换行符php python

Question

I have a python script (p.py)with a text like this

print "Hello"+"\n"
print "World"

I am running this file in wamp under php / apache

<?php 

$output = system("C:\\python27\\python.exe p.py")

?>

I get the following on my browser

Hello World

without new line

How do I make sure the new line character appears. I also tried "\\r\\n"

Answer 1

You will need to wrap this in <pre> tags, or use <br/> .

Try viewing something like:

<p>
This is
a test
</p>

In a web browser. You will get no newline. That's because HTML pretty much ignores newlines. You will have to use the <br/> tag for this.

Answer 2

Evidently the output is HTML. If you inspect the source text of the page, you probably will see the newline.

Either use <br> or:

<?php 
header("Content-Type: text/plain");
$output = system("C:\\python27\\python.exe p.py")
?>
