为什么没有加载 xdebug 3？

Question

我已经重启了 nginx 和 php7.4-fpm.

xdebug 3 貌似是根据这个安装的：

这是来自 phpinfo() 的目录：

加载配置文件/etc/php/7.4/fpm/php.ini 扫描此目录以获取其他 .ini 文件 /etc/php/7.4/fpm/conf.d 解析的其他 .ini 文件 /etc/php/7.4/fpm/conf.d/10-opcache.ini, /etc/php/7.4/fpm/conf.d/10-pdo.ini, /etc/php/7.4/fpm/conf.d/15-xml.ini, /etc/php/7.4/fpm/conf.d/20-bcmath.ini, /etc/php/7.4 /fpm/conf.d/20-calendar.ini, /etc/php/7.4/fpm/conf.d/20-ctype.ini, /etc/php/7.4/fpm/conf .d/20-dom.ini, /etc/php/7.4/fpm/conf.d/20-exif.ini, /etc/php/7.4/fpm/conf.d/20-ffi .ini, /etc/php/7.4/fpm/conf.d/20-fileinfo.ini, /etc/php/7.4/fpm/conf.d/20-ftp.ini, /etc/php/7.4/fpm/conf.d/20-gettext.ini, /etc/php/7.4/fpm/conf.d/20-iconv.ini, /etc/php/7.4/fpm/conf.d/20-igbinary.ini, /etc/php/7.4/fpm/conf.d/20-imagick.ini, /etc/php/7.4/fpm/conf.d/20-json.ini, /etc/php/7.4/fpm/conf.d/20-phar.ini, /etc/php/7.4/fpm/conf.d/20-posix.ini , /etc/php/7.4/fpm/conf.d/20-readline.ini, /etc/php/7.4/fpm/conf.d/20-redis.ini, /etc/php/7 .4/fpm/conf.d/20-shmop.ini, /etc/php/7.4/fpm/conf.d/20-simplexml.ini, /etc/php/7.4/fpm/conf.d/20-sockets.ini, /etc/php/7.4/fpm/conf.d/20-sysvmsg.ini, /etc/php/7.4/fpm/conf.d/20-sysvsem.ini, /etc/php/7.4/fpm/conf.d/20-sysvshm.ini, /etc/php/7.4/fpm/conf.d/20-tokenizer.ini, /etc/php/7.4/fpm/conf.d/20-xdebug.ini, /etc/php/7.4/fpm/conf.d/20-xmlreader.ini, /etc/php/7.4 /fpm/conf.d/20-xmlwriter.ini, /etc/php/7.4/fpm/conf.d/20-xsl.ini, /etc/php/7.4/fpm/conf .d/20-zip.ini

/etc/php/7.4/fpm/conf.d/20-xdebug.ini内容：

# xdebug 3 -          
zend_extension=/usr/lib/php/20200930/xdebug.so

我不知道如何检查这是否是正确的文件。他们在文档中写道：

Add the following line to php.ini:

zend_extension=/wherever/you/put/it/xdebug

我怎么知道我放在哪里？ :) 它是通过 install 命令安装的，它被放置在它放置的位置 :) 在那个目录中没有没有 .so 的文件。我只是使用了与 xdebug 2 相似的目录和文件名。

phpinfo() 不显示已加载 xdebug。

添加xdebug_info()；文件崩溃页面 - 可能未定义此功能。

Answer 1

正如@LazyOne 所说

for PHP 7.4 the folder should be 20190902

所以在ini文件中设置

zend_extension=/usr/lib/php/20190902/xdebug.so

为 Php 7.4 加载 xdebug 3。谢谢
