问题描述

I have a php function to grab images from a folder for a carousel and build the carousel on those images. I have a thumbnail folder and a main img folder.

My question is, how can I modify this code or what to add in order to recognise more image file types and not only jpg. I want to support png, gif and jpg.

My code is below:

<?php $thumbs = glob("img/thumb/*.jpg"); ?>
    <?php
    if(count($thumbs)) {
      natcasesort($thumbs);
      foreach($thumbs as $thumb) {
      ?>
          <li class="item">
              <a class="fancybox" rel="gallery1" href="img/large/<?php echo basename($thumb) ?>">
                  <img src="<?php echo $thumb ?>" width="100%" alt="IiAvJmd0OwogICAgICAgICAgICAgICZsdDsvYSZndDsKICAgICAgICAgICZsdDsvbGkmZ3Q7IAoKICAgICZsdDs/cGhwCiAgICAgICAgfX0gZWxzZSB7CiAgICAgICAgICBlY2hvIA=="Sorry, no images to display!";
        }
    ?>

解决方案

Change this line :

glob("img/thumb/*.jpg")

to 

glob("img/thumb/*.{jpg,png,gif}", GLOB_BRACE)

It's important to have no spaces in the list of endings.
