Optimization and 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 yet basic debugging technique is to turn on error reporting. Another, slightly more advanced technique involves using print statements, which can help pinpoint harder-to-find bugs by displaying what actually appears on the screen. PHPEclipse is an Eclipse plug-in that highlights common syntax errors and can be used in conjunction with the debugger to set breakpoints.

Setup

To learn the concepts described in this article, PHP, a web server, and Eclipse are required. The debugger extension supports PHP version V5.0.3.

We need a web server to parse pages created with PHP and display them to the browser. Apache2 is used in this article. However, any web server will suffice.

To take advantage of some of the debugging techniques described 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'll also need to download it.

Also requires the PHP debugger extension module. Installing it is a little tricky. Please follow the instructions for installing the debugger extension carefully. Now, comment out the lines in the php.ini file that require the PHP extension to be loaded and configured. Uncomment it when you need to use the debugger.
