What causes the "unterminated string literal" error?

Question

JSON

In general, we have the following picture in one folder:
1. A PHP file that, when requested, "returns" a binary array in JSON format using the json_encode() function; . That is, something like this:

[ { "1": "A", "2": "C", "3": "D"}, { "11": "OLOLO" } ]

2. Page, also PHP, where there is such a line:

<script type="text/javascript">
      var CatTheColors = JSON.parse('<?php echo file_get_contents("tot_file_vishe.php"); ?>');
</script>

Well, after loading the page in the source code, I see:

var CatTheColors = JSON.parse('[
    {
        "1": "A",
        "2": "C",
        "3": "D",
    },
    {
        "11": "OLOLO"
    }
]');

And in the console, the browser swears at "unterminated string literal", that is, at the first line of code above. Why? What's wrong?

Answer 1

And 1 more question. Moved the first PHP file to a directory above, writing I
get an error about the "Non-existence" of this file, although it is 100% there :\
Why?
