapon read the drive bit fog lamp expected 12321321321 dadada ";
$ Pattern = "/(\ d {4}-\ d {1, 2}-\ d {1, 2 })/";

Preg_match_all ($ pattern, $ str, $ matches );
Echo'

';
Print_r ($ matches );
?>
------ Solution --------------------
The string method is too limited. '-' cannot appear before the date. use regular expressions.

 
 

  
  
PHP code

  
  
$ Str = 'awesome group' I personally expect the desired drive bit discard weapon 2011-12-12 read the drive bit fog lamp expect 12321310921dadada '; $ position = strpos ($ str,'-')-4; echo substr ($ str, $ position, 10 );
