You can't, phone numbers are more complex then that. You could use
\d{3}-\d{3}-\d{4} to match that basic pattern for all numbers though.

Hi List.
I've mentioned before that I am both just beginning to learn PHP AND I have
inherited a number of pages that I'm trying to clean up the w3c validation on.
Something that confuses me is how the code on the page is written where in
one instance, it follows this:
echo table border='1'tr
And elsewhere on the page it follows:
echo 'table border=1tr
In what I've read and from many of the suggestions from this board, the
latter seems to be the better way to code, generally speaking.
So given that the page has javascript in it, perhaps the reason for the
previous developer switching between the two was for ease of incorporating
JS? Don't really know... but what I would like to know is it considered
poor coding switch between the two on a single page or is it perfectly
acceptable?
2nd question, in the 3 lines below:
$_SESSION['newpage'] = $newpage;
$checkstat = select field from table where fieldid = $field_id;
$result1 = @mysql_query($checkstat,$connection) or die(Couldn't execute
query);
If I were to recode in the latter style, should they not look like this:
$_SESSION['newpage'] = $newpage;
$checkstat = 'select field from table where fieldid = '.$field_id.'';
$result1 = @mysql_query($checkstat,$connection) or die('Couldn\'t execute

The focus being here:
'.$field_id.'';
('Couldn\'t execute query')
Is this correct?

It is generally accepted that you should use single quotes whenever possible. I
only use double quotes when writing SQL queries (so I don't have to continually
escape them for the single quotes) and when I need to output control characters
like \r or \n.
It would be considered best practice to make consistent use of them, but it
wouldn't be something I would loose sleep over.

Re: [PHP] Meta HTTP refresh problem
Recently, during a rewrite of my login page, the Meta Refresh I am using
suddenly stopped working. I've tried using it by echoing it with php and
by just using it in HTML. I've also tried using a javascript redirect
with no luck either. Any thoughts on how to debug and what might be
holding me up?
[snip]
//Test to see if you actually got to this part
echo You should be going somewhere!;
echo META HTTP-EQUIV=REFRESH CONTENT=\0;URL=main_page.php\;
} else {
printLogin();
echo brcenterInvalid username/password/center;
}
META tags have to go in the HEAD section of the HTML document.
this is an optional suggestion but, overall, one thing that would be
better is to determine (before you send any ouput) if the login was
correct or not, and if not, use an HTTP redirect:
if (bad login) {
header(Location: http://mydomain.com/login.php?tryAgain=1;);
} else {
header(Location: http://mydomain.com/mainpage.php;);
}
(the tryAgain=1 is to tell the script that you want to show a
login failed, please try again message)
using a redirect instead of a meta refresh is more user friendly because
(1) it's faster since some browsers force a waiting period before the
refresh happens (as a usability feature), and (2) the user can use
back/forward without running into the this page contains POST data, do
you want to resend it? alert, which I avoid in my designs like the
plague (always using a redirect instead of showing output as the result
of a POST action).

Re: [PHP] header(Location: page.php target=_parent)?????
How should I formulate the header function to replace the current frameset page with a new one? I have tried a combination of header(Location: page.php target=_parent); but I get an error message saying the page does not exist. Also, can I save a frameset page with a .php extension? I have tried it out and it seems to work. Maybe perhaps I should not do this as there may be some implications later on??? you cannot replace the main frameset using HTTP headers in the individual frame pages. HTTP headers do not allow for this because frames are a feature of HTML, not HTTP. therefore you must use HTML or javascript techniques to get a single frame to change the overall frameset. however, for what it's worth, you can replace the main framset using a header in the main frameset page itself, if you make that a php script and use the header() function.

Re: [PHP] Re: Getting the process ID
The problem I am having is that people are double-submitting certain transactions. My first attempt to prevent this was to store a flag in the session record indicating whether or not certain transactions had been completed, but this turned out to be insufficient at times because users could try and initiate a second transaction before the first transaction had finished (and thus the system had not yet flagged the transaction completed in the session record). They then both completed in parallel, and voila, duplicate transactions again. I realized that this sort of problem would always exist unless I had some sort of semaphore mechanism. Once a user has *started* a transaction, they need to be prevented from initiating a second transaction until the first transaction has been completed. I am open to suggestions on how to do this. What is the best way? do you have access to a database? why not just manage the transaction on the database level? transactions, locking, etc. are a core part of what databases do for a living. it's not a problem best solved with PHP. /josh w -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

