If you want to build killer web apps though, php error reporting all it's vital that you understand the process thoroughly. This article breaks down the fundamentals of debugging in PHP, helps you php display_errors understand PHP's error messages and introduces you to some useful tools to help make the process a little less painful. Doing your Ground Work It is important that you configure PHP correctly php verbose command line and write your code in such a way that it produces meaningful errors at the right time. For example, it is generally good practice to turn on a verbose level of error reporting on your development platform. This probably isn't such a great idea, however, on your production server(s). In a live environment you neither want to confuse a genuine user or give malicious

users too much information about the inner-workings of your site. So, with that in mind lets talk about the all too common "I'm getting no error message" issue. This is normally caused by a syntax error on a platform where the developer has not done their ground work properly. First, you should turn display_errors on. This can be done either in your php.ini file or at the head of your code like this: ini_set('display_errors', 'On'); Tip: In these code examples I omit the closing (?>) PHP tag. It is generally considered good practice to do so in files which contain only PHP code in order to avoid accidental injection of white space and the all too common "headers already sent" error. Next, you will need to set an error reporting level. As default PHP 4 and 5 do not show PHP notices which can be important in debugging your code (more on that shortly). Notices are generated by PHP whether they are displayed or not, so deploying code with twenty notices being generated has an impact upon the overhead of your site. So, to ensure notices are displayed, set you

Table of contents Introduction Setting up Error messages Introducing print statements Using PHPeclipse Using the debugger Summary Download Resources Comments php error reporting IntroductionThere are many PHP debugging techniques that can save you countless hours when coding. An effective but basic debugging technique is to simply turn on error reporting. Another slightly more advanced technique involves using print statements, which can help pinpoint more elusive bugs by displaying what is actually going onto the screen. PHPeclipse is an Eclipse plug-in that can highlight common syntax errors and can be used in conjunction with a debugger to set breakpoints.Setting upTo learn the concepts described in this article, you are going to need PHP, a Web server, and Eclipse. The latest version of PHP supported by the debugger extension is V5.0.3. We need a Web server to parse the pages you create in PHP and display them to the browser. This article uses Apache V2. However, any Web server will suffice. To take advantage of some of the debugging techniques in this article, you need to install Eclipse V3.1.1 and the plug-in: PHPeclipse V1.1.8. Since Eclipse requires Java™ technology, you also need to download that. You also
