Your version of PHP wasn't compiled with the opensslmodule. If you are building from source, add the module like so:
您的 PHP 版本未与该openssl模块一起编译。如果您是从源代码构建，请像这样添加模块：
cd /path/to/php-5.4/
./configure --with-openssl

I had the same issue. I solved it by editing my php.inifile - changing ;extension=php_openssl.dllto extension=php_openssl.dll.
我遇到过同样的问题。我通过编辑我的php.ini文件解决了它- 更改;extension=php_openssl.dll为extension=php_openssl.dll.
(For my installation, my php.inifile was located in my P:\Program Files\EasyPHP-12.1\conf_files\directory.)
（对于我的安装，我的php.ini文件位于我的P:\Program Files\EasyPHP-12.1\conf_files\目录中。）

It means you do not have the openssl extensionenabled in your PHP install. It needs to be enabled for you to use openssl_* functions.
这意味着您没有在 PHP 安装中启用openssl 扩展。需要启用它才能使用 openssl_* 函数。

Your php installation either does not have openssl enabled, or you could be running a version of php < 5.3.
您的 php 安装要么没有启用 openssl，要么您可能正在运行 php < 5.3 的版本。
To enable openssl, you must re-compile and install php with the "–with-openssl" flag. See php installation documentation
要启用openssl，您必须使用“–with-openssl”标志重新编译和安装php。见php安装文档

Check your configuration php.ini:
检查您的配置php.ini：
; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
;extension_dir = "./"
; On windows:
extension_dir = "ext"
extension=php_openssl.dll