To this you might also add an MD5 hash to check for authenticity,
depending on what you're doing with that incoming data that you're
unserializing (consider an client who sends you a serialized array that
you didn't intend). You'll also want to encode the serialized data with
htmlentities:
$serialized = serialize($testArray);
$hash = md5($serialized . my secret phrase);
echo 'input type=hidden name=serialized
value='.htmlentities($serialized).'';
echo 'input type=hidden name=hash value='.$hash.'';
then on the receiving end:
if ($_POST['hash'] != md5($_POST['serialized'] . my secret phrase) {
// the hash doesn't match up, consider the data unusable
} else{

with the SQL itself, you'll have unexpected failures and also a security

to wrap any strings or untrusted input like that in a call to

SO, does anyone have some code that uses MySQL to replace PHP's native
session storage that also correctly handles this concurrency problem?
Ideally I'd like to see just a set of functions that can be used with
sessions_set_save_handler() to transparently shift PHP's sessions to a
database, but I'm not going to use the stuff I've found on the web or
even in books (appendix D of O'Reilly's Web Database Applications with
PHP MySQL publishes code with this problem).
MySQL's InnoDB supports row-level locking. So row the right row in
session_start and release it in session_close function.
But mysql does not support nested transactions. Locking the row means
that your entire script has to happen inside a single transaction.
Since my application logic requires transactions as well, it would mean
using two separate connections to MySQL, one for the session transaction
and one for business transactions, and that means twice the connection
overhead.
In MyISAM you can use application-level locking: GET_LOCK() and
RELEASE_LOCK() in session_start and session_close, respectively.
Parameter would be session id with some prefix.
AH! GET_LOCK() - that would do the trick! I didn't realize MySQL
supported locking mechanisms independent of transactions/tables etc.
The problem is when you need to create session id - you must lock the
whole table to find unused session id and insert it into table.
Hmm... couldn't I just do an 'insert ignore' with the session id every
time to kick off the process? Then MySQL would handle checking for an
existing row and create an empty one if it didn't exist. A very stripped
down example:
To open a session:
1. insert ignore into sessions (id,content) values ($sess_id,'')
2. select get_lock('my_prefix_.$sess_id, 15)
3. if NULL returned then abort, otherwise lock is aquired OK
4. select * from sessions where id=$sess_id
Do stuff ...
To close it:
1. update sessions set content='...'
2. select release_lock(my_prefix_.$sess_id)
I don't have all the details covered yet but I think that is just
what I needed. Thanks!!

Solving the race condition at session layer will only make your application un-responsive.

However, my goal is simply to have a transparent, database-driven replacement for PHP's native session handler. I don't want to change my application logic because I'm switching session handlers - my application shouldn't care! And so, transparently reproducing PHP's session layer functionality is going to mean locking concurrent requests out, because that is what PHP's session handler already does (for good reason IMHO). you're argument about slow frames is valid, but is ALSO applicable to PHP's native session handler, e.g. i'm not introducing a new problem. the trouble can be mostly avoided in either case by not starting session in frames that don't need it (most of them), and doing any session stuff right away and calling session_write_close() ASAP to free up the lock so other frames can run. you're right that i could change my application logic to deal safely with concurrent requests from the same session, but PHP already nicely defeats the issue so you don't have to worry about it, and at a more or less negligable performance loss if you design the scripts to reduce session open/locked time to the bare minimum... i would speculate that the reason i haven't found a readily available solution is because most folks either (1) don't understand the problem, or (2) don't think such a race condition is likely enough to warrant a fix, or (3) are using a different backend (oracle, etc.) that makes the problem easy to solve. the PHP team, however, clearly thought it was important enough as is evident by their session handler design. ...have i convinced you yet of the worthiness of this endeavor? :) /jw -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Take the following code: ? session_start(); if (!isset($_SESSION['count'])) $_SESSION['count'] = 0; $_SESSION['count'] = $_SESSION['count'] + 1; sleep(5); echo htmlbodyh1Current count:; echo $_SESSION['count']; echo /h1/body/html; ? Open up two browser windows/tabs and load this page in both, try to make both pages load at the same time. Notice the second request takes 10 seconds while the first takes 5. That's because the second one is really, actually, indeed WAITING for the first one to finish. (You may have to do a first initial request before trying this to get the cookie set.) This also is not a side effect of web server processes, threading, etc., it's really waiting until the session lock is released. No request should be blocking (i.e. wait for concurrent processes to execute). This implies a poor understanding of transactional processing from both yourself and PHP! On the contrary, when dealing with a session store (in PHP, which AFAIK always writes the session and the end of the request), it's very important for serial access instead of concurrent. Take the following sql from two MySQL clients: client 1: start transaction; client 2: start transaction; client 1: select * from mytable where id=1 FOR UPDATE; # i.e. give me the data from the row with a write lock client 2: select * from mytable where id=1 FOR UPDATE; ... client 2 is going to have to sit there and wait until client 1 commits or rolls back. that's how it should work with the session store. each PHP request should acquire a write lock on the session so no other request can even *read* the data until the original request is done. - You usually only store some kind of identification for a user in the session - no other data. doing otherwise is dangerous as there are multiple copies of data floating around uncontrolled. A session-id is enough information to store. Don't use the session for storing data willy nilly - it is for identifying the session only - nothing else. Can't say that enough. Don't use it for shortcutting code. there is no point to storing only a session id in a session store. the session id is already in the cookie or querystring. what's the point of a session, then? tell me how you store a user's login status, a user's shopping cart contents, etc. - that is the place i call the session store and that is the thing that needs to block concurrent (write) requests, whatever you want to call it... - If you want a proper transactional system, there are two ways to handle concurrency: [snip] Personally, no-one in the PHP/MySQL arena tends to understand these concepts as the two technologies are rarely used for pushing data around on big systems (this is generally Java/Postgres' domain). i understand your explanations. in the case of session concurrency, if you're using a fail commit on change and are also using frames with PHP's session design, you're site just isn't going to work. one frame will appear and the rest will say sorry, some other process got to the data first. instead, each frame request has to wait for each other to finish, which is how PHP's native session handler does it. I ONLY use PHP/MySQL for knocking up quick web apps to fart out content - nothing serious because it's simply not suited. Have you checked out InnoDB? Row level locking, transactions, etc etc. Not as fully featured, agreed, but all the critical stuff is there. MySQL isn't the same as it was a few years ago. /jw -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] warning question about mysql sessions concurrency
I've been trying to switch to MySQL-based session storage instead of the native PHP session storage. In doing so, I've run into a lot of code on the web that exhibits a serious flaw regarding concurrent requests from the same client. All the code I've seen has glossed over the need to lock the session for the duration of the request, e.g. not allow concurrent requests to use it until it has finished. PHP's native session handler correctly does this, but lots of MySQL-driven session code does not. Example timeline: 1. client sends a request 2. session data is loaded from the db 3. same client sends a request before the first one is finished (e.g. frames, tabbed browsing, slow server response times, etc) 4. session data is again loaded from the db 5. the first request changes some values in $_SESSION 6. the second request changes some values in $_SESSION 7. the first request writes the data to the db and exits 8. the second request writes it's data (over that written by the first request) and exits PHP's native handler solves this problem by forcing concurrent requests to wait for each other. The same thing needs to happen in a database-driven session handler. SO, does anyone have some code that uses MySQL to replace PHP's native session storage that also correctly handles this concurrency problem? Ideally I'd like to see just a set of functions that can be used with sessions_set_save_handler() to transparently shift PHP's sessions to a database, but I'm not going to use the stuff I've found on the web or even in books (appendix D of O'Reilly's Web Database Applications with PHP MySQL publishes code with this problem). Folks using database sessions who do not deal with this scenario be warned! I'm surprised so much bad code is going around for this task...

