from flask import Flask
from flask_sqlalchemy import SQLAlchemy
import os

app = Flask(__name__)

# Adjust the DATABASE_URL format for SQLAlchemy compatibility
database_url = os.getenv("DATABASE_URL", "")
if database_url.startswith("postgres://"):
    database_url = database_url.replace("postgres://", "postgresql+psycopg2://")

app.config["SQLALCHEMY_DATABASE_URI"] = database_url

# Initialize the SQLAlchemy object
db = SQLAlchemy(app)

# Sample route to test the setup
@app.route("/")
def index():
    return "Database URI setup complete!"

if __name__ == "__main__":
    app.run()

• This code retrieves the DATABASE_URL from the environment.
• If DATABASE_URL starts with postgres://, it replaces it with postgresql+psycopg2://.
• The db instance is initialized with SQLAlchemy(app) for use with SQLAlchemy ORM.
• The replacement of "postgres://" with "postgresql+psycopg2://" is necessary because of a compatibility issue between the URI format provided by Heroku and the URI format expected by SQLAlchemy.

To enable all error debugging in PHP, you can use the following PHP code snippet. This will display all errors, warnings, and notices:

<?php
// Turn on all error reporting
error_reporting(E_ALL);

// Display errors
ini_set('display_errors', 1);

// Optionally, you can log errors instead of displaying them
// ini_set('log_errors', 1);
// ini_set('error_log', '/path/to/php-error.log');

echo "Error reporting is enabled.";
?>
