Re: [PHP] Basic question - Starting a background task without waiting for its end.
2006/12/31, Michel <[EMAIL PROTECTED]>:
I (very simply) try to open a "notepad" on a simple text file in a
simplistic PHP script, and would like to go on and display the next page
without waiting for this notepad to be shut.
After various attempts, I have used an :
exec ('bash -c cmd /C start /MAX notepad "my_file" > NUL');
... but it still wait for the shutting of the notepad ..!
Could anybody help me ?
For clarification :
1) I use this script on a machine which is in the same time "server" and
"client", which gives "meaning" to this operation.
2) I use "bash -c" because I have the cygwin platform which can easily
initiate tasks in background, but it could be suppressed, because it "de
facto" changes nothing...
Thank's for help.
Michel.

It doesn't seem to be working for anyone (me neither btw)... why not use a simpler approach? Here's an example that doesn't use a redirect. Due to using the onload mechanism we can be certain that the order of the updates to the session occurs in expected order (if javascript is enabled) which is as we want.

Binary mode ("rb") doesn't mean PHP will translate each bit of the data
into a 7-bit (or longer) textual representation.

[PHP] Writing Binary
Hello Everyone,
I'm trying to write a PHP script that opens a binary file, reads the
binary in chunks, checks those chunks for a certain binary string, and
then if the string is found, it replaces the string with another binary
string. The script should then a copy of the file, including the
changed bits. But for some reason, the script is not replacing the
binary string.
Here's the source code:
if
(eregi("01010011011101000111001001110110111001100111011001010111010001100111011101101110",$buffer))
{
$buffer2=eregi_replace("01010011011101000111001001110110111001100111011001010111010001100111011101101110","01010110011010010110001101110100011001110010011010010111",$buffer);
}
else
{
$buffer2 = $buffer;
}
fwrite($out,$buffer2);
}
fclose($out);
fclose($in);
print("About ".($count*5)." bytes read.\n");
?>
The resulting file is not changed at all, the size, md5 sums, and
contents are the same as the original file. The original file is only
40,960 bytes on the disk, so the script reads the file in one pass. I am
sure the binary string is in the original file, and I have tried reading
the file into chunks as small as 64 bytes. I am at a loss as to what is
happening, so I would appreciate any help.
Sincerely,

Detecting a user's geographical location is a bit hit and miss, but there are some databases (both free and paid for) that you can use to map an IP address to a country and at that level it's usually fairly accurate (the further you try to narrow it down, the less accurate your results will be). Have a look at these databases, and a search for 'geoip' or 'libgeoip' on Google should get you some more results: http://www.hostip.info/ http://www.maxmind.com/app/geoip_country Hope this helps.

[PHP] [PHP-DEV] Semaphores - feature request
It's impossible to correct remove semaphores with sem_remove function
when I use them to provide execution of concurrent processes.
When the last process releases the semaphore I should be able to remove
it. But I don't know if another process haven't acquired the semaphore.
For safety reasons I don't remove released semaphores from system.
Now, If I get 128 semaphores and I execute sem_get one more time I will
get warning.
So, I can't remove semaphores (because I don't know if another process
is using it) and I can't get next semaphore.
I will try to tell about my sugestion.
I assume that I have a function my_sem_remove($sem_id):
function my_sem_remove($id) {
if(Semaphore $id isn't acquired and its FIFO is empty)
sem_remove($id);
}
None of instructions in this function can be interrupted.
So, now the problem is simple to resolve:
$id = sem_get(ID);
sem_acquire($id);
CRITICAL REGION
sem_release($id);
my_sem_remove($id);
But now, two instructions: sem_release and my_sem_remove are not needed.
It's simple to replace them by one function my_sem_release:
function my_sem_release($id) {
sem_release($id);
my_sem_remove($id);
}
For reasons which about I will write later those instructions can't be
interrupted.
So, my example look like this:
$id = sem_get(ID);
sem_acquire($id);
CRITICAL REGION
my_sem_release($id);
But let's imagine two concurrent processes executing code above:
PROC1: $id = sem_get(ID);
<--- interrupt
PROC2: $id = sem_get(ID);
sem_acquire($id);
CRITICAL REGION
my_sem_release($id);
<--- interrupt
PROC1: sem_acquire($id); <--- Uuups!! Error: semaphore doesn't exists,
PROC2 has removed it.
My solution:
Instructions sem_get and sem_acquire can't be interrupted.
So, I assume that there is a function my_sem_acquire:
function my_sem_acquire($key, $max_acquire = 1, $perm = 0666,
$auto_release = true) {
$id = sem_get($key, $max_acquire, $perm, $auto_release);
sem_acquire();
return $id;
}
None of instructions in function above can be interrupted.
And finally correct example:
$id = my_sem_acquire(SEMKEY);
CRITICAL REGION
my_sem_release($id);
It's the best solution, without danger of operating on not existing
semaphores. Also, unused semaphores are automaticcally removed. The
problem is, that functions my_sem_acquire and my_sem_release can't be
witten in PHP so it must be done in C inside source of PHP.Wojciech Malota
