Optimized debugging techniques and techniques for PHP programmers (1) _php tutorial

Introduction

There are many PHP debugging techniques that can save a lot of time when coding. An effective but basic debugging technique is to turn on error reporting. Another slightly more advanced technique, including the use of print statements, is to help pinpoint bugs that are more difficult to spot by displaying what actually appears on the screen. PHPEclipse is an Eclipse plugin that emphasizes common syntax errors that can be combined with the debugger for setting breakpoints.

Set up

To learn the concepts described in this article, PHP, WEB servers, and Eclipse are required. The PHP version supported by the debugger extension is V5.0.3.

We need a WEB server to parse the pages created in PHP and display them to the browser. The Apache2 is used in this article. However, any WEB server can meet the requirements.

To take advantage of some of the debugging techniques described in this article, you need to install Eclipse V3.1.1 and plug-in PHPEclipse V1.1.8. Since Eclipse requires Java? Technology, so also download it.

PHP's Debugger Extension module is also required. It's a little bit cumbersome to install. Follow the instructions for installing the debugger extensions carefully. Now, comment out the lines in the php.ini file that require the load and configuration of the PHP extension. When you need to use the debugger, uncomment it again.
