What does phpize do?
What is Phpize? PHP Official Description:
http://php.net/manual/en/install.pecl.phpize.php
Phpize is used to extend the PHP extension module, through the phpize can build PHP plug-in module
For example, if you want to add extensions such as memcached or ImageMagick in the original compiled PHP, you can use Phpize to work through the following steps.
Second, how to use Phpize?
When PHP is compiled, the phpize script file will be available in the bin directory of PHP. Before compiling the extension module you want to add, execute the following phpize.
For example, now you want to add the memcache extension module to PHP: We're just going to do the following steps.
————————————————————————
Tar zxvf memcache-2.2.5.tgz
CD memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure–with-php-config=/usr/local/webserver/php/bin/php-config
Make
Make install
————————————————————————
NoteThe path to the Php-config file can be specified after the./configure
This completes the compilation, and it is necessary to add the extension value to the php.ini file.
Extension = "memcache.so"
---------------------------------------------------------
Note: Cannot find CONFIG.M4.
This error is a silly mistake, the decompression will require CD to the folder, or Phpize would be an error

# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
# TAR-ZVXF M4-1.4.9.tar.gz
# CD m4-1.4.9/
