[PHP] OOP to run sequential SQL queries?
Dear list, We have a bunch of SQL-queries, they should be executed in a sequential order, with a defensive programming style in mind. We were thinking to implement the solution as Stored Procedures instead of a PHP solution that runs SQL queries, but an article in Coding Horro recommendeds to avoid SP for good reasons: http://www.codinghorror.com/blog/2004/10/who-needs-stored-procedures-anyways.html Now we're going to carry on in PHP, and my experience says that we should write the solution in a procedural-style, instead of OOP. Is there any benefit to use OOP in these situations? Please share your thoughts. Thanks, -behzad
[PHP] Apache to serve RESTful requests using PHP
Dear list, We're a developing a PHP-driven web service with a RESTful API, and we have a dedicated Linux server for that with 6GB of RAM. Since this service will be used by many clients in a concurrent manner, we'll face with a high-load on our web-server. But web-services are different from web pages, for instance they don't include images, or in this case we only serve JSON. I'm wondering what are the recommended configurations for the Apache web-server in these situations? Should we disable keep-avlie? What about other directives? Apache is our bottleneck, and we're trying to optimize it. Should we use nginx instead? Please let me know your suggestions. Thank you, -behzad
Re: [PHP] Apache to serve RESTful requests using PHP
Bastein, Response is unique per request, and not cachable. The app fetches records from MySQL (say, templates), performs a process on them, and returns the generated output as JSON. We were thinking to use Redis to reduce queries against MySQL, but still Apache will remain as our bottleneck.

You're likely to get bigger performance gains from caching frequent data. Keep-alive at maybe 1 second. But would need to know more about the app to be able to suggest more Bastien
Re: [PHP] Apache to serve RESTful requests using PHP
Stuart, thanks for your detailed response. I find it unlikely that Apache is your bottleneck, especially with a service involving MySQL. How have you come to this conclusion? Apache is the entry-point to our service, and I did a benchmark with AB to see how it can handle concurrent requests in a timely fashion. After a number of 50 concurrent requests, the average time per request reached from less than a second to 5 seconds. On the other hand, the MySQL's slow_query_log was clear, with long_query_time = 1. Our MySQL database consists of less than 200 records, distributed in normalized tables, yes, queries are making joins, but the overall performance is OK. As far as keep-alive goes, how frequently will individual clients be accessing the service? There are only a few clients that call the service. These clients are PHP-driven web pages. Each page has its own unique ClickID and a set of other unique parameters per user visit. These pages send these parameters to the service using php-curl, and expect a generated response to be returned. That's why I'm saying each request and response is unique. Whenever a user visits a web-page, there would be a call to the web-service. At the moment, we don't know number of concurrent visits. We're looking for a way to figure that out in Apache. Is there a way to see if the requests are using the previously keep-alived http channel? Because same client will send requests to the service, and I'm curious to know if the Apache will allocate the already-opened channel, or will create a new one? If you are using joins to pull in extra data (i.e. IDs to a name or similar) look at using Memcache for those, but make sure that when they're updated in the DB they're also updated in Memcache. Memcache or Redis, I'm going to add a caching layer between MySQL and PHP, to store the de-normilized data. I'm starting to learn more about nginx + php-fpm, thanks for sharing your positive experience about this. -behzad

Re: [PHP] Re: Joining a team, where no wiki or docs are available
That's like erasing the question from the paper, in order to give it a solution! I was thinking about this problem for a while, and I've ended-up with this approach: #1 Start using the software as an End-User (don't care about the code) to understand the business-value of the software #2 Take a look at the database scheme, try to understand the entities and their relations #3 As you use the software, you'll become more curious about its features and how they've implemented. #4 Start to see how they've implemented common problems, such as: Authentication, CRUD, etc. How the other interesting features are implemented So that's an approach. What do you think? You can't join a team and ask them: How this software is implemented? They'll simply stare at you. Instead, *we need to ask smart questions*. Now where these smart questions come from? We need to understand some of the design prior to ask questions, right? With that basic understanding, we can ask good questions, and will gain benefit from the answers.

Since i'm just a php-programmer, i *thought* of a MySQL database to hold these data, and then use a SOAP-Server to handle the authentication across those applications.

[PHP] Implementation of non-linear business processes in PHP
Dear List, Helllo!!! I'm trying to write a web application for my own ISP, to simplify the processing of orders for Internet Accounts, creating reports of their users, and keeping track of their sales. A brief history: This ISP provides ADSL connections over ordinary telephone lines for home users. The activation of ADSL for these kind of users is a bit complicated, and its business process is not linear. For example, some telephone lines do not support separation of data and voice, because their type is PCM. There are many situations that they can't provide ADSL. The ISP company has many resellers on the country, there are many Administration Groups, etc. With PHP, I'm trying to simplify this process. I guess there are many examples out there, but I want to write the application by myself in PHP. A short list of requirements are: 1) Ability to add/edit Resellers, which in turn, they can have their own Admins, Standard Users (ISP Insiders), and they have different roles. Perhaps one user is allowed to view quotes, the other is allowed to edit invoices, and one user is allowed to finalize the orders. 2) Ability to change the order of different processes. For example, in one situation the payment should occur before the ADSL connection, in the other scenario the payment is not necessary at the first place ( a 30-day trial connection ). Is there any solution to implement non-linear business processes in PHP (where different tasks could be done by different users, with different roles, in different order)?

