In what scenarios should developers consider using single quotes versus double quotes in PHP code that includes JavaScript?

When including JavaScript in PHP code, developers should consider using single quotes for JavaScript strings to prevent conflicts with PHP variables that are enclosed in double quotes. This helps avoid parsing issues and ensures that the JavaScript code is interpreted correctly. By using single quotes for JavaScript strings, developers can maintain clean and readable code that runs smoothly without any unexpected errors. 

<?php
$variable = "Hello";
echo "<script>";
echo 'var message = "World";';
echo "console.log('$variable ' + message);";
echo "</script>";
?>
