Write a simple function that converts all strings into uppercase letters:

Now we develop a php extension to implement the my_toupper function.

Step 1:

PHP provides an extension framework generator: ext_skel, which is in the ext directory of php source code (my is/usr/local/src/php-5.6.17/ext. First, create an orlion. skel file in the ext Directory of the php source code. the file content is:

string my_toupper(string str)

This file tells ext_skel that our extension contains the my_toupper function. then, execute:

./ext_skel --extname=orlion --proto=orlion.skel

In this step, an orlion folder is created under the current directory. The directory structure is as follows:

At this time, the extended framework is ready.

Step 2:

Modify config. m4 in the orlion directory and remove the dnl of lines 10th, 11, and 12 of this file:

Is

Changed:

Step 3:

Next we need to implement our function. open orlion. c, find the function PHP_FUNCTION (my_toupper), and modify it to the following:

Then compile the extension and run the following commands in sequence:

$ /usr/local/php/bin/phpize$ ./configure --with-php-config=/usr/local/php/bin/php-config$ make

Step 4:

Add the extension to php. first, copy orlion/mudules/orlion. so in our extension to the extension directory of php:

Modify the configuration of php. ini and add "extension = orlion. so" to the end of the file, and then restart php-fpm.

Step 5:

Write a test. php file and test it:

Run the command and you can see that ABC and success are output!
