php foreach glob多个扩展

Question

必须有一个更好的方法来写这个:

<?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}?>

该文件夹也可能包含zip或pdf文件,不应创建图库

Answer 1

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

这就是它:)
