[PHP] Re: Persistent PHP web application?
George Schlossnagle addresses exactly your requirement in his book "Advanced PHP
Programming".
Josh Whiting wrote:
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.

Here's what's wrong with this plan:
#1.
You are exposing the fact that you use MySQL to users. So malicous users
don't need to figure out that you are using MySQL: They can just start
trying all the MySQL things to break into your server.
As a general rule, you do not want users to know what software/version you
are running.
While this does fall into the "security by obscurity" category, which is
generally not "good" there are compelling arguments for making it harder
for the bad guys to figure out what software you are using.
#2.
They won't.
Oh, sorry.
The USERS will *NOT* email your message to the webmaster. Oh, some will.
Most, however, will email your webmaster with oh-so-usefull messages like.
"I was on your website, and I got an error message, and it's broken.
HELP!"
Put the details you need to debug your software in a place where you
webmaster can read them, no matter what the user does to mangle, shorten,
or otherwise ruin the message.
http://php.net/error_log is good for this.
#3.
It's just Bad Form to tell users a bunch of crap they don't understand,
don't care about, and can only be puzzled by. The message the users see
should be more like: "Website down for maintenance. Please try again
later."
The error messages you need to FIX the site are in the Apache log (or your
own logfile) where they belong.
There might be some exceptions to all this -- If you have only one or two
admin people, whom you trust to actually copy &paste the error messages
and send them to you, displaying them on those admin screens is not so
bad. That user is probably your client who already knows what software is
in use (or can find out easily) and isn't likely to sabotage their own
site, and can maybe be trained to do the right thing... OTOH, logging to
a file and giving them a message they understand ("Something broke. Call
Rich and tell him what you were doing.") is probably better anyway.
I greatly appreciate your taking an interest in my question.
I didn't explain all the details since I was trying to keep my message short.
My users are not public. They are a few selected individuals who only have
access via an Apache authentication dialog.

[PHP] Error logging problem
My site is on a virtual host and I'd like to log errors to a file while I'm
debugging. Can't get it to work.
Here is the code at the top of my script:
ini_set("display_errors", "on"); //also tried "Off"
ini_set("error_log", "/AutoSch/error.log");
$ini_array= ini_get_all();
error_reporting(E_ALL ^ E_WARNING ); //On for debuging only
print_r($ini_array);
Printing $ini_array shows my ini_set() statements are working; but, the errors
are not being appended to error.log.
I put a error.log in the folder, assuming the error handler needed one to append
to.
I don't want to turn on error logging for the whole site; just the folder I'm
working on.

[PHP] Re: Code elegance and cleanliness
Not really knowing why you need to provide indexes for the array, since
they are generated automatically if none are provided, I'd use:
$imgBkgrnd = array(
'bkgrnd-default.gif',
'bkgrnd-positive.gif',
'bkgrnd-negative.gif'
);
$imgNeeded = table['field'];
$imgName = $imgBkgrnd[$imgNeeded];
The last two lines are a it doesn't matter.
Note the use of single quotes in the array.
The parser can simply treat the values as text rather than having to
check for variables, etc.

Just a quick question. Does it really matter how long your code is or how
many variables you use? For instance you can enter the following...
$imgBkgrnd = array("1"=> "bkgrnd-default.gif", "2" =>
"bkgrnd-positive.gif", "3" => "bkgrnd-negative.gif");
$imgNeeded = table['field'];
$imgName = $imgBkgrnd[$imgNeeded];
or, you can code the same thing as...
$imgBkgrnd = array("1"=> "bkgrnd-default.gif", "2" =>
"bkgrnd-positive.gif", "3" => "bkgrnd-negative.gif");
$imgName = $imgBkgrnd[$table['field']];
The first example uses one more variable and a longer code block but is
easier to read and debug. The second example uses one less variable and a
shorter code block but is harder to debug later. Should I be striving for
the shortest most compact code utilizing the fewest possible variables. Or,
can I code in a style which is easier to read and debug?

Looks like you have some extra spaces in there that'll mess it up. The '?'

You want

Note that this will only return one match when there could be more,
depending upon your string. If you want all of them, use preg_match_all().

So, when this form is submitted, the page is reloaded and
$page->action("addNewClient") is called which includes the

and added this in my addNewClient.action.php form:
$posted = unserialize(base64_decode($_POST['posted']));
However the $_POST variables only come through after I have clicked submit

Another example of this is PHP's native mail( ) support. (For the uninitiated, CPAN [http://www.cpan.org] is a fantastic collection of standardised Perl extensions with an easy install script that has evolved over many years). Unfortunately the same does not apply for PHP: although it has an impressive array of built-in functions (especially compared to Perl's paltry offering), if a particular feature is not handled natively then you'll probably have to write your own code to implement it. Although there *is* a CPAN equivalent in PHP called PEAR [http://pear.php.net] that boasts a decent number of modules (most of which are still in early development stages), PHP simply hasn't been around long enough attract as much module development as Perl. So in summary: list all the features you need and if PHP supports them all (or if a few are missing and PHP's ease-of-use and other benefits outweigh the cons) then go with PHP, otherwise take another look at Perl. For a list of PHP's features, take a look at the documentation ... it's very user-friendly.

