http://us2.php.net/manual/en/ref.shmop.php says: <<Note that versions of Windows previous to Windows 2000 do not support shared memory.>> I use Windows 2000. It's not <previous> and I've not found anything about emulation nor current enviroment. Sorry, that I don't know Windows enough to undestand that shmop CANN'T work on it properly. May be, there should be a note in manual?

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php SHM is emulated on win32 and the nature of the emulation that it would work only in a persistent environment such as Apache or IIS (not cgi or cli). ------------------------------------------------------------------------ [2004-02-16 23:13:57] yury at gorodok dot net sh.php <?php $shm_key= 111; $str="I was here."; $shm_id= shmop_open($shm_key, "c", 0644, strlen($str)); if ($shm_id== false) echo "I was unable to create shmop!<BR>"; else { $wrb=shmop_write($shm_id,$str, 0); if($wrb!= strlen($str)) echo $wrb." bytes was written of ".strlen($str)."!<BR>"; echo "shm_id=".$shm_id."<BR>"; shmop_close($shm_id);} ?> hh.php <?php $shm_key= 111; [EMAIL PROTECTED]($shm_key, "a", 0, 0); if ($shm_id== false) echo "Couln'd open shm <".$shm_key.">!<BR>"; else {$A=shmop_read($shm_id, 0, shmop_size($shm_id)); echo $A."<BR>"; echo "shm_id=".$shm_id; shmop_close($shm_id); } ?> hs.php <?php $shm_key= 111; [EMAIL PROTECTED]($shm_key, "a", 0, 0); if ($shm_id== false) echo "Couln'd open shm <".$shm_key.">!<BR>"; else {$A=shmop_read($shm_id, 0, shmop_size($shm_id)); echo $A."<BR>"; echo "shm_id=".$shm_id; shmop_delete($shm_id); shmop_close($shm_id); } ?> ------------------------------------------------------------------------ [2004-02-16 11:23:13] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2004-02-16 03:42:54] yury at gorodok dot net Description: ------------ shmop doesn't work properly. I start sh.php, which creates shmop segment and write a strring there. After that I start hh.php, which should read string and write it in my browser. The hs.php deletes segment. On FreeBSD with PHP 4.3.4(apache module and command line) this works just fine. But on Win2000SP2 with PHP5.0.0b4(commandline and cgi) I can access shared memory segment only while the first script is running (I' ve adde sleep(30) in it for test reasons). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27271&edit=1
