main - Dummy formain(3)

	There  is  no  function  named	main(3)  except  in  the  PHP  source.	In  PHP  4.3.0,  a  new  type  of error handling in the PHP source
       (php_error_docref) was introduced. One feature is to provide links to a	manual	page  in  PHP  error  messages	when  the  PHP	directives
       html_errors (on by default) and docref_root (on by default until PHP 4.3.2) are set.

	Sometimes  error messages refer to a manual page for the function main(3) which is why this page exists. If you discover such a reference,
       please file a bug report, indicating the PHP function caused the error that linked to main(3) and it will be fixed and properly documented.

       Known errors that point to main(3)
