There’s nothing quite like having a functioning application emerge out of the controlled chaos we know as The Development Process. In Part 8 of the ongoing saga describing how to build a real world blog application using the Zend Framework we finally reach the point at which we concentrate on blog entries. At the end [...]

This entry concerns authorization. We previously covered how to authenticate an author to the blog, but we still have nothing ensuring only authenticated authors can access the new Administration Module. This is the domain of Zend_Acl, an implementation of an Access Control List system which limits access to resources by the roles assigned to a [...]

Step 1: Creating a Database Schema The schema for our blog’s database will be aimed at MySQL. We’re only starting with two tables to hold entries and authors, which may appear a little suspicious. The suspicion of course is due to the lack of two elements: Authentication and Authorisation. We’ll cover both in Part 6 [...]

Step 1: Adding Blueprint to the Project You can download the Blueprint CSS framework from http://code.google.com/p/blueprintcss/. It is released under a dual licensing system using a Modified MIT License, or the GNU General Public License. Decompress the archive of the latest 0.7 release (as at time of writing) and return to our current project’s public [...]

Step 1: Creating A New Application Before we jump into programming with the Zend Framework there are a few setup tasks. We need to install the Zend Framework, get a virtual domain running, and have a basic collection of directories and emtpy files created to hold our source code. You’ll need to download the Zend [...]

After speaking with any number of users about getting started with a framework, I find many do not have an advanced understanding of the corner stone of a current day web application framework: the Model-View-Controller Design Pattern. So let’s get over that hill right now, and before we start looking at PHP! As a bit [...]

function escape_string($varr){ //Escape array or string in postgre if(is_array($varr)){ foreach($varr as $key => $value){ $result[$key] = trim(pg_escape_string($value)); } }else{ $result = trim(pg_escape_string($varr)); } return $result; }

<?php function url_exists($url) { $handle = curl_init($url); if (false === $handle) { return false; } curl_setopt($handle, CURLOPT_HEADER, false); curl_setopt($handle, CURLOPT_FAILONERROR, true); curl_setopt($handle, CURLOPT_NOBODY, true); curl_setopt($handle, CURLOPT_RETURNTRANSFER, false); $connectable = curl_exec($handle); curl_close($handle); return $connectable; } $url = ‘http://insicdesigns.com/’; if(url_exists($url)){ echo ‘true’; }else{ echo ‘false’; } ?> Output is

This is useful if you want to display your code to your website, blog or community forum. <?php $text = ‘<?php echo \’hello world\’; ?>’; $encode = htmlentities($text); $decode = html_entity_decode($encode); echo ‘Encode ‘.$encode; echo ‘<br />’; echo ‘Decode ‘.$decode; ?>

Sample PHP Code that checks number if its Even. <?php function isEven($number){ $result = $number % 2; if($result == 0){ return true; }else{ return false; } } $number = 24; if(isEven($number)){ echo ‘The number is Even’; } ?> Output is
