How to add openssl module to php without recompiling PHP

yum -y install openssl

/usr/local/bin/ is the installation directory of php
Switch to the etx/openssl directory of the php installation directory
cd /root/soft/php-5.2.8/ext/openssl

/usr/local/bin/phpize

Cannot find config.m4.
Make sure that you run '/usr/local/bin/phpize' in the top level source directory of the module

Check that there are config.w32 and config0.m4 in the openssl directory, and rename config0.m4 to config.m4.
mv config0.m4 config.m4

Execution:

/usr/local/bin/phpize

Compile:

./configure --with-openssl --with-php-config=/usr/local/bin/php-config 
make;make install

After prompting success, add extension = openssl.so to php.ini
Restart apache or php-fpm and complete.

PS: I don’t understand why the directory contains config0.m4 instead of config.m4.
There is also config0.m4 in the pcre, zlib and other module directories.
