假定：
php编译安装路径：/usr/local/php/
apache编译安装路径：/usr/local/apache/
php配置文件路径：/etc/php.ini
php安装源路径：/usr/source/php-5.3.9/


[root@localhost ~]# cd /usr/source/php-5.3.9/ext/openssl/

[root@localhost openssl]# /usr/local/php/bin/phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module

[root@localhost openssl]# cp ./config0.m4 ./config.m4

[root@localhost openssl]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version:         20090626
Zend Module Api No:      20090626
Zend Extension Api No:   220090626

[root@localhost openssl]# ./configure --with-openssl --with-php-config=/usr/local/php/bin/php-config
注：如果不想使用php自带的ext里的openssl的话 可使用参数“--with-openssl=DIR” Include OpenSSL support (requires OpenSSL >= 0.9.6)

[root@localhost openssl]# make

[root@localhost openssl]# make install

在php.ini中加载openssl.so
[root@localhost openssl]# vi /etc/php.ini
加入：
extension = "openssl.so"

重启apache：
[root@localhost ~]# /usr/local/apache/bin/apachectl -k restart

检验方法1：
通过phpinfo检验是否加载了openssl模块

[root@localhost openssl]# cd ~
[root@localhost ~]# vi test.php
php code:

error_reporting(E_ALL);
$a = file_get_contents('https://id3check.gb.co.uk/gbportalinternational/aspx/id3check_1b.asmx?WSDL');
var_dump($a);

[root@localhost ~]# /usr/local/php/bin/php ~/test.php
返回wsdl xml文件，表示安装成功
