1. You can add \n in a double quoted string. Then it will be interpreted as newline character. Or you can concatenate the the constant PHP_EOL to your string. echo 'some text' . PHP_EOL; On both ways you have to put it inside <pre></pre> tags or something similar. Or add a <br> tag to the string. echo 'something <br>';

UraL , you can concatenate the string with \n in double quotes (look at the code). The second question - "+" sign in PHP is used only for sum with numbers (integers or doubles). It's not used to concatenate strings like in JS. So both of the strings are evaluated as 0 (they are not numbers, however if string begins with number it's different). Hope now everything is clear. https://code.sololearn.com/wuGlN36q2q6R/?ref=app
