Description
     There is no function named main() 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() which is why this page exists.   Please 
     add a user comment below that mentions what PHP function caused the 
     error that linked to main() and it will be 
     fixed and properly documented.
