function f1(){
if(document.getElementById("d1").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='block';
  document.getElementById("d3").style.display='none';
  document.getElementById("d4").style.display='none';
  document.getElementById("d5").style.display='none';
} else if(document.getElementById("d2").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='none';
  document.getElementById("d3").style.display='block';
  document.getElementById("d4").style.display='none';
  document.getElementById("d5").style.display='none';
} else if(document.getElementById("d3").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='none';
  document.getElementById("d3").style.display='none';

  document.getElementById("d5").style.display='none';
  }
}
window.onload=function(){
setInterval("f1()", 3000)
}
  
  
  
  
  

Above code can be divided into 2 parts. that is javascript and html.

function f1(){
if(document.getElementById("d1").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='block';
  document.getElementById("d3").style.display='none';
  document.getElementById("d4").style.display='none';
  document.getElementById("d5").style.display='none';
} else if(document.getElementById("d2").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='none';
  document.getElementById("d3").style.display='block';
  document.getElementById("d4").style.display='none';
  document.getElementById("d5").style.display='none';
} else if(document.getElementById("d3").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='none';
  document.getElementById("d3").style.display='none';
  document.getElementById("d4").style.display='block';
  document.getElementById("d5").style.display='none';
} else if(document.getElementById("d4").style.display=='block'){
  document.getElementById("d1").style.display='none';
  document.getElementById("d2").style.display='none';
  document.getElementById("d3").style.display='none';
  document.getElementById("d4").style.display='none';
  document.getElementById("d5").style.display='block';
} else if(document.getElementById("d5").style.display=='block'){
  document.getElementById("d1").style.display='block';
  document.getElementById("d2").style.display='none';
  document.getElementById("d3").style.display='none';
  document.getElementById("d4").style.display='none';
  document.getElementById("d5").style.display='none';
  }
}
window.onload=function(){
setInterval("f1()", 3000)
}

The above part is the java script. It has to be inserted the head tag of the HTML Page.

The above code is to be included in the Body of the HTML page.
In the above script we create 5 div tags which contains images. Only one of the div is set to visible and remaining are hidden using the

style="display:block"

and

style="display:none"

.

In the javascript we call the f1() function for every 3 seconds using

window.onload=function(){
setInterval("f1()", 3000)
}

This part of the code loads the function on page load. And in the f1 function we check and swap the images.

                    So, this is the second post! 

                   First Post

                    This is the first post, in this simple little XML example. 

You can see, there are 3 post tags under the global recentposts tag. Each of them contains tags which contain information on the title, author, date, time and content of the post. A simple structure. We begin writing the PHP to parse the information in this XML file and display it in regular HTML.

// URL of the XML feed.

$feed = 'example.xml';

// How many items do we want to display?

$display = 3;

// Check our XML file exists

if(!file_exists($feed)) {
  die('The XML file could not be found!');
}

We need to tell the script where the XML is located. If it’s in the same directory as our script, a simple filename will do. If it’s hosted externally, the full URL will be needed (parsing external XML files will not work if allow_url_fopen is not enabled on your server).

Secondly, the maximum number of items we want to display from our XML file? In this example, I’ve gone for 3, which is all my XML file contains.

Now, we should check to see if the XML file actually exists, and if not, stop the scripts.

// First, open the XML file.

$xml = simplexml_load_file($feed);

// Set the counter for counting how many items we've displayed.

$counter = 0;

We need to use the simplexml_load_file function, and place it into a variable, in this example $xml and we initialise a new variable and set it to 0.

// Start the loop to display each item.

foreach($xml->post as $post) {

  echo '
' . $post->title . '

  Written by ' . $post->author . ' on ' . $post->date . ' at ' . $post->time . '

 ' . $post->content . ' 

';

  // Increase the counter by one.

  $counter++;

  // Check to display all the items we want to.

  if($counter == $display) {

    // Yes. End the loop.

    break;

  }

  // No. Continue.

}
 foreach($xml->post as $post)

This initialises a foreach loop. Everything inside this loop while be executed for every post item in the XML file. Which this line is doing, is taking all the information found under post in the feed, and assigning it to the $post variable. This information will then be able to accessed using $post->title, $post->author, etc. If there is more than one item in the feed (which in this case, there is: 3 posts), the information will be put into arrays. for example, displaying only the title of the most recent post would be done using $post->title[0]. However, in this example, we neednot concern ourselves with arrays, since the foreach loop will automatically display it all for us.

echo '
' . $post->title . '

  Written by ' . $post->author . ' on ' . $post->date . ' at ' . $post->time . '

 ' . $post->content . ' 

';

We are simply displaying the title of the post in a h1 tag, displaying the author, date and time of the post as italics, and then displaying the main content of the post.

// Increase the counter by one.

  $counter++;

After every iteration of the loop, the contents of the $counter variable we initialised earlier will be incremented by one. This is so the script know how many posts we have so far displayed in total.

// Check to display all the items we want to.

  if($counter == $display) {

    // Yes. End the loop.

    break;

  }

  // No. Continue.

}

The script will check if $counter is equal to $display (have we displayed the maximum amount of posts we want to display?), and if this is indeed the case, break out of the foreach loop, thus ending the script. If not, nothing happens, and the loop begins once again.

So, putting all that together, this final script will look something like this:

post as $post) {

  echo '
' . $post->title . '

  Written by ' . $post->author . ' on ' . $post->date . ' at ' . $post->time . '

 ' . $post->content . ' 

';

  // Increase the counter by one.

  $counter++;

  // Check to display all the items we want to.

  if($counter == $display) {

    // Yes. End the loop.

    break;

  }

  // No. Continue.

}

Pixel2Life’s Tutorial Index
Pixel2Life is a tutorial index where loggers can submit their tutorials and articles. The result of hundreds of people doing this is a very large library of specialized’ links. For example, at the time of writing this, the front page contains tutorials about Twitter, Code Igniter, Graveyards and Converting Excel to CSV with PHP. There are also numerous tutorials and articles on PHP frameworks (Code Igniter, Cake PHP etc) that aren’t on the framework’s web site. Be aware that there are excellent tutorials back 6 or 7 pages, so have a dig around for them.

NetTut’s PHP Tutorials
Nettuts is well known for it’s high quality tutorials. They have recently done a 3 part series on making your own PHP framework something you don’t see on an everyday blog. Although there aren’t many PHP tutorials now, new authors are writing more tutorials on them. Often the tutorials are not only PHP, a recent one showed how to make a twitter clone in PHP which used mootools for the AJAX and effects. Lately the editor, Jeff Way, has been doing some screen casts.

PHP.net Quickref
Sorry, I had to put it in. If you don’t know what a certain function does, do a quick search on the quickref page and find it in seconds. The documentation provided by PHP isn’t the only good part, read peoples comments on real application usage of function. For example the sleep function (http://www.php.net/manual/en/function.sleep.php) , it not only shows usage of it, but mini hacks people have used to get it working better, or an alternative way to do it.

But i must say its an nice phone and love using it.

I started working  through the tutorial for the PHP Zend Framework.  After few pages they  neglected to mention where the  piece of code is supposed to be. Maybe I learnt a lot more, but it did not make for a very ‘quick’ start to work out things go from the error messages.

Here’s the structure of the QuickStart Tutorial…