[PHP] Session logic question
I use the $_SESSION buffer extensively on my site without a problem,
except one.
Maybe someone can help me understand the problem.
I have a simple page counter with a test to see if the page has been
counted for the user.
start_session();
*
* [additional code]
*
if($_SESSION['ctr_file']!==$counterFile) //See if
visitor has already been counted for this page
{$num = $num+1;
$_SESSION['ctr_file'] = $counterFile;//set/reset
counter file for next time
Pages that use the counter function all have a start_session(); and a
call to the counter function,
Everything works fine, except when I include another script file that
also uses the $_SESSION buffer.
What appears to be happening is that start_session() on the second
script reinitializes the session buffer and I lose the data from the
first session.
Yet, as I read php manual, it seems to say that start_session is suppose
to simply restore the variables for the page it is on; not start a new
session.
many thanks

Re: [PHP] Another Session Question
Your'e right, that's a typo.
If I put a
echo $_SESSION['counter_file'] .
' testx ' . $counterFile;
Before and after the conditional, $_SESSION['counter_file'] is set after the conditional, as it should be. But, it is gone from the before echo when the function is recalled.
The Session buffer looses the value.
session_start() is called again before returning to the function; but, I thought repeated session_starts() were ignored and thus should not restart the session.
I use the session buffer extensively in other places without any problem.

On a quick glance, three things stand out:
1) You allow underscores in the website domain, but these are not valid
characters for domain names.
2) You allow dashes in the first pattern, but do not escape the dash
character.
3) You have not provided a quantifier to the top-level domain pattern:
[a-zA-Z], so it is only looking for one character fits the class [a-zA-Z].

Ordinarily, the code $ojpp[0][1] = "1" will create an array at $ojpp[0] and set it's second element to be "1". On the first line of your code, however you have *already* assigned the string value "1" to $ojpp[0]. So when PHP sees the code $ojpp[0][1] = "1" it thinks you're trying to use the 'curly braces' syntax for accessing single characters of a string. This syntax is not widely known, but essentially means you can access characters in a string like elements of an array, by using curly braces. For example, will print the third character in $string. For reasons unknown to me, PHP will also let you use square brackets on a string to perform the same action ... eg although this alternate syntax is being phased out. ( For more info see: http://us2.php.net/manual/en/language.types.string.php ). So essentially PHP intereperets $ojpp[0][1] = "1" as being an attempt to assign "1" as the second character to the string already assigned to $ojpp[0]. Which begs the question: why assign "1" to $ojpp in the first line of your code when you seem to want to reaplce it with an array on lines 5 - 8? This kind of coding bug is a by-product of a type-juggling, permissive languge that doesn't require you to pre-declare variables. To fix your code, change the first line of your code to read: $ojpp[0] = array(); Hope that helps, Al -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I can see two problems with your code:
1) The syntax for assigning to $level is wrong.
Rather than:
$level = '$level_' . $_SESSION['user']['level'];
your code should read:
$level = ${'level_' . $_SESSION['user']['level']};
For more information on this syntax, see:
http://us2.php.net/manual/en/language.variables.variable.php
2) You are assigning $level_1 or $level_2 (depending on the value of
$_SESSION['user']['level']) to $level *before* you have assigned $level_1 or
$level_2 any values. There's no point making $level = $level_1 if $level_1
hasn't been defined yet.
Working code would be:
$level_1 = array("PN", "GALUP", "VP", "PUBUP", "STATS", "MCI", "CONLIST",
"CP", "OAFS", "LO");
$level_2 = array("PN", "GALUP", "VP", "PUBUP", "MCI", "CONLIST", "CP",
"OAFS", "LO");
$level = ${'level_' . $_SESSION['user']['level']};

Your sorting function uses strtotime, which doesn't recognise data in the
MM-DD- fomat.
Generally speaking, dates are best stored in the ISO standard format
-MM-DD so that they can be sorted easily with functions like strcmp.
This format is also recognised by strtotime( ). Look in the code below to
learn how to convert your date format to the ISO standard.
If you can't change the date format, you can also modify your sorting
function as following:
// Note this is untested pseudo-code:
function date_file_sort($a, $b)
{
list ($aMonth, $aDay, $aYear) = explode('-', $a);
$aIsoDate = sprintf("%04d-%02d-%02d", $aYear, $aMonth, $aDay);
list ($bMonth, $bDay, $bYear) = explode('-', $b);
$bIsoDate = sprintf("%04d-%02d-%02d", $bYear, $bMonth, $bDay);
return strcmp($aIsoDate, $bIsoDate);
}

In essence what you're trying to do is spider / trawl web pages that do not have consistent HTML formatting with inflexible functions like substr( ) and str_replace( ) that are incapable of adapting to inconsistent search text. You'd be much better off extracting the relevant data from HTML using functions such as preg_match( ) and preg_replace( ) which let you search over text using Perl-style regular expressions (aka regexes).

