The thing is not new, so I won’t introduce it. The following is mainly the configuration process.
First, download ZendDebugger, download link: http://downloads.zend.com/pdt/server-debugger/, because I am a win system, so I just look for the one ending in .zip. I downloaded ZendDebugger- 5.2.14-cygwin_nt-i386.zip
Then unzip and see these directories
The numbers in front of the folders represent the version of php. I am using 5.2.6, so I use 5_2_x_comp and copy the ZendDebugger.dll in this folder to the ext folder in the php directory. Then open php.ini (remember, the php.ini under wamp is in the X:wampbinapacheapache2.2.8bin directory), and add the following lines of code at the bottom:
Restart wamp, open http://localhost/ and check if php has loaded the ZendDebugger extension. This means the installation is normal
The last thing is to configure ZendDebugger in the debugger. I won’t explain it in detail here, because some people use ZendStudio and some use EPP. It’s difficult for everyone to adjust, so you can explore it yourself.
