PHP Security by Example

Almost an entire month has passed since my last blog entry, and a lot has happened. I'll try to catch up over the next week or two.

About a week ago, the Flash version of PHP Security by Example was Dugg.

I'm always disappointed to see trolls (Digg seems to have a bigger problem with this than Slashdot), but a few of the comments raise some valid questions. I'll try to summarize and answer those here.

It's true that slides are never a substitute for a talk, and this is especially true for this one, because it's a hands-on workshop. It's something Marco calls a BYOL (bring your own laptop), and it involves a lot of one-on-one attention and hand-holding.

The reason it's in Flash is because the person submitting the story linked to the Flash version. :-) To be fair, the only other format available for this talk is PDF. I've been wanting to create a nice web application for viewing Keynote slides. I think the best approach might be to export the slides as images, and create a simple slide navigator. I can always continue to also offer PDF, Quicktime, and Flash formats.

php arrays

Array: An array is a variable,which can store multiple values in a single variable with same data type. A data type may be number or string or any data type.
In PHP, there are three kind of arrays:
Numeric array - An array with a numeric index
Associative array - An array where each ID key is associated with a value
Multidimensional array - An array containing one or more arrays


1) Numeric arrary example:


<?php
$course=Array("php","java","dotnet","C++");

echo "$course[0]<br/>";
echo "$course[1]<br/>";
echo "$course[2]<br/>";
echo "$course[3]<br/>";
?>

Out Put:
php
java
dotnet
C++

2)Associative array
<?php

$course=array("java"=>jsp,"dotnet"=>asp,"c++"=>oops);
echo "java is basic for" .$course['java']."learning<br/>";
foreach($course as $cat=>$dept)
{
echo $cat."=>".$dept;
echo "<br/>"; }
?>

?>

Out put:
java is basic forjsplearning
java=>jsp
dotnet=>asp
c++=>oops

3)Multidimensional array<?php
$books = array(
array('Engineering','Civil', 'ComputerScience','Mechanical'),
array('Management','Hospitality','HumanResource','Quality'),
);?>
<table border="1"><tr>
<th>Category Name</th>
<th>Dept-1</th>
<th>Dept-2</th>
<th>Dept-3</th> </tr>
<?php
foreach($books as $cat){
echo '<tr>';
foreach($cat as $dept) {
echo "<td>$dept</td>"; }
echo '</tr>';}
?>


Out put:

Category Name	Dept-1	Dept-2	Dept-3
Engineering	Civil	ComputerScience	Mechanical
Management	Hospitality	HumanResource	Quality
