output:
helllo
world!
Code b:
Copy code The code is as follows:
echo'hellon';//Use n in unix system; rn in windows system
echo'world!';
?>
output:
helloworld!
Analysis: The browser cannot recognize n or rn, these two The newline character is a text newline character, and the text file is valid; viewing the HTML source code in the web page, you can find that code b successfully implements newline
Summary: If you need to output the results to the browser or print to the monitor, Use in the code; If you just want to wrap the line in the source code, use n or rn
