Description: ------------ The problem is that webFrontController rewrites all URI, not just the part after .phar file. Here is a trace for http://dev.mad.lan/QuizStats/quiz_stats.phar/ where it should show me the index.php from .phar file, but instead it searces for QuizStats/, that is wrong. 0.1217 551240 -> PHP_Archive::webFrontController($initfile = 'index.php') D:\Server\sites\dev\QuizStats\quiz_stats.phar:1232 0.1217 553600 -> parse_url('/QuizStats/quiz_stats.phar/') D:\Server\sites\dev\QuizStats\quiz_stats.phar:270 >=> array ('path' => '/QuizStats/quiz_stats.phar/') 0.1218 553440 -> realpath('D:/Server/sites/dev/QuizStats/quiz_stats.phar') D:\Server\sites\dev\QuizStats\quiz_stats.phar:271 >=> 'D:\\Server\\sites\\dev\\QuizStats\\quiz_stats.phar' 0.1219 553560 -> basename('D:\\Server\\sites\\dev\\QuizStats\\quiz_stats.phar') D:\Server\sites\dev\QuizStats\quiz_stats.phar:272 >=> 'quiz_stats.phar' 0.1220 553576 -> str_replace('/quiz_stats.phar', '', '/QuizStats/quiz_stats.phar/') D:\Server\sites\dev\QuizStats\quiz_stats.phar:272 >=> '/QuizStats/' 0.1220 553400 -> substr('/QuizStats/', 1) D:\Server\sites\dev\QuizStats\quiz_stats.phar:282 >=> 'QuizStats/' 0.1221 553336 -> PHP_Archive::_fileExists($archive = 'D:\\Server\\sites\\dev\\QuizStats\\quiz_stats.phar', $path = 'QuizStats/') D:\Server\sites\dev\QuizStats\quiz_stats.phar:282 >=> FALSE 0.1221 553544 -> header('HTTP/1.0 404 Not Found') D:\Server\sites\dev\QuizStats\quiz_stats.phar:283 >=> NULL >=> FALSE

Possible solution: replace line $subpath = str_replace('/' . basename($archive), '', $uri['path']); with $basename_achive=basename($archive); $subpath = str_replace(substr($uri['path'], 0, strpos($uri['path'], $basename_achive)+strlen($basename_achive)), '', $uri['path']);