Re: [PHP] On large application organization [long and possibly boring]
Josh, I am interested in what you mean by but there may be a better overall approach. (which was in reference to my original question which was: why are you using a big switch?) The reason I say that is because, though I'm no expert on application design, in my own code I've found that whenever I'm tempted to use a big switch, it's probably a better idea for me to make a class hierarchy. I just have a hard time imagining a case where a big switch accurately represents the problem to be solved, since in real life solving problems is more complicated than a flat set of totally isolated operations. For example, a while ago I wrote some form validation code for a classifieds application that used a 50+ case switch to validate incoming form data, one case for each possible kind of field (make model, price, location, color, etc). There was a large amount of overlapping functionality for similar field types and it was also hard for me to understand exactly what the start and end goal was for all the cases. If some common thing needed to be changed, most or all the cases had to be updated and kept consistent, and by the 45th case my brain is going to miss something. Now I'm not suggesting this is what you're doing - this is just bad design on my part. Currently I'm in the process of implementing a class hierarchy of fields, where for example the make_and_model class inherits from the drop_down parent class, which inherits from the basic_field class, each one extended or overriding it's parents validate() method. If I need to update the way drop downs validate, I make a change in the drop_down class and it propagates naturally to all the instances and subclasses. A much better method than my earlier switch! So, because I feel like I've learned a bit personally about avoiding big switches I was curious about your approach, which I say again could be perfectly elegant :) /jw -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] On large application organization [long and possibly boring]
If I have a large app what is the difference, other than having a very
large file, of doing this
switch($action){
/* several dozen cases to follow */
case foo:
writing out all of the code
break;
}
and this
switch($action){
/* several dozen cases to follow */
case foo:
include that will handle processing this case
break;
}
Correct me if I am wrong, but includes (and/or requires) will get all of
the code in all of the cases regardless if the case is being processed.
That being the case the code would essentially be the same length. Given
that, would there be an efficieny issue?
This would (the second way) also make the project easier to work on by
multiple programmers at the same time, similar to modular work being
done by programmers on C++ projects.
Correction: include() statements are executed at *run time*, which means
that if the case is not executed, the include will not be executed and
the file is not even read! The include() method is not only more
efficient but also easier to maintain as you suggest.
Otherwise, I'm curious as to why you're using a large switch, not that
it's bad inherently IMHO, but there may be a better overall approach.

