打印php标签和变量赋值作为文本

Question

Assume I have this text:

<?php

  $my_first_word = 'hi there';

  echo $my_first_word;

?>

And I want to print it out to the screen, only problem is when I put all the text inside a print"";

It doesn't actually print the php tags and etc, I want it to actually be outputted on the browser as text.

Answer 1

as text:

echo '<?php

$my_first_word = \'hi there\';

echo $my_first_word;

?>';

as html:

echo nl2br(htmlspecialchars('<?php

$my_first_word = \'hi there\';

echo $my_first_word;

?>'));

Do note the use of ' for quoting (otherwise the variables would not be literals), as well as the therefore escaped ' char inside the string.
