*We use single quotes when we are not evaluating anything within the* *string.
**echo "Hello World!" uses more cpu resources than echo 'Hello World'.
I* want know which of these two is better.
* <?php
** echo "This is a string with variable $test_variable"
** ?>
**  <?php
**   echo 'This is another variant of the above statement '.$test_variable
**  ?>