Re: [PHP] Persistent PHP web application?
Anything you do in the MINIT hook is basically free, so it would be trivial to load the data for the array from somewhere. Like a database, an xml file, etc. So you wouldn't need to hardcode a complex array structure in your MINIT hook, just have this generic little extension that creates an array (or object) from some external source. To change the data you would change that external source and restart your server, or you could write a PHP function in your extension that forced a reload with the caveat that each running httpd process would need to have that function be called since your array/object lives in each process separately. If you ask really nicely one of the folks on the pecl-dev list might just write this thing for you. Especially if you spec it out nicely and think through how it should work. -Rasmus Call me crazy or ignorant, i'm both, but would it be possible to build an extension that, in its MINIT hook as you suggest, actually runs a separate PHP script that contains global definitions, then makes those definitions available to later scripts? this is basically my original desire of having a one-time, persistent global include for each apache process. i realize you suggest pulling array data from a source like a DB or XML file, which would be a 90% solution for me, but the next step (a PHP script) just seemed logical/exciting... i realize i'm reaching with this, and it implies a conundrum (how does an extension run a PHP script if PHP hasn't fully started yet) but this kind of thing is just what makes me go and learn new things (C, php/zend internals) and I just might try to do it if it was feasible, for the fun of it, because it could be useful to lots of people, even if it took me a year or two to pull off. alas, this is a question for the pecl-dev list.

Re: [PHP] Persistent PHP web application?
I think I understand where you're coming from. I've had a similar problem and the best solution I've found is eAccelerator (previously known as Turck MMCache). What EA does is keep the bytecodes PHP compiles inshared memory so next time you need that script PHP doesn't need to recompile, EA returns the bytecode from SHM. Now, since PHP scripts are compiled and saved in SHM all I need to do is /save/ the data that does not change often but requires a lot of queries as code (an array inside a script) and include it whenever I need the data. No recompiling, no need to touch the DB again, pure speed. I hope all this helps you. I personally don't need extra processes and stuff like that but if you really want all that you can take a look at phpbeans. Hope it helps, Adrian Madrid phpBeans looks interesting. after browsing the site a bit, looking at the introductory material and so on, i couldn't discern the way the phpbean server persists the beans, and, hence, if the solution would be fitting for what i'm looking for. what i'm looking for is a solution that will keep compiled zend variables and functions (the end result of executed php code that defines the variables and functions), in memory, without serialization, across multiple requests. if this is how the beans are kept persistent, i'm interested :) i'm going to try to find someone at phpbeans who can answer that. if others are interested, email me and i'll let you know what i find (if/when i find it)... /jw -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Slightly off topic but worth mentioning is:
If your $products array is generated dynamically, make sure it isn't
empty before running the query, MySQL does NOT like:
SELECT product_name FROM accessories WHERE product_id IN ()
The empty () will cause a MySQL error (it won't just return an empty

Re: [PHP] apache 1 vs 2 w/php

Re: [PHP] Persistent PHP web application?
Wow thanks for the helpful breakdown. PHP's model is to be completely sandboxed such that every request is completely separate from every other. Having a persistent interpreter as you describe would break that rule and break the infinite horizontal scalability model of PHP. Understood. A persistent interpreter is a whole different approach. I appreciate your perspective on that, it helps me to reconsider overall what I'm doing and why I want to do it :) Of course, there is nothing that prevents you from storing persistent data somewhere more permanent. If it is just simple read-only data you have a lot of options. For example, you could put them in a .ini file that is only loaded on Apache startup and use get_cfg_var() to fetch them. If you compile PHP with the --with-config-file-scan-dir switch to configure a configuration scan directory you can just drop your own ini file in that directory and it will be read on startup. This is just key=value pairs and not PHP code, of course. I'm dealing with large multidimensional arrays, like this: $categories = array ( 1 = array ( 'name' = 'Autos', 'depth' = 1, ... :( If you need to do something fancier you can stick things in shared memory. Many of the accelerators give you access to their shared memory segments. For example, the CVS version of pecl/apc provides apc_store() and apc_fetch() which lets you store PHP datatypes in shared memory directly without needing to serialize/unserialize them. That pecl/apc feature sounds like a great, cheap solution to my giant global variable definition problem, which takes the biggest single chunk of parsing time. The key AFAICS is avoiding the (un)serialization time. I'd love to see an example if you have one, just to show me a target to aim for. I'm unfamiliar with C / reading C source code and with shared memory so I'm having a tough time figuring out how to use that feature. (It doesn't solve the function definition problem but that is OK - the functions take FAR less time to parse than the global variable definitions.) And finally, the big hammer is to write your own PHP extension. This is a lot easier than people think and for people who are really looking for performance this is the only way to go. You can write whatever code you want in your MINIT hook which only gets called on server startup and in that hook you can create whatever persistent variables you need, pull stuff from a DB, etc. At the same time you will likely want to pull some of your heavier business logic identified by your profiling into the extension as well. This combination of C and PHP is extremely hard to beat performance-wise regardless of what you compare it to. This is something I'm VERY interested in. It is encouraging to hear that it is easier than I expect, and I will look into it further. Based on the responses from the list I've gotten, this seems like the most promising total solution.

