Can I override the PHP built-in function echo()?

Question

I recently looked at my source code and it was a real mess.

my php source:

echo \'
Rar
\';
echo \'Rar\';
e

You can indirectly overload echo() by using the __toString() magic method like so:

content= $c;
    }

    public function __toString() {
        return $this->content . '\r\n';
    }
}

$text= new CleanOutput('Hello world!');
echo $text;
?>

The above would output "Hello world!" with a newline and carriage return appended at the end. There's ways to further encapsulate this, but they are outside the scope of my answer.

Edit:
As was noted, the above solution is slow/clumsy. Here's a more elegant solution using output buffering:

This is faster and cleaner (although it technically doesn't 'override' echo).
