php foreach glob 多个扩展

Question

必须有更好的方式来写这个:

<?php $imagecounter = "no";
    foreach (glob("images/*.jpg") as $image)    {
    $imagecounter = "yes";
    }
    foreach (glob("images/*.png") as $image)    {
    $imagecounter = "yes";
    }
    foreach (glob("images/*.gif") as $image)    {
    $imagecounter = "yes";
    }
    if ($imagecounter == "yes"){Create gallery}?>

该文件夹可能也有不应创建图库的 zip 或 pdf 文件

Answer 1

if(glob("images/*.{jpg,png,gif}", GLOB_BRACE))
{
  //create gallery
}

就是这样:)
