The PHP.ini configuration file is in the wrong location, only the extension suffix on windows is .dll

On linux and mac it’s .so

phpinfo(); take a look at loadphpini

Is there a dll suffix on mac?

The wrong file should be corrected.

These extensions are compiled into PHP

在对应的php.ini文件中修改 extesnion_dir=/your/path/to/extensions 指定一个目录， 将相应扩展放到相应目录， 然后在php.ini文件中添加 extension=pdo.so

I took a closer look and found that the php.ini that comes with mac does indeed have such a section

; If you wish to have an extension loaded automatically, use the following
; syntax:
;
; extension=modulename.extension
;
; For example, on Windows:
;
; extension=msql.dll
;
; ... or under UNIX:
;
; extension=msql.so
;
; ... or with a path:
;
; extension=/path/to/extension/msql.so
;
Now only Just change the suffix dll to .so and it’s done

This item is the actual loaded configuration file
