How do you typically start a new PHP project, especially if you are transitioning from other programming languages?

When starting a new PHP project, especially if transitioning from other programming languages, it's important to set up a proper project structure and include necessary dependencies. One common way to do this is by using a package manager like Composer to manage dependencies and autoload classes.

```php
// Composer.json file
{
    "require": {
        "monolog/monolog": "^2.0"
    }
}
```

After setting up the project structure and including necessary dependencies, you can start writing PHP code in your preferred text editor or IDE. It's also helpful to familiarize yourself with PHP's syntax and best practices to ensure a smooth transition from other programming languages.
