Part 2- PHP Firebase Crash Course: Insert data in Realtime Database & File Setup with Bootstrap v5

Undefined variable $database

please help me make the steps to connect Firebird Database with PHP

Warning: require(C:\xampp\htdocs\PHP-Backend\config/vendor/autoload.php): failed to open stream: No such file or directory in C:\xampp\htdocs\PHP-Backend\config\dbcon.php on line 3

Fatal error: require(): Failed opening required 'C:\xampp\htdocs\PHP-Backend\config/vendor/autoload.php' (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\PHP-Backend\config\dbcon.php on line 3

Question: Can you add custom key to data your adding in realtime database?
nvm i got it :
instead of `$postRef = $database->getReference($ref_table)->push($postData)
i needed to do: $postRef = $database->getReference($ref_table)->getChild($uid)->set($postData);`

because firestore database can't connect it always shows this error: Fatal error: Uncaught Error: Class 'Google \ ApiCore \ Serializer' not found

"The path of a URI with an authority must start with a slash "/" or be empty." I keep getting this error

Hello​ sir, can you give me a simple project?

I believe you faced an issue with relative/absolute path , in the first video you have included json and dbconfig file in separate folder , but now in the second video you have moved them to the main path , it took couple of hours for me figure it out

Thank you for making this video. This really helps me when I do my homework. Hopefully you are always healthy and can make videos that are useful again for everyone.💜

data is not inserting but no errors can u please help me

also is it necessary to take the data from firebase and put in a backend database like phpmyadmin, if yes then why so?
