1 生成框架

./ext_skel --extname=PHPTool

2 修改默认参数

vim config.m4

PHP_ARG_WITH(myext, for myext support,dnl Make sure that the comment is aligned:[  --with-myext             Include myext support])dnl Otherwise use enable:dnl PHP_ARG_ENABLE(myext, whether to enable myext support,dnl Make sure that the comment is aligned:dnl [  --enable-myext           Enable myext support])

PHP_ARG_WITH 与 PHP_ARG_ENABLE 二选一

vim php_PHPTool.h

PHP_FUNCTION(confirm_PHPTool_compiled) confirm_PHPTool_compiled ===> PHPTool

vim PHPTool.c

confirm_PHPTool_compiled ===> PHPTool(全部替换)

3添加函数

PHP_FUNCTION(PHPTool){zend_printf("Hello PHP!");}

4 编译添加

/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmake && make install

vim php.ini

extension = "PHPTool.so"

/usr/local/php/sbin/php-fpm restart

5 测试

php -r 'echo PHPTool();'

Hello PHP!
