Contentstack is a headless CMS with an API-first approach. It is a CMS that developers can use to build powerful cross-platform applications in their favorite languages. Build your application frontend, and Contentstack will take care of the rest. Read More.

Contentstack provides PHP SDK to build application on top of PHP. Given below is the detailed guide and helpful resources to get started with our PHP SDK.

You need PHP version >= 5.5.0 or later installed to use the Contentstack PHP SDK.

To use the PHP SDK, you need to perform the following steps:

composer require contentstack/contentstack

To initialize the SDK, you will need to specify the API Key, Delivery Token, and Environment Name of your stack.

use Contentstack\Contentstack;
$stack = Contentstack::Stack(API_KEY, DELIVERY_TOKEN, ENV_NAME);

To use the PHP SDK, you need to perform the following steps:

1. Download/clone the PHP SDK from here.
2. Paste the downloaded ZIP file of the PHP SDK to a folder of your choice.

To initialize the SDK, you will need to specify the API Key, Delivery Token, and Environment Name of your stack.

use Contentstack\Contentstack;
include_once "contentstack/contentstack.php";
$stack = Contentstack::Stack(API_KEY, DELIVERY_TOKEN, ENV_NAME);

A stack is like a container that holds the content of your app. Learn more about Stacks.

Content type lets you define the structure or blueprint of a page or a section of your digital property. It is a form-like page that gives Content Managers an interface to input and upload content. Read more.

An entry is the actual piece of content created using one of the defined content types. Learn more about Entries.

Assets refer to all the media files (images, videos, PDFs, audio files, and so on) uploaded to Contentstack. These files can be used in multiple entries. Read more about Assets.

A publishing environment corresponds to one or more deployment servers or a content delivery destination where the entries need to be published. Learn how to work with Environments.

Install the library using Composer:

composer require contentstack/contentstack

To initialize the SDK, you will need to specify the API Key, Delivery Token, and Environment Name of your stack.

use Contentstack\Contentstack;
$stack = Contentstack::Stack(API_KEY, DELIVERY_TOKEN, ENV_NAME);

To get the API credentials mentioned above, log in to your Contentstack account and then in your top panel navigation, go to Settings > Stack to view the API Key and Delivery Token.

To find all entries of a content type, use the query given below:

$result = $stack->ContentType(CONTENT_TYPE_UID)->Query()->toJSON()->includeCount()->includeContentType()->find()
// $result[0] - array of entries
// $result[1] - content type
// $result[2] - count of the entries

To fetch a specific entry from a content type, use the following query:

$result = $stack->ContentType(CONTENT_TYPE_UID)->Entry(ENTRY_UID)->toJSON()->fetch()
// $result - entry object

You can query for content types, entries, assets and more using our PHP API Reference.

We have introduced Image Delivery APIs that let you retrieve images and then manipulate and optimize them for your digital properties. It lets you perform a host of other actions such as crop, trim, resize, rotate, overlay, and so on.

For example, if you want to crop an image (with width as 300 and height as 400), you simply need to append query parameters at the end of the image URL, such as, https://images.contentstack.io/v3/assets/blteae40eb499811073/bltc5064f36b5855343/59e0c41ac0eddd140d5a8e3e/download?crop=300,400. There are several more parameters that you can use for your images.

Read Image Delivery API documentation.

You can use the Image Delivery API functions in this SDK as well. Here are a few examples of its usage in the SDK.

// set the image quality to 100.

imageUrl = Stack->imageTransform(imageUrl, array(
'quality'=> 100));

// resize the image by specifying width and height.

imageUrl = Stack->imageTransform(imageUrl, array(
'width'=> 100,
'height'=> 100
));

// enable auto optimization for the image.

imageUrl = Stack->imageTransform(imageUrl, array(
'auto'=> 'webp'
))
