AFAIK, \n is global convention for newline. but
produces a\nb
and
produces ab
Can anybody explain this behavior? and how can one print newline character? I've always used <br>. thanks

If you look at the HTML source, you'll see a new line between a and b. As you mentioned, though, HTML for newline is
.

single quotation marks indicate to PHP that you want it to treat the string literally, variables and escape sequences will not be parsed and the string is simply outputted as it is (the exception being when using backslashes to escape)
strings in double quotation marks are parsed for variables and the like, and so sequences such as \n or are interpreted.

Backslashes stay with only two exceptions: \' and \\.
Code: Select all
echo '\a\p\o\s\t\r\o\p\h\e\:\ \'\,\ \b\a\c\k\s\l\a\s\h\:\ \\';
Code: Select all
\a\p\o\s\t\r\o\p\h\e\:\ '\,\ \b\a\c\k\s\l\a\s\h\:\ \

PHP does not interpret HTML entities.
