This is the PHP OpenID library by JanRain, Inc. You can visit our website for more information about this package and other OpenID implementations and tools:
First, run the examples/detect.php script either from the command
line or via the web. It will generate a report of any system
configuration changes necessary to run the library.
You will need PHP 5.6.0 or greater to use this library.
Follow these steps:
-
Install dependencies.
-
Enable either the GMP extension or Bcmath extension. (GMP is STRONGLY recommended because it's MUCH faster!) This is required.
-
Enable the CURL extension.
-
If you plan to use SQLite, PostgreSQL, or MySQL to store OpenID data, you'll need PEAR MDB2. You can install this by running this as root:
pear install MDB2
You'll also need to install and enable the appropriate PHP database extension. Alternatively, you can store OpenID data on the filesystem instead of using a relational database. Nothing special is required for using the filesystem method.
-
Install either the DOM or domxml PHP XML processing extension, but not both (they are incompatible).
-
-
Copy the
Auth/directory into your PHP include path.
You can use the example code to test your setup. To run the example
consumer or server, follow the instructions in the examples/README.md
file.
The best way to get started using the API is to take a look at the
example consumer and server in the examples/ directory. See the
examples/README.md file for more details.
-
If you're unable to use an OpenID URL with the library, you may want to try using the discover tool (
examples/discover.php). This tool will perform OpenID discovery on the identifier and give a list of discovered OpenID services and their types. -
On some systems, PHP basedir restrictions prevent web servers from opening a source of randomness, such as
/dev/urandom. If your PHP OpenID library has trouble getting a satisfactory source of randomness, check your Apache and PHP configurations to be sure that the randomness source is in the list of allowed paths for theopen_basediroption. -
In some cases, bugs in the GMP math library will result in signature validation errors when using this library. Since GMP is preferred over bcmath (for performance), you will have to define
Auth_OpenID_BUGGY_GMPin your application before importing any of the library code:
define('Auth_OpenID_BUGGY_GMP', true);- Not all PHP installations support SSL. You can find out if yours
supports SSL by reading the "HTTP Fetching" section of the output of
examples/detect.php.If your installation does not support SSL, thenhttps://identity URLs and server URLs will not be supported by the library. An attempt to use such an identity URL will be equivalent to using an invalid OpenID. To enable SSL support, recompile PHP with OpenSSL support or install the appropriate OpenSSL module for your platform. If you are using CURL, CURL will need to be built with OpenSSL support.