Re: [PHP] Re: Persistent PHP web application?
Why don't you just create a daemon started from the command line (shell/DOS) and have it accept socket connections from your Web server PHP scripts and provide a SOA (Services Oriented API) to the code that accesses your data structures pre-loaded in memory? Setting up a separate persistent daemon PHP script is appealing to me because It implements exactly what I want, which is a persistent PHP application server, and also would allow me to abstract the implementation behind an API, move it to other servers when load increases, etc. However, would a single process PHP server daemon be able to appropriately handle the incoming load from Apache, which will be running multiple processes handling concurrent incoming requests?

Re: [PHP] Persistent PHP web application?
Thanks for taking the time for your comprehensive repsonse! However, given your programming philosophy so far, and the fact that you are worried about 7ms and that you specifically requested some kind of shared memory space in PHP, you should Read This: http://us4.php.net/manual/en/ref.sem.php That pretty much is exactly what you asked for. Be forewarned that few PHP scripters have needed this stuff, and it's not anywhere near as hammered on (read: debugged) as the other options above. I had the thought of using shared memory but I've found a scarce supply of introductory material and examples on the subject. The documentation assumes a level of familiarity with shared memory that I don't have, so I'm struggling. Examples of how to store and retreive a set of large multidimensional arrays to/from shared memory would be wonderful to look at, if you have some pointers to articles/books/etc I am also curious if the the shared memory solution would be a significant performance improvement, since, AFAIK, the data is serialized/unserialized for storage/retreival. Since the Zend Accelerator already uses a shared memory cache for the intermediate code, would using my own shared memory be any different? Consider that my global variable definition scripts are nothing more than giant unserialize statements. (Incidentally, I've benchmarked the difference between big unserialize statements and big PHP code array definition statements and found almost no difference, only a marginal improvement in performance using PHP code instead of unserialize on long strings.) Additionally, there are a large number of function definitions (more than 13,000 lines of code in all just for these global definitions). You should look into breaking these up into groups of functionality -- I'm willing to bet you could segment these and have many pages that only call in a few functions. That is good practice, I know i've been a bit lazy in that respect :) However, it is the variable definitions (big arrays) that take the most significant time, executing all the function definition code is actually only a small fraction of the time taken to parse the arrays, so it's a secondary concern, though you are right I should sit down and rework my includes so I'm only bringing in what I need. I'll set aside a week for that :) So if what your application mostly does is load in all this data and respond to requests, you could write a *SINGLE* PHP application which listened on port 12345 (or whatever port you like) and responded with the data requested. Like writing your own web-server, only it's a _-server where you get to fill in the blank with whatever your application does. Please see my repsonse to Manuel Lemos and his suggestion to run a SOAP server. Basically my concern is the lack of having a multi-process/forking server to handle concurrent incoming requests (which may or may not be a problem - not sure). We're talking about a persistent PHP server (SOAP or otherwise), and I'm having trouble groking how that would work in an environment with many concurrent requests. (Other than, of course, running a PHP SOAP server inside Apache which brings me back to square one :) Actually, Zend and others could be interested in your comparisons of with and without cache... If folks are interested in my benchmarks I could spend some time and put together a summary. Incidentally I did end up doing some comparison of cached code and uncached code because I unwittingly had the accelerator turned off for while until I realized it :) Hope that helps...

Re: [PHP] Re: Persistent PHP web application?
However, would a single process PHP server daemon be able to appropriately handle the incoming load from Apache, which will be running multiple processes handling concurrent incoming requests? I don't think you've quite got the right picture here... When you write your single process PHP server daemon, Apache's not even in the same picture frame any more. The requests aren't coming from Apache -- PHP is listening to a port you select, exactly in the same way that Apache listens to port 80, MySQL listens to 3306, your SSH server listens to 22, your Mail server listens to 25, your FTP server listens to [I forgot]... In other words, you are giving PHP a promotion from a Module of Apache, to being its own web server, only it won't be a web server, it will be a Whatever You Want server. I'll call it WYW (Whatever You Want) for the rest of this post. Just don't ask me how to pronounce WYW. :-) pronounce it like wha u as in wha u say? :) What I envision is an apache server running mod_php, opening sockets to a standalone WIW (whatever I want) server (a long-running PHP script) on some other port. Apache/mod_php handles the remote HTTP clients, the WIW server treats the php scripts running from apache as clients. This is what I meant by the incoming load from Apache. I'm betting the do-nothing PHP socket-server will handle VERY heavy load. That code is all thinly-disguised wrappers around the C socket library on your server -- The same library Apache, FTP servers, and so on are all using to handle their load, almost for sure. Whether or not what you need to *DO* with the incoming data and your calculations needed to compose a valid response will be fast enough really depends on what you want your WYW server to *DO*... You might even want to have multiple PHP processes going, just like Apache, if you need to handle really have load. Ok I'm getting the picture. Am I barking up the wrong tree with this whole concern for persistent PHP native variables and code? It seems like the implementation of a standalone PHP server is overkill and I ought to just throw more loadbalanced servers at the application rather than cut the application init time with a solution like this... or at least that is how I'm starting to see it.

