Pass a PHP string to a JavaScript variable (and escape newlines)?

Question

What is the easiest way to encode a PHP string for output to a JavaScript variable? I have a PHP string which includes quotes and newlines. I need the contents of this string to be put into a JavaScript variable. Normally, I would just construct my JavaScript in a PHP file, &#224; la: <script> var myvar = "<?php echo $myVarValue;?>"; </script> However, this doesn't work when `$myVarValue` contains quotes or newlines.

It depends on what you want to achieve, but there is a solution that always works:

$yourString = "let's find some time!!

See you soon";

$convertedToArray = ['yourString' => $yourString];

echo "let fromPHP = " . json_encode($confertedToArray) . ";";

In JavaScript, you can then use

fromPHP.yourString
