What is the difference between using double quotes and escaping characters in PHP string manipulation?

When working with strings in PHP, using double quotes allows for the interpolation of variables within the string. However, if you need to include special characters like double quotes or backslashes within the string, you need to escape them using a backslash (\) to prevent them from being interpreted as part of the string syntax. 

// Using double quotes and escaping characters in PHP string manipulation
$string1 = "This is a \"double quoted\" string";
$string2 = 'This is a \'single quoted\' string';

echo $string1; // Output: This is a "double quoted" string
echo $string2; // Output: This is a 'single quoted' string
