I wish I had known these 10 tips the day I started working with PHP. Instead of learning them through painstaking process, I could have been on my way to becoming a PHP programmer even sooner! This article is presented in two parts and is intended for folks who are new to PHP. Tip 1: MySQL Connection Class The majority of web applications I've worked with over the past year have used some variation of this connection class: class DB { function DB() { $this->host = "localhost"; // your host $this->db = "myDatabase"; // your database $this->user = "root"; // your username $this->pass = "mysql"; // your password $this->link = mysql_connect($this->host, $this->user, $this->pass); mysql_select_db($this->db); } } // calls it to action $db = new $DB; Simply edit the variables and include this in your files. $result = mysql_query("SELECT * FROM table ORDER BY id ASC LIMIT 0,10"); More information can be found in the manual--be sure you read the comments:
Create daemons in PHP
Everyone knows PHP can be used to create websites. But it can also be used to create desktop applications and commandline tools. And now with a class called System_Daemon, you can even create daemons using nothing but PHP. And did I mention it was easy? Update 4 Dec, 2012: Legacy Warning This class was relevant in 2009, and may still be to some people, but if you want to daemonize a php script nowadays, a 5-line Ubuntu upstart script should suffice. If you're still convinced you need to do this with pure PHP, read on. What is a Daemon? A daemon is a Linux program that run in the background, just like a 'Service' on Windows. You reading this page, would not have been possible without them. Why PHP? Most daemons are written in C. Reuse & connect existing code Think of database connections, classes that create customers from your CRM, etc.Deliver new applications very fast PHP has a lot of build in functions that speed up development greatly.Everyone knows PHP (right?)

PHP for Beginners: Building Your First Simple CMS
The Magic of PHP + MySQL It’s safe to say that nearly every website that’s up-to-date these days is using some form of content management system (CMS). While there are a ton of great free options that provide us with a CMS to power a website (WordPress, Drupal, etc.), it doesn’t hurt to peek under the hood and get a feel for how these systems work. To get our feet wet as back-end developers, we’ll be creating a simple PHP class that will: Create a databaseConnect to a databaseDisplay a form with two fieldsSave the form data in the databaseDisplay the saved data from the database Download Files This class is intended to give you a feel for how PHP and MySQL interact together, and to show the basics of a CMS. Building the Class Our first step is to simply lay out the class in a file named ‘simpleCMS.php’ so we have a road map to work with. As you can see, we’re creating one class with four variables and five methods. The Variables Build the Database Connect to the Database Build the Form <! <?
Easy PHP Blackhole Trap with WHOIS Lookup for Bad Bots
One of my favorite security measures here at Perishable Press is the site’s virtual Blackhole trap for bad bots. The concept is simple: include a hidden link to a robots.txt-forbidden directory somewhere on your pages. Bots that ignore or disobey your robots rules will crawl the link and fall into the trap, which then performs a WHOIS Lookup and records the event in the blackhole data file. In five easy steps, you can set up your own Blackhole to trap bad bots and protect your site from evil scripts, bandwidth thieves, content scrapers, spammers, and other malicious behavior. The Blackhole is built with PHP, and uses a bit of .htaccess to protect the blackhole directory. These four files are all contained in a single directory named “blackhole”. Note: By default, .htaccess files are hidden on Windows and OS X, so to view them you need to enable “Show hidden files” on your machine, or use any FTP or code-editing software that is capable of displaying them (it’s a common feature).
