<?php
function processUserInput($a, $b)
{
echo divide($a,$b);
}
function divide($c, $d)
{
print_r(debug_backtrace());
}
echo processUserInput(4,0);
?>


This will output the following one

Really? Then again, how does one measure success with SEO? Do you have to be #1 in search results for ALL the keywords you want? But that sounds impossible! How then do you measure if your campaign is successful?

In a nutshell: metrics. Sure, being number one in the rankings rocks, but metrics gives you a realistic peek at more important figures and numbers to let you know whether or not you are successful in your SEO endeavors. Are you ready to wallow in other numbers? Then read on.

Traffic – Though traffic is one way to check on the success of your endeavors, it is not the only way. Not only should you check how much traffic you have gained, also you must check the quality of these visitors. Do they just enter and leave? Do they explore the site? Knowing the quality of the visitors can give you an over-all insight how others see your site.

Keywords – “What?! But keywords aren’t numbers!” What you should take note is the way your keywords are performing. You should take note of the keywords that are directing traffic in your site. Are these the keywords you intended to use? Or are other keywords scoring more? Depending on the result, you can adjust your future keyword choices as you see fit.

Conversion Rate – This is the true test of an SEO campaign’s success. See how many people filled up the form you offer, or signed up for your newsletter, the results from this gives you the most concrete proof that SEO is working for you.

Free web analytics tools are available in the Internet. The things I have outlined above are just some of the basic metric information that you can glean from web analytics tools. With these tools, you can generate reports where you could check for improvement. Once you have done the optimization correctly, it won’t be long before you can really say that you’re SEO is successful. Only this time, you have numbers to back you up.

The Zend Framework is a fairly standard, (optionally) MVC PHP application framework. It comes with all the usual functionality; request routing, database access, templates (through view files) etc. It also comes with a lot of extra functionality that you might find useful in your application, including some of the best web services libraries available, especially when working with Google’s APIs.

But here’s the kicker: it works entirely standalone. The classes and their methods can, generally, be used statically in any context, or at least independently of the framework. You can use the Zend Framework’s libraries to manipulate dates and times, work with RSS feeds, interact with Google’s Gdata APIs, even generate PDF files (although the functionality isn’t as mature as FPDF).

Fred Wu recently blogged about using Zend Framework with CodeIgniter. It’s a fantastic way to make use of the efforts of all ZF contributors, as well as speed up development significantly. Chances are, if there’s something you’re trying to do in your web application, the Zend Framework can help.

So check it out. It might just make your day.

1. Inform all users of that repository right after any commit
2. If some one locks a file, inform the admin after a successful unlock
3. Keeping track of commits made by any user
4. Do anything after the following event occurs

Start Commit
Pre Commit
Post Commit
Pre Lock
Post Lock
Pre Unlock
Post Unlock
Pre Revision Property Change
Post Revision Property Change


So how to do it? open the hooks folder under your repository folder and find there are files identical to these events. So if you want to do something, for example, after any commit then open post-commit.tmpl file and write code inside it. Write code in python, php, perl, bash or whatever and make that file executable using “chmod” and you are done. Subversion server will take care of the rest.

1. if the year modulo 400 is 0 , its a leap year
2. else if the year modulo 100 is 0, then its not a leap year
3. else if the year modulo 4 is 0, its a leap year
4. else its not leap year

In plain JS, it will look something like the following one


function checkleapyear(year)
{
year = parseInt(year);

if(year%4 == 0)
{
if(year%100 != 0)
{
return true;
}
else
{
if(year%400 == 0)
return true;
else
return false;
}
}
return false;
}


I have seen this in numbers of web sites who are dealing with dates. But why bother when you can do it in the “Javascript way” - yes, take advantage of this fantastic language - heh heh. The following piece of code will do it for you


var dt = new Date(year+"/02/29");
if ("1"==dt.getMonth()) alert("leap year");
else alert("not leap year");


While others, they bait them. Linkbait them, that is.

