我已遵循Xdebug向导的说明：
-Download xdebug-2.7.0RC1.tgz
-Install the pre-requisites for compiling PHP extensions.
On your Ubuntu system, install them with: apt-get install php-dev autoconf automake
-Unpack the downloaded file with tar -xvzf xdebug-2.7.0RC1.tgz
-Run: cd xdebug-2.7.0RC1
-Run: phpize (See the FAQ if you don't have phpize).
As part of its output it should show:
Configuring for:
...
Zend Module Api No: 20180731
Zend Extension Api No: 320180731
If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.
-Run: ./configure
-Run: make
-Run: cp modules/xdebug.so /opt/lampp/lib/php/extensions/no-debug-non-zts-20180731
-Edit /opt/lampp/etc/php.ini and add the line
-zend_extension = /opt/lampp/lib/php/extensions/no-debug-non-zts-20180731/xdebug.so
Restart the webserver
但是调试不适用于Visual Studio Code，在phpinfo上Xdebug未显示为已安装扩展。如果我按照指示进行操作...我错过了什么吗？
