PHP简单实现遍历目录下特定文件的方法小结

foreach (glob("modules/.php") as $filename) {
  echo $filename;
}

function iterator($pattern, $__FILE__) {
 preg_match("/^(.+)\/[^\/]+$/", $__FILE__, $matches);
 $ls = `ls $matches[1]/$pattern`;
 $ls = explode("\n", $ls);
 array_pop($ls); // remove empty line ls always prints
 foreach ($ls as $inc) {
  echo($inc);
 }
}
iterator("modules/.php",__FILE__);
