I want to execute a couple of linux commands from a php script
'sequentially in background'.
I want to run them in background so the php script doesn't hang while
the linux commands are running.
example:
first i create a lock file with php
$lockfile_path : /home/web/...blablabla.../test.tar.bz2_Lock.txt
the I execute the following command from my php script:
exec("du -a ~/ 2>&1 > /home/web/...blablabla.../backupFSlog.txt ;
sleep 10 >/dev/null 1>/dev/null 2>/dev/null ; rm -f $lockfile_path
>/dev/null 1>/dev/null 2>/dev/null &);
problem:
the php script hangs for 10 seconds (sleep), what is not what I want
I've read a lot of sugestions but I can't get it to work.
When I execute the commands one by one, it works in background, but
when I want to run them 'sequentially in background', the php script
hangs
They need to run sequentially because the $lockfile_path may only be
deleted when all the other commands are executed
Some advice please?

hi people,
PHP version: 5.1.1 (last built: Dec 28 2005 16:03:22)
APC version: 3.8.10
Apache version: 2.0.54 (last built: Dec 29 2005 14:04:16)
OS: debian
I have a script that runs via the cmdline, it's used to import/update data
in a database, after the script is run the APC cache needs to be cleared so that
that the new/updated data is visible on the website. to do this I call a static
method of my cache management class which effectively performs the following:
apc_clear_cache();
apc_clear_cache("user");
this used to work, but now it does not (atleast not on the cmdline; calling the
above mentioned method via a webrequest still works). I have not recently
updated
php, apc or apache, neither have made any changes to the php.ini configuration.
someone else may have updated the OS/system (and I can't rule out that .
to test the problem I ran the following code at the cmdline:
# php -r 'var_dump( ini_get("apc.enable_cli"),
apc_clear_cache(),
apc_clear_cache("user") );'
this is the output I get:
string(1) "1"
NULL
bool(true)
so apc is enabled for the cli, cache clearance seems to work but when I
checking the output
of the apc.php file (shipped with the apc package) I see that nothing has been
cleared; performing
the same apc_clear_cache() calls (by way of pressing the buttons on the page
output by apc.php) via
the webserver module *does* clear the cache.
it seems all of a sudden that the CLI and then apache SAPI are looking at
different caches -
running apc_cache_info() && apc_sma_info() on the commandline show nothing in
the cache whereas
viewing the stats produced by apc.php (via the webserver) shows plenty of stuff
in the cache (both
before and after running apc_cache_info() && apc_sma_info() on the commandline)
can anyone offer some help/idea/etc?
Another Thing:
===========================================================================
although the manual states that apc_clear_cache() should always return a boolean
calling it calling the function without any args *always* returns NULL. can
anyone say whether
this is a bug or a documentation problem?
My APC ini settings (as defined in a seperate apc.ini):
===========================================================================
; Enable APC extension module
extension = apc.so
[APC]
apc.enabled = 1
apc.shm_segments = 2
apc.shm_size = 128
apc.optimization = 0

Just replying to the list on this one 'cause I'm pretty sure you're on
it. :-)
AFAIK, with many caches the web server cache and CLI caches are
exclusive to each process. The APC manual seems to suggest that the CLI
cache is not connected to the web server cache:
From: http://ca.php.net/manual/en/ref.apc.php
apc.enable_cli *integer*
<http://ca.php.net/manual/en/language.types.integer.php>
Mostly for testing and debugging. Setting this enables APC for the
CLI version of PHP. Normally you wouldn't want to create, populate
and tear down the APC cache on every CLI request, but for various
test scenarios it is handy to be able to enable APC for the CLI
version of APC easily.

Hi John & all,
Thanks for your info.
I have 2 array which populated from MYSQL as shown below :
My program will update status in the temporary table according to
compare of 2 arrays, for example from 2 array below:
in $temptablearr = there 3 elements
in $currenttablearr = there 2 elements
If value different betweeen $temptablearr and $currenttablearr , the
status is change to 'update'.
If value are same between $temptablearr and $currenttablearr , no
action taken.
If there are new elements in $temptablearr and not found in
$currenttablearr, the status is change to 'new'
If there are elements found in $currenttablearr and not found in
$temptablearr , the status is change to 'deleted'
Anyone have any ideas or suggestion how to do this ? Thanks for your help.

freudian slip; I wish it was debian, it's actually a red hat machine,
dmesg gives this about the OS:
Linux version 2.6.14-1.1653_FC4smp
([EMAIL PROTECTED])
(gcc version 4.0.2 20051125 (Red Hat 4.0.2-8))
#1 SMP Tue Dec 13 21:46:01 EST 2005
it seems that someone installed selinux stuff on the machine recently -
does anyone know what (if any) effect this might have on the shared memory
usage/functionality [especially in relation to apc]?

