PHP difference between echo 'string'.'\n'; and echo 'string'."\n";

Given the following statements:

echo 'string1'."\n";
echo 'string2';

The following gets rendered as output: 

string1
string2

With these statements

echo 'string1'.'\n';
echo 'string2';

This gets rendered (note the verbatim backslash n): 

string1\nstring2

When \n is in double quotes, it makes a new line as it should. when \n is in single quotes, it will be shown in the browser as text.

Can anyone explain this behavior?

Using single quotes will mark it as a string, so PHP will literally output \n.

See here: PHP Manual

Alternatively use chr() with the ASCII code of a new line as an argument:

echo 'string'.chr(10);

Or use the <br/> Tag

echo 'string<br/>';

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters
