I'm using the slim framework
This class needs to be in composer.json , PHP can not guess where it is located and use is not equal to include as I explained in:
The composer (which Slim uses) makes use of spl_autoload that it does "program" your scripts to find the classes, in case the composer uses composer-autoload , so you have to add it to your composer.json , like this:
"autoload": {
"psr-4": {
"Slim\": "Slim",
"Classes\": "Classes"
}
},
The Classes\ is the prefix to identify by the namespace, and "Classes" is the folder where they are located, it should look similar to this:

"autoload": {
"psr-4": {
"Slim\": "Slim",
"Classes\": "Classes"
}
},
"scripts": {
"test": [
"@phpunit",
"@phpcs"
],
"phpunit": "php vendor/bin/phpunit",
"phpcs": "php vendor/bin/phpcs"
}
}
After adding in composer.json run the command:
composer dump
Or run the composer update command if you want to upgrade the classes as well as download the dependencies of Slim and other packages you've added
So it will be available in composer-autoload