Re: [PHP] Server-side encryption to prevent form hacking: new idea?
Suppose you have the following array:

which is used to generate the following Select:
*select name=city
option value=TehranTehran/option
option value=IsfahanIsfahan/option
option value=TabrizTabriz/option
/select*
You can check whether the submitted value is valid or not, using the
following code:
*if ($_SERVER['REQUEST_METHOD'] == POST) {
if (!in_array($_POST['city'], $cities) die('Invalid');
}
*
Hope this helps.

Sometimes we can avoid this, especially if we have an image per

Suppose you allow each user to upload a GIF/PNG/JPEG image;
the below code assigns the correct image for every user:
foreach ($users as $user) {
$user['avatar'] = reset(glob('../img/avatars/' . $user['id'] .
'.*'));
}
If you can grant the images are .GIF, then you can reduce the
overhead of searching for images:
foreach ($users as $user) {
$user['avatar'] = '../img/avatars/' . $user['id'] . '.gif';

[PHP] Concatenation vs. Interpolation

Could we consider the 1st Method as a Best Practice, which offers better Performance? I know that the performance here is not very much, but is it considerable in a high-traffic website? Thank you in advanced for sharing your opinions, Behzad
Re: [PHP] Concatenation vs. Interpolation
You're right. There is a low benefit in performance. But I think it's
valuable
in high-traffic websites. Of course, we should consider a lot of thing to
have a better performance, but Concatenation, IMO, is the best practice.
Let me explain:
َActually, the programmers' preference on readability and write-ability
varies.
I think that concatenation provides a more readable syntax, since it
allows us to distinguish variables from plain strings very easily.
Consider the following code:
$str = 'My name is ' . $name . ' and I live in ' . $city;
VS.
$str = My name is $name and I live in $city;
(You may view the above code in an Editor with syntax-highlighting
capability for a better result). However, it is possible to offer
opposite examples.
In addition to the Performance on Speed, Concatenation uses less memory
than Interpolation, as explained in PHP Manual. Take a look at the
following URL:
http://us2.php.net/manual/en/language.types.string.php
Quote:
Note: Parsing variables within strings uses more memory than string
concatenation. When writing a PHP script in which memory usage is a concern,
consider using the concatenation operator (.) rather than variable parsing
Thus, I think that it is better to use Concatenation instead of
Interpolation.
Since it provides Performance, both on Speed and Memory Usage.
There is a benchmark available here:

Code readability is quite important when working with a team on a
project, and if you got for method 1 on things like this:
$str = 'a href='.$url.'';
It gets quite inreadable, having a double qoute next to a single quote.
while this looks much better:
$str = a href='$url';
I just did some benchmarks myself, and you can see that concatenation
is definitly a little bit fast, but it's only 2 seconds on 10 million
loops:
For 10,000,000 loops:
Concatenation single quote:5.62786102295
Concatenation double quote:5.6335657

Of course, I hate Rails-style code-generation frameworks anyway, so I'm kinda glad I never actually built that project. :-) YMMV.

I'm a rather inexperienced developer who's catching on quickly, and looking for a framework to build out a project I've been assigned. I'm more of a read a book and try things out type of learner. My question to those with more experience, what exactly is the difference between CakePHP and Symfony? I'm looking into both of them for a potential framework to make robust and scalable code. They both seem to try to obtain the same goals with their project, however Symfony has text written about it, etc. Anyway, thank you for any insight. - sf -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Pirate PHP books online?
I'm living in a country where people do not afford to buy real books. Most people earn $250~$400 per month. $50 for a book is too damn expensive. In addition, since US has restricted business with us, no body ships books to us. And we don't have Credit Card, since Master Card, Visa, Paypal do not offer services to us. How can we read books in such a country? I would like to know your opinions. Thank you.

Royalties are no secret: Apress publishes its standard contract on the web for prospective authors to see. The basic rate is 10% of the net income received by the publisher. Since heavy discounting is prevalent in the publishing industry, this means the author ends up with less than 5% of the book's cover price. So on a book with a cover price of $40, the author gets less than $2. Based on the fact that this is almost identical to every other publisher (O'Reilly, Sams, etc.), and based on the fact that Richard said he has a lot of experience in this industry, I suspect his estimate was spot on. You're right, though, it's difficult to get any return on your time investment. :-) Chris -- Chris Shiflett http://shiflett.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Migration from MySQL to MS-SQL Server
Hi List, I want to re-implement a PHP-driven package named ATutor (http://atutor.ca) to work with MS-SQL Server. Currently, it works with MySQL. Unfortunately, authors of ATutor have not defined a class for database connectivity. In other words, they call each mysql functions directly in their code. It seems that I must change every line of code to make ATutor work with MS-SQL Server. 1) Is it suffice to replace every mysql_FUNCTION with mssql__FUNCTION in the code? I realized that most of MSSQL functions are very similar to MySQL functions, but their prefixes are different. (I should kindly thank the PHP Development Team for this) 2) I have not worked with MS-SQL Server before. Is there anything else which I should keep in mind? Thank you in advance, Behzad

[PHP] Lowest PHP version to work with MySQL 4.1.x
Hi List, I have noted that some versions of PHP are unable to work with MySQL 4.1.x. 1) Should I upgrade to PHP 5? 2) What is the lowest PHP version which works fine with MySQL 4.1.x? Regards, Behzad P.S. I don't use Improved MySQL extension in PHP. I just need MySQL 4.1.x for multi-byte character support.
