Question

我正在创建一个图片库，并希望我最近上传的图片位于前面。

这就是我目前所拥有的：

$files = glob("images/*.*");
for ($i=0; $i<count($files); $i++) {
    $image = $files[$i];
    $supported_file = array('gif','jpg','jpeg','png');

    $ext = strtolower(pathinfo($image, PATHINFO_EXTENSION));
    if (in_array($ext, $supported_file)) {
        echo basename($image)."<br />"; // show only image name if you want to show full path then use this code // echo $image."<br />";
        echo '<img src="'.$image .'" alt="Random image" />'."<br /><br />";
    } else {
        continue;
    }
}

但我不确定如何按照上次上传的顺序显示它。

Answer 1

$files = glob("*.{jpg,jpeg,png,gif,JPG,JPEG,PNG,GIF}",GLOB_BRACE);
$sorted_files=array(); /* a new array that have modification time as values
and files as keys the purpose is to sort files according to the values in reverse order */ 
foreach ($files as $file)
{
    $sorted_files[$file]=filemtime($file);
}
arsort($sorted_files);
foreach ($sorted_files as $image=>$mtime)
{           
    echo basename($image)."<br />"; // show only image name if you want to show full path then use this code // echo $image."<br />";
    echo '<img src="'.$image .'" alt="Random image" />'."<br /><br />";
}

如何通过上次修改从目录和订单获取图像文件？
