Hi folks,
we have working on a PHP router project for a while, now we have a final
stable release for this.
Roller - high performance router for PHP5.3+
https://github.com/c9s/Roller
And we wrote an extension for dispatching routes, by using this extension,
the dispatch performance is faster 1607% than original PHP version.
(extension is optional).
RESTful support, you can easily define RESTful paths for records.
Features:
- Highly customizable
- Flexible
- APC cache support.
- File cache support.
- Built-in *RESTful* route generator, resource handler.
- Customizable RESTful route generator, resource handler.
- Simple, Useful route path syntax. (rails-style)
- High performance (through PHP extension, can dispatch *1607%* faster
than pure php version)
- High unit test coverage, coverage > *88%*.

Hi all!
I'm interested in creating a custom PHP extension. I have found
several so called tutorials,
but the code examples they contain do not work for me.
Let's stick to this site:
http://devzone.zend.com/303/extension-writing-part-i-introduction-to-php-and-zend/
Basing on it I have following sources:
######################### config.m4:
PHP_ARG_ENABLE(hello2,whether to enable hello2 support,
[ --enable-hello2 Enable hello2 support])
if test "$PHP_HELLO2" = "yes"; then
AC_DEFINE(HAVE_HELLO2,1,[Whether you want hello2 support])
PHP_NEW_EXTENSION(hello2, php_hello2.c, $ext_shared)
fi
#########################
######################### php_hello2.h:
#ifndef PHP_HELLO2_H
#define PHP_HELLO2_H 1
#define PHP_HELLO_WORLD_VERSION "1.0"
#define PHP_HELLO_WORLD_EXTNAME "hello2"
PHP_FUNCTION(hello_world);
extern zend_module_entry hello2_module_entry;
#define phpext_hello2_ptr &hello2_module_entry
#endif
#########################
######################### php_hello2.c:
#ifdef HAVE_CONFIG_H

STANDARD_MODULE_PROPERTIES
};
#ifdef COMPILE_DL_HELLO2
ZEND_GET_MODULE(hello2)
#endif
PHP_FUNCTION(hello_world)
{
RETURN_STRING("Hello World", 1);
}
#########################
The code compiles well with these commands:
$ ./configure --enable-hello2
$ make -j5
# make install
But after I execute the command:
$ php5 -d"extension=hello2.so" -v
I get the following output.
PHP Warning: PHP Startup: Invalid library (maybe not a PHP library)
'hello2.so' in Unknown on line 0
What I am missing here? Can someone help me?
Thanks in advance.

Have you tried google?
I found this comment on the PHP sites[1], and it says that the module
didn't work when copied into the apache directory, but make install
worked fine for him

Yes, you are right. But that was not the case.
Actually, the problem was that I had two PHP packages installed. $PATH
modification worked fine for me.

Good stuff, but the idea that you need an official test person or a test team
to produce solid code that minimises runtime errors is, in my opinion,
completely the wrong attitude. I've been in similar situations several times
and have found that the key is not to try and solve the problem in one big
push. The key to solving the problem of a large codebase with minimal testing
is simply to start somewhere.
Put in the infrastructure for unit testing, then make writing tests a part of
your standard development process. Over time you will find that you are unit
testing the majority of the code. Yes, that will make things take longer, but
you can also be confident that when you fix a bug it stays fixed, because you
know there's a unit test that verifies that the bug has not returned.
In my experience and opinion, limited resources is a big reason to implement
some level of unit testing as soon as humanly possible, not a reason why you
can't. Once you have the unit testing infrastructure in place, make running the
tests the first step in your deployment process. You mention you now use a
version control system, consider adding a hook to require that the unit tests
pass before allowing code to be committed. Alternatively implement a CI
environment which publicly ridicules anyone who checks in code which breaks the
unit tests - it's amazing how much of a motivator this can be, even in a small
team of seasoned professionals.

