PHP equivalent question

What is the PHP equivalent to <!-开发者_JAVA百科-#echo var="HTTP_REFERER" --> and what code language is <!--#echo var="HTTP_REFERER" -->.

As other answers have noted, the equivalent directive is:

<?php echo $_SERVER['HTTP_REFERER']; ?>

But, to answer your other question, the language you quote in your question is 'Server Side Includes', or, at least, seems to be.

<?php echo $_SERVER['HTTP_REFERER']; ?>

$_SERVER['HTTP_REFERER'];

Good luck!

<?php
  echo $_SERVER['HTTP_REFERER'];
?>

More server related information is also in the $_SERVER array
