How can the use of Composer simplify the process of installing and managing PHP frameworks and dependencies?

Using Composer simplifies the process of installing and managing PHP frameworks and dependencies by allowing you to define the dependencies in a composer.json file and then easily install them with a single command. Composer also handles autoloading, updating dependencies, and managing versions, making it a convenient tool for PHP development.

// Example composer.json file
{
    "require": {
        "vendor/framework": "^1.0",
        "vendor/library": "^2.0"
    }
}