Not a secret. Not even close to being a secret. I'm no stranger to sites with
the sort of traffic you have, and then some, and I'm fully aware that it
presents a unique set of challenges, but there are simple steps you can take to
make life easier.
Most of the specific issues you mention (DB connections, memcache weirdness,
concurrency problems, and crawler activity) are the result of poor architecture
and/or flawed server configuration. Where the architecture is poor I'd
recommend you design a new architecture and find a way that you can start
moving towards it, piece by piece, without having too much impact on your
day-to-day activities. This is not always easy but I've done it several times
and know it can be done in most situations.
There will always be issues that crop up that you couldn't possibly have known
would happen, but you can load test your app to see what happens at levels of
traffic an order of magnitude above that which you expect. One of my current
clients has a test tool that can generate traffic levels that hit the limit of
EC2 network throughput specifically to see what would happen if they had a
sudden and dramatic increase in usage. Knowing the application can cope at 10x
the expected level of traffic is the only way you can be sure that it can cope
with 1x the expected traffic without breaking a sweat.
There will always be situations that you don't foresee, and conditions that are
difficult to test, but saying that you "can't possibly test" for them is simply
wrong.

You obviously didn't look closely enough. NewRelic is a PHP extension which
hooks in to errors (and many other things) and provides detailed information
for everything that happens while your application is running. Do yourself a
favour and try it.
As an example I recently diagnosed a snowball performance problem with a
ColdFusion application by simply installing NewRelic and waiting for the next
time the server came crashing down. Without the insights that tool gave me it
would have taken me many times longer to identify and fix the root cause.

This wreaks of architectural problems. I understand that it's a codebase that
you've inherited and that you're doing your best with it, but what you're
describing are not features of a well-designed, scalable web application. The
idea that MySQL is best used to pull large datasets rather than just exactly
what you need makes my skin crawl. You may want to consider having an offline
process populate Memcache, or look at your DB schema to see if there's a better
way to store the data with a view to optimising access to it.
Oh, and assumptions are the mother of all screw ups. Your logs would be far
more useful if the code caught and properly dealt with problems as they
occurred. Yes, there will be a slight (and I mean very slight) performance hit
for catching exceptions and checking for error conditions, but do you really
believe that most of the large, complex applications out there are not doing
these things? Solid code is far more important than fast code. Servers are
cheap, your time is not. Do the maths!

Granted, in the "real world" you cut corners, but these are now accepted
techniques and should no longer feel wrong. For example, fully normalised
databases are painful in a web context, but the idea of de-normalising the
schema and duplicating data to optimise for access would make anyone who
prefers the "right" way feel dirty. But sometimes it's necessary.
Not doing things the academic way should not make you feel dirty. If it does
I'd suggest you look at specifically what it is about what you're doing that
makes you feel that way, because if what you're doing is backed up by valid
reasons it should not feel dirty.

I still maintain that using NewRelic would be far more efficient and
controllable, but you can certainly roll your own solution. You may also want
to check out tools like Scribe and Splunk to assist with managing and examining
your log files.

You don't need a dedicated tester, and even if you did have one that doesn't
mean that you don't need to test it yourselves. I rarely find myself on the
same side as an employer [unless it's me :)] but yours is spot on, firstly
because if you're happy to compromise on a developer to get a tester then you
didn't really need another developer, but primarily because you should be
testing it yourselves. If you think a dedicated tester will absolve you of your
responsibility to test your own stuff then you have a lot more to learn.
Tools that enable you to automate a lot of what a dedicated tester would do are
legion. Unit tests, CI systems, Selenium, and others will propel your
organisation on the way to building solid software that doesn't fill your logs
up with repeated messages that arise simply because the developer didn't test a
variety of inputs for a given function, both valid and invalid.
I hope I haven't come across as too preachy or rude in these two emails, but
I've heard the arguments you're making many times and they just don't hold
water for me. You may have been doing this for 15+ years, but have you done it
at this scale before? Have you done it in a small company that has the proper
processes and tools in place?
I hope my comments prove useful, and my offer to discuss this off-list stands.

