PHP Question

Can't Find PHP Library In My Project

I'm not a web dev (I'm a mobile developer) and trying to figure this out.


  1. I'm using this library: https://github.com/ktamas77/firebase-php

  2. I got 'composer' installed on my machine by following the documentation on composer's site.

  3. I have installed the library in #1 by using this command: 'php composer.phar require ktamas77/firebase-php dev-master'

  4. In a certain screen or php file in my project, I'm adding this:

    $firebase = new \Firebase\FirebaseLib(DEFAULT_URL, DEFAULT_TOKEN);



and when I run or go to that specific screen, there's an error like this:


Message: Class 'Firebase\FirebaseLib' not found


My question is: Why is that? Why can't this freakin php project find that FirebaseLib? I can verify that I have such file in my project, cause I can open the file from that code above.

The path of that file is this:

'/Applications/MAMP/htdocs/xxx-cms/vendor/ktamas77/firebase-php/src/firebaseLib.php'


Is adding 'require' at the top of my php file required?

I tried adding require but the error goes to that require when adding that.

Lastly, I even modified my composer.json and added "autoload" as was suggested here: How does PHP connection to firebase work?

"autoload": {

}

}


Unfortunately I wasn't able to do this instruction from that SO answer:


Then simply require Composer's Autoloader with require
"vendor/autoload.php"; and new Firebase to autoload the class.


Thanks.

Answer

You need to add the autoloader from composer into your base script or some bootstrap file.

Something like:

require "vendor/autoload.php";
