Here doc in PHP4 has one very interesting gotcha. If you save files in Windows format, to be displayed via a UNIX system, you'll get a parse error every time you try to use a here doc statement as in print <<<EOT EOT; etc. This is because the Windows file will contain \r\n by default, but the PHP parser in UNIX is looking for only \n at the end of the <<<EOT part. Because these characters are invisible in most editors, you won't know that this mixup is happening. Solution: use an editor that allows you to save a file in UNIX newline format, or write a regex to do it manually. This took me a while to figure out. Should save someone else from graying prematurely. http://www.php.net/manual/language.types.string.php
