I know of an open source package which uses services hosted by VeriSign
and MBlox. These cost a pretty penny, though, and may not be what you're
after.
The services give you a private channel for your users to interact with
you, and for you to (potentially) respond to them.

You're looking for SMPP packages.

HI,

The vast majority of carriers have a free to use email to sms gateway for
their clients phones.

There is a list of each carriers format for the email address. Have someone
select the carrier in the form when entering the phone number then you have
it sent to the email as specified by the carrier.

The thing with SMS is volume. Most commercial (bulk SMS) service
providers do provide a return path at a price, but this can get really
expensive especially at low volumes.

What you need to do is ask yourself whether you are going to do high
volume SMS or not, and look at when do the commercial providers become
more economical? What a lot of people do, is sign up for an account and
end up sending only 50 or so SMS a month, which is silly, when for the
same price as a month or two's subscription, you could buy your own GSM
modem and a prepaid SIM card and do it for half the price yourself.

Or use sms_client and only pay per individual SMS. No subscription
needed.

What file handle? preg_match doesn't work on resources, it works on data.

What do you mean by die? return no results? segfaults the server? .... ?

This is probably your problem, you are trying to match on a resource
handle, not a string or something.

Check out http://www.php.net/preg_match_all

> the regex is valid

Won't really matter if the data is in the wrong format!

Just a follow-up on this, the problem was 'Fatal error: Allowed memory
size of 8388608 bytes exhausted'

After some nice help, I found that this is actually a common problem
with intense regexes in php. Quick fix is using ini_set() to increase
your memory_limit to something massive, like '400M'. This gives your
script access to that much memory for its life-time. If you have this
problem, then you probably also have to do this

set_time_limit(0); //remove any max execution time

Increasing the memory limit is the worst possible solution to this
"problem".

It's a giant file, and your regex is basically pulling out each line.
For the love of $DEITY learn about fgets and process each line one by
one rather than loading in the whole file. It'll be a lot faster and
won't suck your memory dry while it runs.

Can you also post a few lines from your access log so we've got
something to test against.

The regex looks incorrect to me in a few places:
-\d+] {1,4}
for example.

How to debug your script:

make a copy of the log file and trim it down to say 20 lines; run the
script on it to verify it's doing what you want it to.

check the size of the "real" log file, then multiply it by 2.5 and see
if the total is greater than your php max memory setting. (exp: $theData
will hold the full file, matches will also hold another copy of most of
the file, then a bit extra for php to use)

That's ok, albeit confusing:

* The ']' is a literal ']' not the closing bracket of a character class.
* The {1,4} applies to the space character.

Define "fail"...

There are any number of things that could be going wrong.

Check your logs, dump out the data, etc

Looks like your on an old 4.x version of php; try the following.

<?php

I don't think it's that simple.

Have a good, clear contract and relationship with the client.

You can also attempt to "encode" them with any number of PHP encoders,

Consider the following code:

$sqlQueryInserimentoDatiAllenamentoCalciPiazzati = "INSERT INTO ... etc etc
...."
$queryInserimentoDatiAllenamentoCalciPiazzati =
mysql_query($sqlQueryInserimentoDatiAllenamentoCalciPiazzati);
if($queryInserimentoDatiAllenamentoCalciPiazzati) { // do something }
if($queryInserimentoDatiAllenamentoCalciPiazzati) {
$logQueryInserimentoDatiAllenamentoCalciPiazzati = mysql_query("insert
into log ... etc etc ...");
if($logQueryInserimentoDatiAllenamentoCalciPiazzati) { // do something }
}
if($queryInserimentoDatiAllenamentoCalciPiazzati &&
$logQueryInserimentoDatiAllenamentoCalciPiazzati) { // do something }

1st execution: $queryInserimentoDatiAllenamentoCalciPiazzati &&
$logQueryInserimentoDatiAllenamentoCalciPiazzati, where clause of last
conditional statement, evaluates to false even if both queries are correctly
executed.

I modify as follows:

$sqlQueryInserimentoDatiAllenamentoCalciPiazzati = "INSERT INTO ... etc etc
...."
$queryInserimentoDatiAllenamentoCalciPiazzati =
mysql_query($sqlQueryInserimentoDatiAllenamentoCalciPiazzati);
if($queryInserimentoDatiAllenamentoCalciPiazzati) { // do something } else
echo("error message 1");
if($queryInserimentoDatiAllenamentoCalciPiazzati) {
$logQueryInserimentoDatiAllenamentoCalciPiazzati = mysql_query("insert
into log ... etc etc ...");
if($logQueryInserimentoDatiAllenamentoCalciPiazzati) { // do something }
else echo("error message 2");
}
if($queryInserimentoDatiAllenamentoCalciPiazzati &&
$logQueryInserimentoDatiAllenamentoCalciPiazzati) { // do something }

2nd execution: $queryInserimentoDatiAllenamentoCalciPiazzati &&
$logQueryInserimentoDatiAllenamentoCalciPiazzati, where clause of last
conditional statement, evaluates to true.

Now, I modify again, back to the original version:

3rd execution: $queryInserimentoDatiAllenamentoCalciPiazzati &&
$logQueryInserimentoDatiAllenamentoCalciPiazzati, where clause of last
conditional statement, evaluates to true.

