Installation

To install the library, make sure you have Composer installed and using your command terminal run the following:

composer require yizack/instagram-feed

Use

Installing this library will allow you to use the InstagramFeed class by simply importing the composer autoload.

Import the composer autoload, use the namespace Yizack\InstagramFeed and initialize the InstagramFeed object.

require "vendor/autoload.php";
use Yizack\InstagramFeed;

$feed = new InstagramFeed(
  "long-lived-access-token" // Paste your long-lived-access-token here
);

To retrieve your Instagram feed array use the getFeed() function.

$array = $feed->getFeed();

Or loop it directly in a foreach method wherever you need it.

foreach ($feed->getFeed() as $value) {
    // your code
}

The getFeed() function also accepts a comma-separated list of fields to be returned.

$array = $feed->getFeed("username,permalink,timestamp,caption,media_url");

For a list of all available fields see: https://developers.facebook.com/docs/instagram-basic-display-api/reference/media#fields

About the code

`InstagramFeed` constructor arguments

Argument	Type	Description	Optional	Default value
`token`	string	Your Instagram Basic Display `long-lived-access-token`.	No
`path`	string	The path where the updated file will be saved on your server.	Yes	`ig_token`
`filename`	string	The name of the file in which the date of the last token update will be stored.	Yes	`updated.json`

`getFeed()` function

Updates the date of the last token update and requests feed data from an Instagram account.

Returns an array with the data of the last 25 posts with the following data for each one:

Key	Description
`username`	Instagram username.
`permalink`	Instagram post permalink.
`timestamp`	Instagram post timestamp.
`caption`	Instagram post caption.
`id`	Instagram post identifier.

Long-Lived Access token

This approach uses Long-Lived Access Tokens obtained by authorizing your Instagram account with your Meta App.

Since Long-lived tokens are valid for 60 days and can be refreshed as long as they are at least 24 hours old and not expired, the getFeed() method will refresh your token everytime it is been called if 24 hours have passed.

Tokens that have not been refreshed in 60 days will expire and can no longer be refreshed, so be sure to visit often the site where you placed the feed.

Example of use
