Install yaf framework under ubuntu

Reference
http://yaf.laruence.com/manual/yaf.install.html
First, find the installation directory of php, execute info.php, check the php path

Configuration File (php.ini) Path 	/etc/php5/apache2 

Then find the address of phpize,

whereis phpize

Then cd to the decompression directory of yaf and execute

/usr/bin/phpize

If it is not in the decompression directory of yaf and there is no .m4 file, an error will be reported

Cannot find config.m4.

　　Make sure that you run /usr/local/bin/phpize in the top level source directory of the module

and then execute

 ./configure --with-php-c/bin/php-config

Please note that pcre must be installed first. If not, an error will be reported

pcre.h: No such file or directory

Install pcre

sudo apt-get install libpcre3-dev

and then execute

make

Finally execute. If you do not add sudo, there may be permission issues. Because you need to create a folder

sudo make install

Final tip:
Installing shared extensions: /usr/lib/php5/20121212/
Then load yaf.so in php.ini, restart PHP.

vi /ext/php5/apache2/php.ini

You can directly '/extension_dir' after vi ＇Search, it may look like this after finding it:
extension_dir ＝　./"
needs to be modified to:
extension_dir ＝"/usr/lib/php5/20121212/" (note that it is the location of the so file)
extension=yaf.so
Finally save and exit! ：wq!
Restart

service apache2 restart

or

sudo /etc/init.d/apache2 restart

After restarting, open info.php again and you will see

yaf support	Yaf logo enabled
Version 	2.3.3
Supports 	http://pecl.php.net/package/yaf 

The above introduces the installation of the yaf framework under ubuntu, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
