Print newline in PHP in single quotes

Question

I try to use single quotes as much as possible and I ve noticed that I can t use  n in single quotes  I know I can just enter a newline literally by pressing return  but that screws up the indentation of my code   Is there some ASCII character or something that I can type that will produce newline when I m using single quotes

No  according to documentation  PHP recognize no special symbol in single quotes  And there is no single reason to use single quotes as much as possible

There IS a difference on using single VS double quotes in PHP  e g  1  echo   var n   2  echo   var n     in 1  PHP will print literally   var n in 2  PHP will have to search the location in memory for  var  and return the value in that location  also  it will have to parse the  n as a new line character and print that result   We re in the range of millionths of a second  but there IS a difference in performance  I would recommend you to use single quotes whenever possible  even knowing you won t be able to perceive this performance increase  But I m a paranoid developer when it comes to performance

I wonder why no one added the alternative of using the function chr     echo  Hello World     chr 10     or  more efficient if you re going to repeat it a million times   define  C NewLine   chr 10        echo  Hello World     C NewLine    This avoids the silly-looking notation of concatenating a single- and double-quoted string

The only escape sequence you can use in single quotes is for the single quote itself    foo    That  s great     The only way you could insert a new line into a string created with single quotes is to insert a literal newline   bar    That  s cheating
