InstagramDownload - Instagram photo and Video Downloader.

Modernized version of your favorite Instagram Photo and video download helper class. If you are looking for the legacy version, see here.

I wrote this class mainly for my [online Instagram photo and video downloader] 1, but I thought share this piece for your own extensions.

• Validates Instagram URL (domain validation, URL path validation).
• Uses OG properties to detect the image and video URL.
• Verbose error reporting with proper exceptions.
• Full unit tests
• No dependencies other than PHP curl extension (which is most likely enabled by already)

Requirements

• PHP 7.1
• CURL
• Unicorn blood

Thanks to:

• MetaData - Meta data parsing regex and curl class.

Installation

With composer Install the library by running the following in your project.

composer require ayesh/instagram-download

Without composer Download the zip file from Github, and configure your autoload handler to autoload PSR-4 Ayesh\InstagramDownload namespace from the downloaded contents src directory.

You could also manually require the file. Requires a certain amount of guilty feeling because it's 2017 and you are not using a decent autoload mechanism.

require_once 'src/InstagramDownload.php'

Usage

<?php
use Ayesh\InstagramDownload\InstagramDownload;
$url = 'http://instagram.com/p/tmwAlCGygb/';

try {
  $client = new InstagramDownload($url);
  $url = $client->getDownloadUrl(); // Returns the download URL.
  $type = $client->getType(); // Returns "image" or "video" depending on the media type.
}
catch (\InvalidArgumentException $exception) {
  /*
   * \InvalidArgumentException exceptions will be thrown if there is a validation 
   * error in the URL. You might want to break the code flow and report the error 
   * to your form handler at this point.
   */
  $error = $exception->getMessage();
}
catch (\RuntimeException $exception) {
  /*
   * \RuntimeException exceptions will be thrown if the URL could not be 
   * fetched, parsed, or a media could not be extracted from the URL. 
   */
  $error = $exception->getMessage();
}
