[ciapug] What does it mean?

Fri, 20 Jun 2003 16:32:26 -0500

My code starts:

#!/usr/local/bin/php
<?php
 session_start();
 $_SESSION['sessID'] = 'test';
 $_SESSION['searchID'] = 2;
// ?>
// <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
//<html>
//<head>

Both warning messages show.  Then, on the next program

#!/usr/local/bin/php
<?php
 session_start();
 echo 'The content of $_SESSION[\'searchID\'] is '
   .$_SESSION['searchID'].'<br />';
 echo 'The content of $_SESSION[\'sessID\'] is '
   .$_SESSION['sessID'].'<br />';
?>
 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 <html>

This does print the values, but the second warning shows.

My host requires "#!/usr/local/bin/php" to identify the location of PHP.
Am I doing that wrong?  Is that statement why I'm getting the warnings?
