Web Design Company

As much as the web designing process is itself a complicated one, choosing the right web design company is also very challenging. You need to take a few things into account before you can start off with the search for the right Web Design Company.

In choosing the web Design Company the first step is to look for the most reputable companies through sources and authentic information. 

It is recommended to inquire in your network of contacts related to this business that have had the exposure and experience with a web developer which was worth repeating when in need. A personal experience matters a lot. For the search of potential web designer companies, even the internet, and the news papers can shortlist the worthy ones.

CakePHP – Import a Controller using App::import()

October 8, 2011 Leave a comment

Hi All,

Have you ever use controller inside another controller(two controllers) in CakePHP ? If you are looking for the same thing, you are at the right place. I was working with CakePHP and i need to use a member info method of member controller in order controller(two controller in CakePHP). Instead of writing a code again in order controller, i searched for using controller inside controller. This can be easily done using App::import method of CakePHP.

App::import('Controller', 'Members');
class OrdersController extends AppController {
    var $Members;
    function beforeFilter() {
        $this->Members =& new MembersController; // Loads the class
        $this->Members->constructClasses(); // Loads the model associations, components, etc. of the Members controller
    }
    function index() {
        $this->Members->memberinfo();
    }
}

 


										

Using regular expressions to extract content – php extract texts from html content

October 3, 2011 Leave a comment

PHP provides a number of really neat regular expression functions. You can find the list of the regex function at the PHP site.

But the one that I’ve had most fun with is the preg_match_all() function which I’ve been using to do content extraction from an HTML page.

I’m not going to explain what Regular Expression (regex) is in this post. There are whole books on just this one topic along; I would be crazy to think I can explain it all in just a few paragraphs. But in order for you to understand how to use the regex functions you need to have a basic understanding of regular expressions.

If you think back to your childhood days, you would remember a toy that you can match holes with shapes with the corresponding blocks – like the picture here. Well, regular expressions is very much like that toy, but instead you have define your own ’shape’ (or pattern as it’s known) and apply your content to it. Any text that matches the pattern will ‘fall’ through it.

Let’s say you have a block of text like below and you want to extract out the all links from, you can use preg_match_all to do just that.

$content = "He's goin' everywhere,
<a href=\"http://www.bjmckay.com\">B.J. McKay</a> and his
best friend Bear. Rollin' down to
<a href=\"http://www.dallas.net\">Dallas</a>, who's providin'
my palace, off to New Orleans or who knows where."

The pattern you want to look for would be the link anchor pattern, like 
<a href=”(something)”>(something)</a>. The actual regular expression might look something like
Once you have your pattern you apply the $content and $regex_pattern to preg_match_all() like this

$regex_pattern = "/<a href=\"(.*)\">(.*)<\/a>/";

Once you have your pattern you apply the $content and $regex_pattern to preg_match_all() like this
preg_match_all($regex_pattern,$content,$matches);
print_r($matches);

preg_match_all will store all the matches into the array $matches, so if you output the array, 
you’ll see something like this.
---------
Array
(
    [0] => Array
        (
            [0] => <a href="http://www.bjmckay.com">B.J. McKay</a>
            [1] => <a href="http://www.dallas.net">Dallas</a>
        )

    [1] => Array
        (
            [0] => http://www.bjmckay.com
            [1] => http://www.dallas.net
        )

    [2] => Array
        (
            [0] => B.J. McKay
            [1] => Dallas
        )
)
---------

From this array, $matches, you should be able to loop through and get the information you need.

I hope this has been useful to you. I know it doesn’t cover all the things this function can do, but for first-timers, it should be a simple look at a very powerful PHP function.

Incidently, PHP also provides the function preg_match(). The difference is preg_match() only matches a single instance of the pattern, whereas preg_match_all() tries to find all matching instances within the content.

Optimizing PHP Through Habits

September 23, 2011 Leave a comment

What has been a long interest of mine in writing simple, maintainable and secure (a.k.a. Good[tm]) code, has forked off the offspring of optimization.

There are nummerous discussions in the blogosphere about whether to use echo versus print, iffor() is faster than while(), etc. and though the gains are usually very small, I desided to add my thoughts to the debate.

I found an article on optimization through coding habits in Ilia Alshanetsky’s zend performance slides and decided to test some of the claims. My test machine is my MacBook Pro 1.83GHz w. 2GB RAM, MacOS X 10.4.9, Apache 1.3 and PHP 5.2 (with Xdebug 2.0). I also have lots of applications running.

  • Peter Bowyer claims that require_once() is 3-4 times slower than require(). Ilia also says they are bad. My testing reveals the exact opposite with an empty include file. Callingrequire_once() 10000 times in a for() loop with an empty file is 4x faster.
  • Ilia advises against using magic functions like __autoload() and __get(), but the advantage of __autoload() in particular is obvious in any large project and is used by many phpframeworks. My primitive testing, however, shows inverse results. With a simply autoload requiring a class and 10000 loops of new Foo() versus require_once('foo.php'); new Foo() shows that __autoload() is ~3.7 times faster. I saw no difference between real methods and __get(), although the logic inside __get() will add some overhead.
  • If a class method can be static, declare it static. Speed improvement is by a factor of 4. I get a 50% speed increase (614ms vs. 414ms with 100000 iterations).
  • Avoid function calls within for() loop control blocks. In for( $i=0; $i<count($x); $i++ )the count($x) is called at every iteration.
  • Always, always quote array keys. $row['id'] is way faster than $row[id]. Ilia says 700%, I say about 200%.
  • Avoid regex if possible. Use ctype_digit($foo); rather than preg_match("![0-9]+!", $foo);.
  • Get rid of ‘harmless’ error messages – they take time to generate and output. The error supression operator @ is slow, so avoid when possible. With error_reporting set to E_ALL | E_STRICT on my machine, doing echo $rows[id] 10000 times instead of echo $rows['id]takes 38 times longer.

     

    UPDATE: To summarize, this slow code runs in 500ms (although this time will vary a great deal depending on your error_reporting level):

     

     

     

     

    $rows = array_fill(0, 10000, array('id'=>0));
    require_once('foo.php');
    for( $i=0; $i < count($rows); $i++) {
        foo::notdeclaredstatic();
    
        $rows[$i][id] = 0;
    }
    
    
    
    
    By using the techniques above, it can be made to complete in 68ms:
    
    $rows = array_fill(0, 10000, array('id'=>0));
    function __autoload($classname) { require_once( 'foo.php'); }
    $size = count($rows);
    for( $i=0; $i < $size; $i++) {
        foo::declaredstatic();
    
        $rows[$i]['id'] = 0;
    }
    
    
    10000 iterations is a lot for one request to a page. Using the techniques, the code became roughly 7 times faster.
    
    I am not out to prove Ilia wrong - he knows PHP better than most - and 
    for all I know, they could have optimized those very functions in PHP 5.2. I am, however, 
    interested in seeing what can be done to optimize PHP performance simply by doing things differently,
    by tweaking one's coding style. It would appear that there are improvements, albeit small, to achieve 
    from minimal effort. Plus I was surprised by the discrepancies I found compared to Ilia's recommendations.
