Sometimes  PHP will emit a X-Powered-By  response header which you can look at e g  using Firebug    If this setting  controlled by the ini setting expose php  is turned off  it often is   there is no way to tell the PHP version used - and rightly so  What PHP version is running is none of the outside world s business  and it s good to obscure this from a security perspective

Possibly use something like firefox s tamperdata and look at the header returned  if they have publishing enabled

By chance  Default error pages often contain detailed information  e g       Apache  Version    OS    Modules  PHP  Version   Modules  Server at  Domain    Not so easy  Find out which versions of PHP applications run on the server and which version of PHP they require   Another approach  only mentioned for the sake of completeness  please forget after reading  You could  but you won t   detect the PHP version by trying known exploits

You can   t  One reason is that not every web site uses PHP  And another reason is  Even if there are some signs that PHP might be used  e g   php file name extension  some    PHPSESSID    parameter  X-Powered-By header field containing    PHP     etc   those information might be spoofed to let you think PHP is used