[PHP] Persistent PHP web application?
Dear list,
My web application (an online classifieds server) requires a set of
fairly large global arrays which contain vital information that most all
the page scripts rely upon for information such as the category list,
which fields belong to each category, and so on. Additionally, there are
a large number of function definitions (more than 13,000 lines of code
in all just for these global definitions).
These global arrays and functions never change between requests.
However, the PHP engine destroys and recreates them every time. After
having spent some serious time doing benchmarking (using Apache Bench),
I have found that this code takes at least 7ms to parse per request on
my dual Xeon 2.4ghz server (Zend Accelerator in use*). This seriously
cuts into my server's peak capacity, reducing it by more than half.
My question is: is there a way to define a global set of variables and
functions ONCE per Apache process, allowing each incoming hit to run a
handler function that runs within a persistent namespace? OR, is it
possible to create some form of shared variable and function namespace
that each script can tap?
AFAIK, mod_python, mod_perl, Java, etc. all allow you to create a
persistent, long-running application with hooks/handlers for individual
Apache requests. I'm surprised I haven't found a similar solution for
PHP.
In fact, according to my work in the past few days, if an application
has a large set of global functions and variable definitions, mod_python
FAR exceeds the performance of mod_php, even though Python code runs
significantly slower than PHP code (because in mod_python you can put
all these definitions in a module that is loaded only once per Apache
process).
The most promising prospect I've come across is FastCGI, which for Perl
and other languages, allows you to run a while loop that sits and
receives incoming requests (e.g. while(FCGI::accept() = 0) {..}).
However, the PHP/FastCGI modality seems to basically compare to mod_php:
every request still creates and destroys the entire application
(although the PHP interpreter itself does persist).
Essentially I want to go beyond a persistent PHP *interpreter* (mod_php,
PHP/FastCGI) and create a persistent PHP *application*... any
suggestions?
Thanks in advance for any help!
Regards,
J. Whiting
* - Please note that I am using the Zend Accelerator (on Redhat
Enterprise with Apache 1.3) to cache the intermediate compiled PHP code.
My benchmarks (7ms+) are after the dramatic speedup provided by the
accelerator. I wouldn't even bother benchmarking this without the
compiler cache, but it is clear that a compiler cache does not prevent
PHP from still having to run the (ableit precompiled) array and function
definition code itself.

Re: [PHP] Total Server Sessions
$num_sessions = count(glob(session_save_path() . '/sess_*'));
echo There are about {$num_sessions} active sessions.;
It will be fairly active so long as your garbage collection is triggered
fairly often.
it is worth noting that this doesn't work if you are using the recursive
directory structure method to store sessions, or any other session
storage method other than the default (in-memory sessions, database
sessions, etc). and on a shared host, you may be counting the total
number of sessions for all the virtual hosts on the server. also, on a
shared host, it is usually up the sysadmins how PHP stores sessions, so
your mileage may vary.

[PHP] classes and variable scope

$some_global_variable = abcd;

The first echo statement (the one inside the set_global function) prints
abcd, but the second prints nothing. How can I set the value of
$some_global_variable inside the set_global function so that it sticks?

[PHP] bubble sort crashing apache
I've implemented my own bubble sort function that is crashing apache.
Can somebody either help me out with the bubble sort or help me figure
out a way to solve my problem with php's built in sorting functions?
This is my problem. I'm writing my own class for displaying html tables.
Right now, the only thing this class really abstracts is the sorting of
the table rows by any column ascending or descending. My table class
accepts an array of $row objects. Each $row object itself contains an
array of $cell objects. I've included the function I'm using to sort the
rows at the end of the email.
The problem I'm seeing is that after about the 3rd sort on a particular
column, apache crashes. Maybe bubble sort isn't the best sorting
algorithm, since when the user switches from ascending to descending
sort order on the same column or vice versa, I get the worst case
scenario for a bubble sort (the data is in reverse order).
Any ideas? Thanks!!
private function sort() {
$col_name = $this-order_by;
/*
** Get the column number of the column we're
** ordering by.
*/
for ($i = 0; $i count($this-col_names); $i++) {
if (strtoupper($col_name) ==
strtoupper($this-col_names[$i])) {
$col_num = $i;
break;
}
}
/*
** bubble sort
*/
for ($n = 0; $n count($this-contents); $n++) {
$sorted = true;
for ($y = 0; $y count($this-contents) - 1; $y++) {
$cell_arr_this =
$this-contents[$y]-get_cell_arr();
$cell_arr_next = $this-contents[$y +
1]-get_cell_arr();
if
($this-out_of_order($cell_arr_this[$col_num],$cell_arr_next[$col_num]))
{
$tmp_row = $this-contents[$y];
$this-contents[$y] = $this-contents[$y

$sorted = false;
}

Usually is sendmail or compatible and can be configured to relay messages to a SMTP server instead of deliverying them directly. Under Linux/Unix PHP just hands the message to the sendmail program. It would not make much sense to relay messages a SMTP server when sendmail can be more efficient by sending them directly to the SMTP of the recipient users, unless you are trying to send messages from a server that is blacklisted and the world is not accepting messages from it or because of some other blocking reason. Anyway, if you really want to relay messages to a SMTP server under Linux/Unix, the mail function will not do that. Instead you may want to try this class that comes with a wrapper function named smtp_mail().

