PHP string to JavaScript

I am trying to copy the string 

 $str = '
         this
         is
         my
         string';

to a JavaScript variable like so

 var str1 = '<?php echo $str ?>';

but when I do, I get an error 

Uncaught SyntaxError: Unexpected token ILLEGAL

If you are asking yourself why I'm doing this, I create a <table> with PHP and insert it to the $str variable and want to later use it in a JavaScript function.

You should just use json_encode() from http://www.php.net/manual/en/function.json-encode.php

Example:

var str1 = <?php echo json_encode($str) ?>;

It takes care of converting newlines to \n, escaping any other special characters as necessary, preserve spaces, etc.

Example output for your string:

var str1 = "\n         this\n         is\n         my\n         string";

JavaScript doesn't like multiline string literals or have a here-doc syntax. Try changing your string to 

$str = ' \
         this \
         is \
         my \
         string';

Javascript does not except multiline strings. You can put a backslash before the end of each line if you want to keep it looking like that.

Problem is EOL character in your PHP strng.

Use it like this (after replacing all EOL characters with a space):

var str1 = '<?php echo str_replace("\n", " ", $str) ?>';

Have you tried this?

var str1 = '<?php echo $str; ?>';

Notice the semicolon.
