What is "\n" used for in PHP

[maestrodamuz]

I am new to core PHP programming, I have always beeen the dreamweaver type, but now I need to begin to know why what is what.

 

So I have been wondering what this function is used for, I have searched through the net but no solution yet.

Nothing in PHP, but it's either a line feed or a carriage return in HTML, can't remember which.

It is a newline character. It does nothing for the actual script, but gives a newline in the source code. Or wen dealin with plain text email, it creates a newline as in plain text email <br> will not do anything.

The technical definition of it, since the other two posts have just told you its name and what it's used for:

 

It stands for, and is parsed into by the PHP engine, the value of the newline character.  In ASCII, for example, the new line character is 10 (in decimal), so a char with a value of 10 would be a new line.  In C or some other lower level language it would make more sense.

 

In C:

 

char c1 = '\n';
char c2 = 10;

 

Those would be the same in memory or as human readable output.

 

 

Hrmm, so I guess this post didn't add anything new.... Oh well, already typed it.
