php laravel how to include additional library after it was installed with composer

0 comments
Message:


In a php laravel 9 project i try to use this library:


https://packagist.org/packages/cnlpete/image-metadata-parser


I added it to composer configuration:


composer require cnlpete/image-metadata-parser

Then I add it in controller to be able to find the class.


I tried like this :


//add this into controller:
require '../vendor/autoload.php';
use cnlpete\image-metadata-parser;

And I get error
syntax error, unexpected token "-", expecting "," or ";"


Then I also added in config/app.php this:


'aliases' => [

'ImageMetadataParser' => cnlpete\image-metadata-parser\imageMetadataParser::class,
],

I see the path to the library after it was installed by composer is: myappname/vendor/cnlpete/image-metadata-parser/imageMetadataParser.php


If I use just like this without other configuration:


$imageparser = new vendor\cnlpete\image-metadata-parser\ImageMetadataParser(....);

I get error:
Error
Class "App\Http\Controllers\vendor\cnlpete\image" not found


How to include this library in the controller to be able to use it?



My Answer:
To include the library in your Laravel project after installing it with Composer, you don't need to use the `require` statement in your controller. Instead, you can simply use the namespace of the library in your controller.

Here's how you can include the library in your controller:

php
use cnlpete\ImageMetadataParser\ImageMetadataParser;

class YourController extends Controller
{
public function yourMethod()
{
// Use the library here
$parser = new ImageMetadataParser();
}
}


Make sure to use the correct namespace and class name when including the library in your controller. Also, ensure that you have run `composer dump-autoload` after installing the library to update the autoloader.