I know in PHP 5 you can use stream_socket_client() and set the flag to
STREAM_CLIENT_ASYNC_CONNECT|STREAM_CLIENT_CONNECT which opens the socket
in a non blocking mode.
in php 4 you can use fsockopen and then set the socket to non blocking.
The problem with this is that the fsockopen blocks until it creates the
socket or times out.
I want to know if there is a replacement for fsockopen that attempts to
open a socket, but returns immediately instead of blocking or is there
another way to open a socket in a non blocking mode in PHP 4
thanks

Hi everyone.
Here i am again talking about fpdf.
In the last question Peter told me that i can set a folder to write a pdf
file by fpdf class but, to do that i ought to set permission to web user to
write in this folder and think it´s bad to security.
I thought a lot about it and then came back here to try to explain a little
doubt.
Could i write the pdf file into a temporary folder of php and then put it
into the right folder by ftp?
If yes, anyone could help me about that, something like; which folder can i
write the file?
Thanks a lot.

Hi all. I am about to start writing an events listing application
(nationwide) and want users to be able for example to specify events within
a 5, 10 and 15 mile radius of their postcode. Does anyone know of a set of
classes/library that can provide this, would rather not fork out on a
bespoke piece of kit. Any suggestions appreciated!

Hi gang:
From another list, a person posted:
"I want to use PHP's mb_substr() function to grab the first letter of a
UTF-8 encoded word (in Czech) being pulled out of MySQL. If I use the
plain substr()
the data gets garbled and I get a ? symbol in the browser.
My host says
that in order to get multibyte string functions I'd have to compile my own
copy of PHP. That's getting a little deeper than I want to for one function
on one page. Does anyone know what I could do as a workaround?"
I've tried to help, but it appears beyond me.
Anyone have any advice I could pass on?
Thanks.

In a couple of my scripts, I do something like the following when I detect
an improperly submitted form:
** if( !valid_string( $_POST['firstname'] ) )
{
$return_url =
"https://www.abc.com/checkout_phase1.php?error=FirstName Required";
header( "location: $return_url" );
exit(0);
}
Recently I changed the code so that a big variable that was being passed via
GET (IE, as a param in the URL) is instead being POST'd... (typically, via a
hidden INPUT elem in a form)...
Unfortunatley, this broke my error handling logic... Is it possible to add
POST variables to a redirect? How?

Use sessions. Store the variables you need in the session, then
redirect. After redirect get the values you need from the session.

Hello all,
this seems like an easy question, but I could sure as hell couldn't find any
responces to it through initial searched. I am running php on an XP system
and I need to open a file contained with a set of directories which may or
may not have a space character; so for example:
fopen ("X:\Dont Talk\About\My Momma\please.txt", "x");
I tried using \ characters, no luck (even attempted to cancel out the
backspace characters ala \\ and http space code %20, and still nothing.) Any
ideas?

RTFM -- you need to double backslash when using double quotes. Otherwise
use single quotes.

And after writing that I re-read and realized you did *hah*. Make sure
the file exists on the hard drive where you think it does. Also make
sure you have read permissions. And hwile you're at it, make sure you
have error reporting enabled so you can see any "special" errors that
might be issued for various violations.
Cheers,
Rob.

Spaces aren't your problem here, the \'s are. You need to escape them...
fopen ("X:\\Dont Talk\\About\\My Momma\\please.txt", "x");

I' trying to include files from a script which will be executed from CLI via
cron.
Now, if I execute the script from the command line it works OK, but when it's
executed via cron I fails to include a file, which is being included via and
include from the script. It looks like when including a file directories are
changes, and so the new include doesn't work as it's referencing from a
different directory.
Is there something I should be aware of?