Hi Mike, There is no surefire way to measure the exact time a user leaves your site. The most accurate way I can think of would be to use a hidden frame on all your pages that refreshes itself every X seconds. When a user has not requested that special tracking page for more than X seconds, you can assume they have 'left' the site. However this solution seems like overkill for most purposes: you'll be wasitng server resources and slowing down your users' experience on your site. In response to your proposed method, most advertising associations (including the US-based Internet Advertising Bureau) and web analytics companies (such as Red Sherrif, Nielsens and Hitwise) define the end of a user session on a website when there is 30 minutes without a further request for a page from the site. And while you may be tempted to track only IP numbers, remember that many users are behind shared IP numbers (e.g. firewalls) which may skew your stats.

[PHP] Re: Get value between 2 strings
Here's what I use:

* $e ending text string [e.g.
*
* @return the extracted text string. [e.g., returns string between

function get_text($text, $s, $e) // Get string out of text
{
$sp = strpos($text, $s, 0) + strlen($s);
$ep = strpos($text, $e, 0);
return substr($text, $sp, $ep - $sp);

could use to easily do this? Please let me know if you have any ideas.

In short: not with PHP. You're going to need a program that can read and render PHP files, and save them as a static image (i.e. gif, jpg, etc). You can run this program (if you find one) using PHP, and then use PHP to resize and manipulate the output image, but PHP cannot natively manipulate PPT files, nor are there any PEAR packages for that purpose.

One change will make your code work: just pass the $var argument by
reference, ie. function sureset (&$var) { ...code... }
I wrote a similar function a while ago, with a little added functionality:
function get_if_set ( &$testVar, $falseValue = NULL)
{
if ( isset( $testVar ) )
{
return $testVar;
}
else
{
return $falseValue;
}
}

Thanks
> for the help.
My last post didn't actually address the error you mentioned though, so I
might as well do that now... :)
>From your example, the warning you received is cause by the add_item( )
method because it's attempting to add 1 to the value of $cart->items['10'].
The only problem is that $cart->items['10'] hasn't been defined yet.
Now PHP is smart enough to realise that if $cart->items['10'] doesn't exist,
it should simply create the key and assign it a blank value (i.e. 0) and
*then* add 1. So any subsequent calls to $cart->add_item("10", 1) won't
generate an warning.
It's also important to note that you only received a warning, not an error,
and that code finished executing properly. You only received the warning
because you had rerror reporting set to strict, which is normally a very
good idea to help keep your code clean and bug free. The reason the code
didn't work as expected was because of the bug addressed in my last post.
To code the add_item( ) method in a way that won't trigger this warning, you
can change it to:
function add_item ($product_id, $quantity = 1)
{
if (!isset($this->items[$product_id]))
{
$this->items[$product_id] = 0;
}
$this->items[$product_id] += $quantity;
}
You can see that the code checks to see if the the key exists, and if it
doesn't sets it to 0, before attempting to add to it's value. This is
essentially replicating what PHP was doing anyway.
Cheers,
Al

The way you are accessing the array is incorrect. The $items array is a
property of the Cart object. Since the Cart object may have many different
array properties, the foreach statement above has to be sepcific about which
array you want to iterate through.
So the correct code would be:
foreach ($cart->items as $product_id => $quantity)
{
echo $product_id . "" . $quantity;
}

[PHP] Idea for new operator
Afternoon all, Is it just me, or would everybody else like to see a case-insensitive string comparison operator introduced into PHP? It is a type of comparison that I use a lot, and having to strtolower() everything before comparison can impact code readability, not to mention the angst, pain and trauma of having to repeatedly type 'strtolower()'. Assuming this new operator is something like '=*', the following two lines of code would be functionally identical. if (strtolower($a) == strtolower($b)) echo "The same!"; if ($a =* $b) echo "The same!"; Of course creating a new operator is only justified if the vast majority of PHP users do these comparisons as much as I do, and are as averse to work as I am ... :).

My question seems fundamental. I want to set a variable in one function in a class and then want to use the value in a second function. However, the functions are called a html page with two passes. Submit reloads the page and an if(...) calls the second function in the class. If I declare on the first run: $get_data = new edit_tag_file(); $edit_args= $get_data-> edit_prep(); The on the second pass, I'm stuck. I can't declare a new instance of "edit_tag_data". And, it appears the object is gone after I leave the page. Will the class structure do this for me or must I save the values in $GLOBAL or something?
