How do you write and read files in PHP

In PHP, you can easily read from and write to files using several built-in functions. Here's a simple example demonstrating how to do both:


        <?php
        // Writing to a file
        $file = 'example.txt';
        $content = 'Hello, world!';
        file_put_contents($file, $content);

        // Reading from a file
        $read_content = file_get_contents($file);
        echo $read_content; // Outputs: Hello, world!
        ?>
