PHP foreach glob多个扩展 [英] php foreach glob multiple extensions

问题描述

 <？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}？> 
  

该文件夹可能有zip或pdf文件，不能创建图库

$ b如果（glob（images / *。{jpg，png，gif}，GLOB_BRACE））$（$ b $ div class =h2_lin>解决方案

  b $ b {
 //创建图库
} 
  

就是这样：）

There has got to be a better way to write this:

<?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}?>

That folder might have zip or pdf files too that should not create a gallery

解决方案

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

And that's about it :)
