consider these 2 classes: namespace foo\bar; use logicexception; use memcached; class baz extends memcached { public function testbaz() { throw new logicexception('not implemented'); } } the same class written as: namespace foo\bar; class baz2 extends \memcached { public function testbaz() { throw new \logicexception('not implemented'); } } is there diffrence in performance of these 2 classes? if use composer's optimized autoloading? also consider these 2 classes: namespace foo\bar; use acme\demo; class kaz { public function init(demo\unita $unita, demo\unitb $unitb) { // } } the same coded as: namespace foo\bar; use acme\demo\unita; use acme\demo\unitb; class kaz2 { public function init(unita $unita, unitb $unitb) { // } } and again same questions: there performance diffrence between two? if use composers optimized autoloading? to clarify questions: there ...
