2. create a module

A. after the source code is checked out, go to the ext Directory of the source code and use ext_skel to create a module named my:

The code is as follows:

$./Ext_skel -- extname = my

B. enter the my module:

The code is as follows:

$ Cd my

C. modify the config. m4 file and find the following content:

The code is as follows:

Dnl PHP_ARG_WITH (my, for my support,
Dnl Make sure that the comment is aligned:
Dnl [-- with-my Include my support])

Make sure that the comment is aligned:
[-- With-my Include my support])

Save the file.

Tips: If you need to test whether the modification is correct, you can use php my. php to test it:

The code is as follows:

$ Php my. php
Confirm_my_compiled

Congratulations! You have successfully modified ext/my/config. m4. Module my is now compiled into PHP.

The above confirm_my_compiled is the default function of the module. after loading the module, you can call this function.