Robby,
I just enabled log_errors locally. No errors (as I thought).
Since I am hacking a previously written site, the problem seems to arise
most
when accessing his pre-built functions across pages. For instance, he uses
a
'cards.php' to store all display functions -- showleft() -- showcentre() ,
as
well as the connect() function. Since its a persistent connection -- he
opens
the db once, then performs various queries in it. However, since
'cards.php'
has already been called once by a page that might require both showleft()
and
showcentre() -- it barfs and says that it cannot 'redeclare' the
showleft()
function that has already been declared?? That is really some weird --
particularly when it works so well (as expected) locally - and also since
I'm
not 'redeclaring' but calling it for use!
I cannot fathom why the production site would give this error. Perhaps I
need
to do absolute paths for all headers? But it doesn't make sense that a
function cannot be called many times -- declaring it once, yes, but
calling
its use?? If that were the case, then one might as well write it out
longhand
for each use, and forget the concept of 'functions'.
I think I should look at the error logs for the site -- maybe they will
clue
me in where I should look.

Andre

Say the template is:

the example I quoted didn't use include(). Dont use include, use

You're not making senseyou're saying that using preg_replace *in*
the included code doesn't work? That can't be what you mean.
Including a file does *not* include it at the top of the page. It's
included wherever you put the include statement. You can put them
*anywhere*, not just at the top of the page. See the DB::connect()
method in PEAR DB for an example.
http://cvs.php.net/co.php/pear/DB/DB.php?r=1.59
If what you're saying is that the output goes to the browser, you can
use the output buffering functions to catch the output.
http://us3.php.net/manual/en/ref.outcontrol.php
If what you're doing is similar to this:
$text = file_get_contents('templateFile.php');
$text = preg_replace('/something/', 'something else', $text);
eval($text);
Then you *are* changing the text before eval-ing it (you never
answered the many questions about this). If this is what you are
doing, then it sounds like the issue is not in the eval or the
included file, but in the preg_replace. Please give us the exact
preg_replace line that you are using and what it is supposed to do so
we can help with your regex.

[PHP] javascript type cast
Is there any way to do a typecast in javascript? I know you can in 2.0, but that won't work here. I have an input field and I need to add a number to it's value. var + 123 == 'var123' You would think that it would automatically typecast var to an int since it's being added to one, but it just concatenates it instead.

Re: [PHP] javascript type cast
Ok. I write most my web apps in php. I rarely will use js for anything, but I needed it on this rare occasion. I didn't want to have to post to the same php page to get the results to change, so I though a little js would do the job. Being a php list, I thought that a few others would have run into the same issue while doing this. Would it have made it better if I talked a little about the php work that was being done on the page also? All this is doing is making me like php less and less. And what about the newer users to the list? This also makes me not want to answer other peoples questions either. I've also noticed that a lot of answers to peoples questions get flamed on this list also. It's like you think you're better than them and came take them down for whatever reason. Yes, the question was OT and I knew it. Yes, I found the answer via google 5-10 mins later. I had already searched a while before for it. And I'm not going to go and get on a js list for one question I may have once every 3 months. I figured someone here has ran into the same situation before. Especially since type casting is a common thing among most languages (even php). All I have to say is, sorry I asked. I really wasn't worth it. -Josh On Tue, 03 Aug 2004 13:09:19 -0500, Alex Hogan [EMAIL PROTECTED] wrote: I have been on a number of lists over the years, as what ever technology I'm using at the time has demanded.

Globals are off,
Magic_quotes are off
The file is the same
I cant use include with a preg_replace (I replace X with file_get_contents
blah because if I dont then the file thats included wont be included in
place of the replaced variable, it will be included on the top of the page
and not where its supposed to me.)
And using buffer is 8x slower than eval.

And why again are you using *eval* on a file? Why not
include('file.php')? If you're doing parsing on the file contents,
look there for your problem. It's likely you're adding backslashes
somewhere. Look at the contents of the string you're trying to eval
and see if it looks the same as the file you want to run. If not,
that's your problem.
If you're not adding slashes, perhaps magic_quotes_runtime or
magic_quotes_gpc is? (These are php.ini settings)
What vars aren't getting passed in? Globals? Looks like this is OOP,
in which case globals aren't in scope while you're in a function. You
call a function to run the template and the globals are automtically
out of scope. You can do several things here.
1) Use $GLOBALS['varname'] instead of $varname in your eval'd script.
2) If you're using globals for request vars (GET or POST) then you
should switch to the superglobals $_GET and $_POST (or $_REQUEST).
3) global everything in $GLOBALS before you run eval()
foreach ($GLOBALS as $key = $val) {
$$key = $GLOBALS[$key];
}
If none of this works, perhaps safe mode is stopping this? (I'm not
sure if it even can, but it's a possibility.)