This is a bit related to PHP but mostly mySQL (is there a similar list
for this stuff? Let me know please)
In my mySQL query editor, I am trying to return a value of 0 when
there is no related rows from this query:
(select if(count(ip.payment_amount) IS NOT NULL,
count(ip.payment_amount) , 0) FROM tl_trans_pmt_items ip WHERE
t.transaction_id = ip.inv_id GROUP BY ip.inv_id) as d,
regardless of the combination I use, invalid relationships come back
as NULL - need to return 0 so I can use it in a math formula.
Probably simple - maybe ;-)
Thanks,
Don

While Daniel is right, you can use COALESCE for this. eg. select
COALESCE(count(ip.payment_amount), 0)

What's wrong with checking the number of rows returned in PHP? If the
number of rows is 0, you have no results. If the number is 1, then use
the SQL results value.

Hello,
I am very new to PHP coding. I am trying to achieve a task via PHP,
regarding which I have been googling around for a few days and now come up
with emtpy hands!
Ok, what I need to write is a "website preview script". That is I need to
display a website hosted on serverA and pointing elsewhere, from ServerA (
via curl possibly ).
For example: I have configured techsware.in and google.com on ServerA ( of
course google.com pointing to their IP ). I need to display the contents of
google.com "on my server" , if I call http://techsware.in/google.php which
has some curl coding in it! Note, what I have is the domain name (
google.com ) and the IP on which it is hosted on serverA to achieve this.
Any way to achieve this?
I can achieve this if I put <my IP> google.com in /etc/hosts file ( its
Linux ). But I need to run this script for normal users as well, which
won't have super user privileges and thus unable to edit /etc/hosts file.
So I want to specify somewhere in the PHP script that, google.com points to
<my IP>. I can do this with this little script.
# cat curl.php
<?php
$curl = curl_init();
curl_setopt ($curl, CURLOPT_URL, "http://mytest.com";);
curl_exec ($curl);
curl_close ($curl);
?>
Hope someone from this forum will come back a solution [image: :)]
PS: web server is apache and php version is 5.2
Thank you,

Why can't you use an iframe, or are you trying to offer this other
websites content as if it were on your own site? If so, I would first
check to see if you're actually allowed to do that, as that will bring
up quite a few copyright issues otherwise, which can be very expensive.

No..what I am trying to write a "website preview" plugin attached to a
control panel.. :)
since I am a newbie, I don't know how to achieve this without modifying
hosts file ( I am basically a linux sys admin ) :)
@Martin - I will check it. Since I am a beginner ( of course, just started
to learn PHP today ) I need to start from scratch. If yo could provide some
sample code, it will be great :)
thanks for your input guys..

Hi, Nibin
I wonder what you'd call a <website preview> ...
Do you mean a screenshot or the HTML-response from the server, specially
prepared (sounds like you want to create a proxy ;))?

It does sound more like a proxy than a preview script.
What about using something like this:
http://uk3.php.net/manual/en/function.imagegrabscreen.php
I've never used it, but on first appearances it looks like it should
produce the preview you require.

Hi, Ashley
The question is what this function does ;)
I think it really takes a screenshot of the server - whatever is shown
there right now. But how to get a browser running there in full-screen?
I came around that post for a couple of weeks ago and thought it could be
useful for someone here:

HI all,
But what my requirement here is, I need to display the website configured
on our server. No matter where the domain actually points to :)
Perhaps it can call a proxy....here is the actual intention of creating
this script.
Suppose X created a new website on serverA, but the domain actually
pointing to ServerB. So to test his new website on ServerA, he either has
to edit "hosts" file or use serverA/~user. I don't want him not to use
either method. I would like to provide him a PHP feature on my control
panel says "site preview" through which he can view his website on serverA.
Its just like a website preview option in plesk control panel :)
