Self Highlighting Code

Using some borrowed code from www.php.net, I came up with this chunk of code that can be included at the top of a PHP script to make it highlight itself in a web browser. However, the first opening PHP tag in the output has a space or two in front of it. Does anyone know why? <? print "<style>.ln{color:#000000;width:40px;font:normal 10px courier;}</style>"; // _ignore_ $contents = highlight_file(basename($_SERVER['PHP_SELF']), true); // _ignore_ $contents = explode("<br />", $contents); // _ignore_ $ln = 1; // _ignore_ foreach($contents as $line) if(!strstr($line, "_ignore_")) { print "<span class=ln>$ln:</span>$line<br>"; $ln++; } // _ignore_ exit; // _ignore_ print "Hello, cruel world. "; while(true) print "God I love PHP. "; ?>
