如何从文件夹下载所有图像

Question

I am displaying the images through the Apache server. When I click on each image it should open download.php?fiel=file_name.jpg and download the image to the system.

This is the code for Image Display

  <?php
 $files = glob("Image/"."*.*");
 for ($i=0; $i<count($files); $i++)
{
$num = $files[$i];
echo $num."<br>";
echo '<img src="'.$num.'" alt="Here should be image" width="256" height="192" >'."<br/>";
}
?>

I used the following code to download the Image (ie download.php file).

 <?php
 $file = $_GET['file'];
  header("Content-type: image");
 header("Content-disposition: attachment; filename= ".$file."");
 readfile($file);
 ?> 

How to achieve this?

Answer 1

You mean something like this? :

<?php
$files = glob("Image/"."*.*");
$countFiles = count($files); //Don't do calculations in your loop, this is really slow

for ($i=0; $i<$countFiles; $i++)
{
    $num = $files[$i];

    echo '<a href="download.php?file=' . $files[$i] . '"><img src="'.$num.'" alt="Here should be image" width="256" height="192" ></a><br/>';
}
?>

Answer 2

foreach (glob("Image/*.*") as $file) {
  echo "<a href='download.php?file=$file'>$file<br>\n";
  echo "<img src='$file' alt='Here should be image' width='256' height='192'/><br>\n</a>";
}

If you want to download all images in a single folder I would suggest you to archive your images with tools like zip or something similar. You can zip files in php on the fly. To iterate over all files in a directory take a look at RecursiveDirectoryIterator

foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir)) as $file) {
    var_dump($file);
}

Try this

if(isset($_GET['file'])){
    //Please give the Path like this
    $file = 'images/'.$_GET['file'];

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    exit;
}

}
