PHP has Heredoc and Nowdoc strings  which are the best way to handle multiline strings in PHP   http   php net manual en language types string php language types string syntax heredoc   str    lt  lt  lt EOD Example of string spanning multiple lines using heredoc syntax   var is replaced automatically  EOD    A Nowdoc is like a Heredoc  but it doesn t replace variables    str    lt  lt  lt  EOD  Example of string spanning multiple lines using nowdoc syntax   var is NOT replaced in a nowdoc  EOD    Beware that the end token EOD must not be indented at all  or PHP won t acknowledge it  Also  you don t have to use  EOD   it can be any string you want

Not sure how it stacks up performance-wise  but for places where it doesn t really matter  I like this format because I can be sure it is using  r n  CRLF  and not whatever format my PHP file happens to be saved in    text  line1 r n           line2 r n           line3 r n     It also lets me indent however I want

Well    xml    l vv     Works   You can also use the following    xml    l nvv     or   xml    lt  lt  lt XML l vv XML      Edit based on comment   You can concatenate strings using the    operator    str    Hello    str      World   echo  str    Will echo out  Hello World

To put the strings  l  and  vv  on separate lines in the code alone    xml    l    xml     vv  echo  xml    In this instance you re saying to append    the string to the end of the previous version of that string variable  Remember that   is only an assignment operator so in your original code you re assigning the variable a new string value   To put the strings  l  and  vv  on separate lines in the echo alone    xml    l nvv  echo  xml    You don t need multiple strings in this instance  as the new line character  n will take care of that for you   To put the strings  l  and  vv  on separate lines in code and when echoing    xml    l    xml      nvv  echo  xml

Another solution is to use output buffering  you can collect everything that is being outputted echoed and store it in a variable    lt  php ob start        gt line1 line2 line3 lt  php    xml   ob get clean      Please note that output buffering might not be the best solution in terms of performance and code cleanliness for this exact case but worth leaving it here for reference