Do you know any reason for that?

How long does it take you to write a single line of code with variable
names like that?

Holy crap, so much for compact and clean code. It must take you
days to write a script! ;-P

In any case, there are a ton of syntax errors in your second block
of code. Missing closing brackets, semicolons, et cetera. It
shouldn't even compile (fatal errors).

Also, after rewriting all three blocks of code so that I could
read them without having a seizure, it looks like it's a problem with
your database. Unless you're actually trying to see if
$sqlQueryInserimentoDatiAllenamentoCalciPiazzati is true (in block
#2), which you just defined as an SQL statement, whereas you're trying
to see if $queryInserimentoDatiAllenamentoCalciPiazzati is true (in
block #3), which you just defined as a resource identifier.

In my opinion, variable names are a personal choice, I think the time you
loose when writing the name (about a second is long less than the time you
gain when, months later, you go and modify the code and you have clear the
content and meaning of each variable.

In the original code there were no sintax errors, I added some errors when
pasting here. Sorry.

I have found that in the first execution, it was the
$logQueryInserimentoDatiAllenamentoCalciPiazzati that evaluated to false.
After having removed the two-field key that I had originally defined for
that table and having added an autoincrement key, the problem seems to be
solved.

Do you find any reason for that?

Glad to see that you found your problem. Variables may be easier to read
with some underscores.

Personally, here is what I use as a counter in most all of my code,
instead of $i++; which isn't always clear.

$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter =
$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter +
($Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter /
$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter);

If you wan to shorten a bit you can use a constant as the counter
increment like so:

define('Increment_Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter', 1);

$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter =
$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter +
Increment_Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter;

When keeping track of patients at the local hospital we like to indicate
whether they have certain afflications.

$patient->pneumonoultramicroscopicsilicovolcanoconiosis = false;

You forgot to add the project name you are working on to the counter, this way
you'll never confuse yourself at all.

define('Increment_Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter_For_Project
_Spaghetti', 1);

$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter_For_Project_Spaghetti =
$Super_Cala_Fraga_Listic_Ex_Peal_Ado_Tio_Us_Counter_For_Project_Spaghetti +

hi people,

1. __autoload & APC

I have been STW to try and find a definitive answer as to whether using __autoload with APC
is a bad idea ... and if so why? ... I can't find that definitive answer, can anyone here
state whether this it's an absolutely bad idea to use __autoload with APC? (I need to
speed up an app that currently loads in pretty much everything on every request ... and it's
impossible to untangle the class interdependencies, in the time I have, and thereby load only
what is absolutely needed, when it's needed ... so I want to give __autoload() a shot in order
to minimize what classes are loaded.

2. webclusters & APC

I'm building a load-balanced cluster for the same app ... a certain times new data is imported
from a thirdparty system after which some APC cached data needs to be cleared, in the same vein
I occasionally roll out a new version and then the APC opcode cache needs to be cleared (each webserver
in the cluster has it's own APC cache obviously).

now I'm stuck with the problem of how to trigger the cache clearance on all servers ... Greg Donald
already mentioned the ruby based capistrano for executing commands on multiple remote servers and I'll
be using that to manage things like cache clearance, webserver restarting, etc on all the webservers

... BUT I have found that it is not possible to control the APC cache of php_mod from the CLI version of
php, they apparently use different APC caches. it seems that the only way to control the APC cache of
mod_php is via a web interface. APC ships with the very handy apc.php script but this is hardly a decent
way of controlling/clearing the APC cache of multiple machine programmatically.

Am I stuck with one of:

1. doing a graceful restart of all servers (which causes APCs cache to disappear)?
2. writing a cmdline script that performs a URL request to a copy of apc.php that is reachable via each
webserver in order to clear/manage the APC cache?

or is there another way that I can control the webserver's APC cache from the cmdline?

rgds,
Jochem

If it's that inter-tangled, then I would hazard a WILD GUESS that the
__autoload will still end up loading everything...

Yes, that should work.

Yes, but obviously password-protect it to avoid DOS.

One would think there would be some kind of USR_* signal that can be
sent through Apache to APC to clear cache...

but not on every request ;-) ... I do use output caching, and I know
not everything is actually used in every request.

I'm being optimistic and hoping it has a marginally positive effective on
average request processing time.

I know - but it's a rubbish solution because it offer no control as to what
is cleared from the APC cache, sometimes I want to clear opcodes, sometimes user-data,
sometimes both ... graceful means being forced to clear everything.

yeah - think this is the route I have to take somehow .. I'm going to look into
running a seperate vhost only available via 127.0.0.1, with a pwd on it and then
write a little script that can control the apc cache via said vhost from the
cmdline ... the cmdline script would then be controlled remotely via ssh using
the coolness that is capistrano (http://www.capify.org/)

One would think that there was something like this indeed - I cannot find it,
but then there must be something ... I assume, for instance, that Yahoo!** occassionally
see fit to clear APC caches on more than one machine and I doubt Rasmus sits there and
opens a browser to run apc.php on each one ;-)

** is it too early to say 'MicroHoo!' ?

The fact that you are seeing zero error messages indicates that you
almost for sure aren't checking the right places to find error
messages...

Figure out what's in your php.ini and get it to use E_ALL and send the
errors to a log or something.
