macos - Mac's built-in PHP annotation configuration extension is invalid, what is the reason?

Question

< /p>

< /p>

[Question]: These extensions will still take effect even if they are commented out. What is the reason?

PS: Apache has been restarted and the computer has been restarted, but it is ineffective. This is the PHP that comes with mac. The version is:
PHP 5.5.38 (cli) (built: Aug 21 2016 21:48:49) < br>Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2015 Zend Technologies

Answer 1

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

Answer 2

Is there a dll suffix on mac?

Answer 3

The wrong file should be corrected.

Answer 4

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

Answer 5

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

Answer 6

This item is the actual loaded configuration file