and see if it looks the same as the file you want to run. If not,
that's your problem.
If you're not adding slashes, perhaps magic_quotes_runtime or
magic_quotes_gpc is? (These are php.ini settings)
What vars aren't getting passed in? Globals? Looks like this is OOP,
in which case globals aren't in scope while you're in a function. You
call a function to run the template and the globals are automtically
out of scope. You can do several things here.
1) Use $GLOBALS['varname'] instead of $varname in your eval'd script.
2) If you're using globals for request vars (GET or POST) then you
should switch to the superglobals $_GET and $_POST (or $_REQUEST).
3) global everything in $GLOBALS before you run eval()
foreach ($GLOBALS as $key = $val) {
$$key = $GLOBALS[$key];
}
If none of this works, perhaps safe mode is stopping this? (I'm not
sure if it even can, but it's a possibility.)

you say you're getting a parse error. How could anyone possibly help

troubleshoot that parse error unless they had an example of what was

[PHP] Re: [tcphp] alternating highlights
This is very simple actually
?

while($row = mysql_fetch_array($result)){
$field1 = $row['field1'];
$field2 = $row['field2'[;
if($flag){

?

[PHP] multiple checkboxes
Very simple question. When making multiple checkboxes, you put the name the same for a few to group them together form action=process.php method=post input type=checkbox name=checkBoxGroup value=first / input type=checkbox name=checkBoxGruop value=second / /form So they are grouped but then submitting them I only get the last value check. ? print_r($_POST); ? How would I get all the boxes check when grouping them by using the same name for all checkboxes in the name field? -Josh -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] php 4.3.7/5.0
I've noticed that in the last release of php 4.3.7 (or 5.0.0), that
when checking the value of a variable has changed.
ex:
if($var){ /* do something */ }
doesn't work anymore. I've had to change code to
if($var 0)
but the problem is, what if $var was converted to $var = 0 instead
of $var = 0 somewhere throughout the code that I didn't know about?
Is there a way to be sure what's going on here?

Re: [PHP] php 4.3.7/5.0
Well, the actual code is hard to tell. It's grabbed from a db so it
should be an int. But it's also run through some functions. That's why
I'd like a to tell what's going on better.
The variable is always set. Basically
$result = mssql_query($sql);
$row = mssql_fetch_array($result);
$var = $row[0];
So it should be an int. And if it's copied into a function it
shouldn't be changed.
But doing
if($var)
doesn't seem to work after I upgraded versions. Which is making me
think that they changed how that works.
And using is_string() or is_int() is pointless 'cause it doesn't
matter. I just want to know if the value != 0.
The problem is, if 0 gets changed to 0 somewhere throughout. That's
why I've always used if($var) because it's usually not cared what the
type is, but it seems to now.

These values will all *not* do something:
var_dump((bool) 0);
var_dump((bool) array());
var_dump((bool) );
var_dump((bool) 0);
var_dump((bool) null);
var_dump((bool) false);
doesn't work anymore. I've had to change code to
if($var 0)

Re: [PHP] php 4.3.7/5.0
I think I'll just have to typecast everything, that should always work then.

You can typecast values as well, this may be a good way to achieve what
you are looking for:
if ((int)$var != 0) {
// Do Something
}
Also, if you are going to use this variable as an integer later you can
do the following to explicitly convert $var into an integer:
$var = (int)$var;
That should convert 0 into the integer value 0. Also, note the
following:
var_dump(0 == 0); //bool(true)
var_dump(0 === 0);//bool(false)

Re: [PHP] php 4.3.7/5.0
I'm positive that it will always be set, 'cause I set it. It's just
going the comparison.
if($var)
used to work for
if($var != 0) or if($var != 0)
but that doesn't seem to work since I upgrade. So I'm just going to do
if((int)$var)
from now on, 'cause that should always work. I'll typecast everything
that being compared to and int to make sure.

Re: [PHP] php 4.3.7/5.0
That sounds about right. It pretty much described the behavior between
the two versions.

I agree. As I pointed out in my earlier message in this thread, based on
the description that the OP gave (and the fact that he's using
mssql_query()), I think he's getting bitten by the problems introduced by
the fix for bug #25777:
http://bugs.php.net/bug.php?id=25777
Basically PHP used to trim trailing spaces from data being returned via the
mssql and sybase extensions, and the fix for the above bug (in both
extensions) was to stop this trimming. In my case this introduced a new
problem, because bit fields that contain simply '0' in the database come
back with trailing spaces. While this:
$ php -r 'if (0) echo Yes\n;'
produces no output (because 0 == false) this does:
$ php -r 'if (0 ) echo Yes\n;'
because 0 != false.
I have a hunch that if the OP does a print_r() on their $var, it will be a
string that starts with zero and ends with one or more spaces. Casting $var
to int will restore the original behavior, but this is only because (int) 0
=== 0 and 0 == false. So basically the cast to int does fix the OP's
problem but not for the reasons he believes.
Of course, that's a complete guess based off incomplete information. I
could be way off. :)
