Oracle Cloud Infrastructure SDK for PHP

About

oci-php-sdk provides an SDK for PHP that you can use to manage your Oracle Cloud Infrastructure resources.

The project is open source and maintained by Oracle Corp. The home page for the project is here.

Requirements

• PHP 8.0

Installation

Consuming the oci-php-sdk from a zip file

1. Create a directory, e.g. /path/to/artifacts
2. Place the internal OCI PHP SDK zip file, e.g. oci-php-sdk-0.0.1-2021-11-02T13-44-29.zip, in that directory.
   • If you have multiple versions of the zip file, make sure the directory only contains the version you want to use.
3. Add a dependency on oracle/oci-php-sdk version 0.0.1 to your composer.json file
4. Add a repository of type artifact to your composer.json file, where url is set to the directory with the zip file, e.g. /path/to/artifacts

Here is a complete example of such a composer.json file:

{
    "name": "oracle/oci-php-sdk-consumer",
    "type": "project",
    "require": {
        "oracle/oci-php-sdk": "0.0.1"
    },
    "repositories": [
        {
            "type": "artifact",
            "url": "/path/to/artifacts"
        }
    ]
}

5. Clear your Composer cache, vendor directory, and composer.lock file:

composer clear-cache && rm -rf vendor; rm composer.lock

• This helps make sure that vendor contains the latest contents from the zip file.

6. Run composer install
7. In your source file, e.g. src/test.php, require the vendor/autoload.php file, and then use the OCI PHP SDK classes you need. For example:

<?php

require 'vendor/autoload.php';

use Oracle\Oci\Common\UserAgent;

echo "UserAgent: " . UserAgent::getUserAgent() . PHP_EOL;

?>

8. Run the test: php src/test.php

Consuming the oci-php-sdk from a Git repository

1. Add a dependency on oracle/oci-php-sdk version dev-master to your composer.json file
2. Add a repository of type git to your composer.json file, where url is set to the same URL you use to git clone, e.g. https://github.com/organization/my-repo.git
   • Note: https://github.com/organization/my-repo.git is not an actual Git repository with the OCI PHP SDK.

Here is a complete example of such a composer.json file:

{
    "name": "oracle/oci-php-sdk-consumer",
    "type": "project",
    "require": {
        "oracle/oci-php-sdk": "dev-master"
    },
    "repositories": [
        {
            "type": "git",
            "url": "https://github.com/organization/my-repo.git"
        }
    ]
}

3. Clear your Composer cache, vendor directory, and composer.lock file:

composer clear-cache && rm -rf vendor; rm composer.lock

• This helps make sure that vendor contains the latest contents from the Git master branch

4. Run composer install
5. In your source file, e.g. src/test.php, require the vendor/autoload.php file, and then use the OCI PHP SDK classes you need. For example:

<?php

require 'vendor/autoload.php';

use Oracle\Oci\Common\UserAgent;

echo "UserAgent: " . UserAgent::getUserAgent() . PHP_EOL;

?>

8. Run the test: php src/test.php

Examples

Examples can be found here.

You may run any example by invoking the php command with the example you want to run, for example: php tests/Oracle/Oci/Examples/ObjectStorageExample.php

Documentation

Installing PHP 8.0 on Oracle Linux 8

The following has worked for installing PHP 8.0 on Oracle Linux 8:

sudo dnf module list php
sudo dnf install @php:8.0 -y

Installing Composer

Install Composer as package manager for PHP:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"
sudo mv composer.phar /usr/local/bin/composer

Running the Instance Principals Example

The tests/Oracle/Oci/Examples/InstancePrincipalsExample.php and tests/Oracle/Oci/Examples/CachingInstancePrincipalsExample.php examples must be run on an OCI instance. To set it up, you can follow these steps:

1. Create a dynamic group. You can use a matching rule like this to get all instances in a certain compartment:

   Any {instance.compartment.id = '<ocid-of-compartment>'}
   

2. Start an OCI instance. Make sure that it is matched by the dynamic group, e.g. by creating it in the correct compartment.

3. Create a policy for the dynamic group that grants the desired permissions. For example:

   Allow dynamic-group <name-of-dynamic-group> to manage buckets in compartment <name-of-compartment>
   Allow dynamic-group <name-of-dynamic-group> to manage objects in compartment <name-of-compartment>
   Allow dynamic-group <name-of-dynamic-group> to manage objectstorage-namespaces in compartment <name-of-compartment>
   

4. Install PHP 8.0 on Oracle Linux. See above.

5. Copy the OCI PHP SDK and this example to the OCI instance (using scp or rsync).

6. Run Composer to download the required packages:

   composer update
   composer install
   

7. SSH into the OCI instance.

8. Run the example:

   php tests/Oracle/Oci/Examples/InstancePrincipalsExample.php
   

9. Run the Instance Principal-specific unit tests:

   php vendor/bin/phpunit --group InstancePrincipalsRequired

Known Issues

You can find information on any known issues with the SDK here.

Thread Safety

The OCI PHP SDK is based on the GuzzleHttp\Client; therefore, it has the same threading behavior as GuzzleHttp\Client.

There does not appear to be good documentation on the thread safety of GuzzleHttp\Client, but there are hints that it is NOT thread-safe:

1. "Are you using threads (like with pthreads)? Guzzle is not thread safe and will not work in a multithreaded application" 1
2. "I would guess that the underlying cURL handles, and PHP's integration with cURL, have an issue being shared across multiple threads. You may have to create unique clients for each thread." 2

These issues are not unique to the OCI PHP SDK, and the solution seems to simply be to create a separate client per thread.