Don’t be put off by the name. Though it sounds nasty, Linkbaiting is a kind of a misnomer. In a sense, you “bait” people with something that they would want to link to. The result: you get to reel-in more traffic and an increase in popularity. But of course, just like in real fishing, you can’t catch fish with rubber as bait. The bait must be something that the people would want. So what can you use as linkbait?

It’s A Scoop! – No, you don’t need to shout “Extra! Extra! Read All About It!” with this kind of bait. If you have breaking news, share it! Couple it with an in-depth commentary and watch as the school of users flock your site. The tip: pick your own fishing spot. Be the first to cover news on a specific niche and avoid being too broad. It also helps to check if other bloggers have covered the topic in the past.

Hear, Hear! Shame, Shame! – One of the best ways to get attention: be different. When they say ‘yes’ to a topic, say ‘no’ instead. With luck, this can spark a lively debate and those who think so can link to you. Be careful though. Make sure that when you take a side, you defend it with facts; otherwise people will just dump you like the trash you put in your site. The tip: research, research, and more research.

Laughter is Still the Best Medicine – Funny pictures, hilarious posts, tickling stories, these things easily catch juicy links. People love them for that moment of amusement everyone needs. Apart from being great linkbait, this has a lot of potential for social bookmarking sites such as StumbleUpon or Digg.

These are just a few of the many ways to bait links. Once you get the hang of it, get ready for the steady increase in traffic and, hopefully, a great catch of links. Happy Fishing!

If Chicago isn’t an option for you, try PHP Quebec, php london or the DC PHP Conference.

Given an arbitrary (but valid) HTML file, retrieve all the links that would be displayed as hyper links and display them sequentially, having removed any duplicates. You may use any built in function, the phpinfo() of the server used for testing will be attached. You just need to retrieve the links, you don’t need to worry about them being relative or absolute.

Very straightforward, no? The trick is doing it well, and Paul intends to thoroughly test your entry.

So, why should you enter? First, it gives you a chance to test your PHP skills in a new environment - experimentation. You not only have to build the script, you have to build it well, and quality isn’t always a criteria in your day-to-day development. You might also learn something new, especially if you don’t often work with the string functions or regular expressions.

Head over to his post on the c7y boards and give it a go.

By the way, you might find this tutorial on link scraping useful.

Is it time to start preparing our Delphi for PHP eulogy?

Anyone remember Delphi for PHP, the much discussed RAD IDE for PHP? Its RAD features (think visual web page design, only not Frontpage style but VB style) were pretty cool. The idea of a common interface to open source components was also pretty awesome. And the product itself was decent, despite being somewhat buggy - hey, it was a version 1 release, can you blame them?

I had the pleasure of getting a pre-release copy for review purposes and found that, barring a problem with the licensing system, it was really quite good.

Of course, nobody I’d talked to about it managed to get it working for anything. I couldn’t achieve much with it either. It took me presenting at a Delphi User Group about the product and trying to work it out with a room full of Delphi developers before I managed to even fetch records from a database.

So maybe it wasn’t the next killer product for PHP developers. But it was the next killer product for Delphi developers. They sure seemed to understand it, and my crash course in PHP syntax was enough for them to understand its inner workings - after all, it was exactly what they’d been doing for years with pure Delphi, only with a different language underneath.

Some suggested it would create a massive dilution in quality of PHP developers, as developers working with Delphi for PHP would not really understand PHP application development. But where has this fantastic product, doomsayer predictions and all, gone?

Since its initial release, the product has been updated but in general is still in its buggy version 1 state. There is some private beta testing of the next major release, but we haven’t yet heard anything and the product has long lost its momentum in the community.

Where is the product headed now? If you are reading this, chances are you hadn’t heard of D4PHP before. It never really gained much traction, it lost what little it had, and now it’s sort of hanging in limbo. CodeGear will have to really impress us with version 2 if they want this project to make it.
