Re: [PHP-DEV] file_exists and array_merge_clobber

[Greg Beaver]

In keeping with other functions that test pseudo-types like 
is_callable(), why not create a new function is_includeable() that will 
take a filename/path, and use include_path by default, or accept an 
optional array of paths to search.

if (is_includeable("somefile.php")) {
     include "somefile.php";
}
This will avoid any confusion with file_exists and more clearly define 
the purpose.  In addition, it would allow people whose hosts have put 
ini_get() and get_include_path() in php.ini's disabled_functions setting 
to still test for inclusion potential, and safely.

Regards,
Greg
