Unclosed single quote in php tag causes formatting changes which break php code

[esetnik]

This issue is opened by request in #490 (comment)

Description

$_SERVER['DOCUMENT_ROOT '] will be broken after formatting php code sample below with js-beautify. This was originally discovered as an issue with vscode-php-cs-fixer which relies on js-beautify for html beautification. See junstyle/vscode-php-cs-fixer#42

Input

The code looked like this before beautification:

<a href='' onclick='doIt("<?php echo str_replace("'", "\\ ", $var); ?>  "); '>
  Test
</a>
                
<?php include_once $_SERVER['DOCUMENT_ROOT'] . "/shared/helpModal.php";  ?>

Expected Output

The code should have looked like this after beautification:

<a href='' onclick='doIt("<?php echo str_replace("'", "\\ ", $var); ?>  "); '>
                            Test
                        </a>
                
<?php include_once $_SERVER['DOCUMENT_ROOT'] . "/shared/helpModal.php";  ?>

Actual Output

The code actually looked like this after beautification:

<a href='' onclick='doIt("<?php echo str_replace("' ", "\\ ", $var); ?>  "); '>
                            Test
                        </a>
                
<?php include_once $_SERVER['DOCUMENT_ROOT '] . "/shared/helpModal.php";  ?>

Note the single space added at the end of 'DOCUMENT_ROOT' in associative array reference. This changes the key.

Steps to Reproduce

1. Go to jsbeautfy.org
2. Paste above example
3. See actual output instead of expected output
