Lightweight way to get extension for *nix systems <?php function get_extension($path) { $c = preg_match('#[^\/]+\.([^\.]*)$#uis', $path, $tmp); return $c ? $tmp[1] : null; } ?> this will return NULL for dotfiles (hidden files) Testing: <?php $test = array( '/normal_dir/normal.foo', '/double_ext.foo.bar', '/.hidden/empty_ext.', '/.hidden_dir/.hidden_file', '/foo.bar/no_ext' ); foreach($test as $path) { var_dump(parse_extension($path)); } ?> results: string(3) "foo" string(3) "bar" string(0) "" NULL NULL if you want to get all extensions (substring of file name after first dot) use another expression: <?php $c = preg_match('#[^\.|\/]+\.([^\/]*)$#uis', $path, $tmp); ?> ---- Server IP: 72.52.91.14 Probable Submitter: 37.17.45.76 ---- Manual Page -- http://php.net/manual/en/function.pathinfo.php Edit -- https://master.php.net/note/edit/120300 Del: integrated -- https://master.php.net/note/delete/120300/integrated Del: useless -- https://master.php.net/note/delete/120300/useless Del: bad code -- https://master.php.net/note/delete/120300/bad+code Del: spam -- https://master.php.net/note/delete/120300/spam Del: non-english -- https://master.php.net/note/delete/120300/non-english Del: in docs -- https://master.php.net/note/delete/120300/in+docs Del: other reasons-- https://master.php.net/note/delete/120300 Reject -- https://master.php.net/note/reject/120300 Search -- https://master.php.net/manage/user-notes.php
