date - Use of DateTime in PHP echo -


i have set variables display current year this:

$now = new datetime(); $year $now->format("y");

i using echo this: 

echo $str='hello world, year $year';

this not displaying year however, doing wrong?

  1. you're missing = sign in variable assignment
  2. you have string in single quotes keeps variable being interpolated

.

$now = new datetime(); $year = $now->format("y"); echo "hello world, year $year";
