raymondjplante / SplClassLoader.php
Last active December 15, 2015 20:59 — forked from jwage/SplClassLoader.php
Autoloader functions should do their magic then return true or false (that way a later autoloader can maybe succeed). Requiring a file without the checking first if it's valid will fatal error.
