Php delimiter format error

The following is an error code. can you see what went wrong ?? I am a beginner and have no idea what to do. but I have to try it myself to find out what is wrong. neither the book nor the tutorial will tell me where the error code is: Parse error: syntax error, unexpected $ end in H: \ wamp \ www \ testing \ test \ 2.1.4.php on line 16
Error source code:
The code is as follows:
$ Str = <
Test string

Test string

Test string
EOD;
Echo $ str;
// Defines the variables used for the delimiters
$ Name = 'Einstein ';
$ Dicta = "Imagination is more important than knowledge, because knowledge is limited, and imagination is unlimited ";
$ Size = 5;
Echo <

Said: "{$ dicta }"
EOT;
?>

Incorrect image
This error is actually very simple, that is, when the delimiter EOD and EOT end, the front side adds a Tab, the solution is to write "EOD;" and "EOT;" at the top ;". I believe that beginners have the same experience as me ......
Correct code:
The code is as follows:
$ Str = <
Test string

Test string

Test string
EOD;
Echo $ str;
// Defines the variables used for the delimiters
$ Name = 'Einstein ';
$ Dicta = "Imagination is more important than knowledge, because knowledge is limited, and imagination is unlimited ";
$ Size = 5;
Echo <

Said: "{$ dicta }"
EOT;
?>

Result:
