memcached -h
memcached 1.4.5
-p TCP port number to listen on (default: 11211)
-U UDP port number to listen on (default: 11211, 0 is off)
-s UNIX socket path to listen on (disables network support)
-a access mask for UNIX socket, in octal (default: 0700)
-l interface to listen on (default: INADDR_ANY, all addresses)
-d run as a daemon
-r maximize core file limit
-u assume identity of (only when run as root)
-m max memory to use for items in megabytes (default: 64 MB)
-M return error on memory exhausted (rather than removing items)
-c max simultaneous connections (default: 1024)
-k lock down all paged memory. Note that there is a
limit on how much memory you may lock. Trying to
allocate more than that would fail, so be sure you
set the limit correctly for the user you started
the daemon with (not for -u user;
under sh this is done with ‘ulimit -S -l NUM_KB’).
-v verbose (print errors/warnings while in event loop)
-vv very verbose (also print client commands/reponses)
-vvv extremely verbose (also print internal state transitions)
-h print this help and exit
-i print memcached and libevent license
-P save PID in , only used with -d option
-f chunk size growth factor (default: 1.25)
-n minimum space allocated for key+value+flags (default: 48)
-L Try to use large memory pages (if available). Increasing
the memory page size could reduce the number of TLB misses
and improve the performance. In order to get large pages
from the OS, memcached will allocate the total item-cache
in one large chunk.
-D Use as the delimiter between key prefixes and IDs.
This is used for per-prefix stats reporting. The default is
“:” (colon). If this option is specified, stats collection
is turned on automatically; if not, then it may be turned on
by sending the “stats detail on” command to the server.
-t number of threads to use (default: 4)
-R Maximum number of requests per event, limits the number of
requests process for a given connection to prevent
starvation (default: 20)
-C Disable use of CAS
-b Set the backlog queue limit (default: 1024)
-B Binding protocol – one of ascii, binary, or auto (default)
-I Override the size of each slab page. Adjusts max item size
(default: 1mb, min: 1k, max: 128m)

use

preg_replace("/<!--.*?-->/ms","",$str);
or

$test = "<!--my comment goes here--> Hello World <!--------welcome-->welcome";
echo  preg_replace('/\<.*?\>/','',$test);

or


preg_replace('/<!--(.*)-->/Uis', '', $html)

this is fun code must works!

This code tracks visits to your site 15 different bots. Naturally, the list can be extended – is represented by no means all of the existing ones.

Use it, you can read: let’s say your site has a template, and its “assembly” used files header.php ( “cap” of the site) and footer.php ( “basement”). Typically, these files are inserted at the beginning and end of each page on your site.
To carried out statistics on the Hits In of SE bots in this case, you must add the file header.php following code:

include("bot.php");

Now all the bots will be tracked and kept locked in a file bots.txt on your server.
PS. Do not forget to change CHMOD of bots.txt to 777
