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

Although this solution does not override echo, you can get something close to echo with a newline. Add:

function e() {
    return o::singleton();
}

class o {
    private static $instance;

    public static function singleton()
    {
        if (!isset(self::$instance)) {
            $className = __CLASS__;
            self::$instance = new $className;
        }
        return self::$instance;
    }

    public function __set($prop, $txt) {
        echo $txt . PHP_EOL;
    }
}

to your file, and then you can use:

e()->o = "Line which ends in newline";

instead of echo.
